TMETi The operating principles of an integrator intended
for solving partial differential equations of the heat conduction
type are described. The main operating part is a collection of cap-
acitors which imitate a discrete (finite-difference) representation
of the problem. For this purpose a definite number of elements form
part o the integratort each of them corresponding to a certain
part of the physical systera investigated. An element consists of
two series connected capacitors which are in turn connected to ad-
Jacent capacitors; one switching cycle corresponds to one unit of

ABSTRACT: The article deals with an entirely new type of analogs,,
the static electrointegrators (SEI). Having been un-
der development at the Problemnaya tep'Lofizicheskaya
laboratoriva Kazakhskogo universiteta (Laboratory 'or
Thermal and Physical Problems of the Kazakh University)
since 1957, they greatly simplify the computing methods
and at the same time widen the scope of problems to be
investigated. The static eloctrointe-grators have al-
ready been used for computing diffusion, of neutrons as
L)
well as for solving nonlinear problems pertaining to the
theories of heat conductivity and hydrodynamics (Figure
Card 112 2). The article also mentions two additonal SEI mode

the first being practically an electric analog of D.
V. Budrin's hydrostatic integrator and the second an
,~SEI with an ohmic-type, movinE computor devicd (Figures
3 and-4). The latter has a Creat advantage as it can
make calculations by dividing the space-time component
into as many elements as desired. In addition to this,
the SEI with an ohmic-type moving computor device has
small dimensions, its only bad point being the neces-
sity to make intermediate entries. The article also
mentions the Problemnays. laboratoriya kafedry obshchey

TITLE: On the aerodynamical theory of the gaseous tongue of flame

121180 (V sb. "3-.,re Vaes..soveshchaniye po teorii goreniya. v. 2".
Moscow, 1960, 219-227)
TMi The authors present a brief survey on Investigations of the aero-
dynamical theory of the gaseous tongue of flame based on the idea of an infinite
reaction rate of combustion. This assumption leads to a scheme of diffusion
combustion as in.the case of both unmixed gases'and homogeneous mixtures. The
latter! 6ase is Investigated in. detail. If for the case. of combustion of unmixed
gases the equation system is complete, since the flame front Is found from the
stoichiometric relation of the,flows of the reacting-,oomponents, an additional
assumption on the position of the flame front is necessary for the flame tongue
of a homogeneous mixture. In oiqer to solve this problem, the condition of the
gas-dynamic scheme.of the flame front Is taken as an oblique heat discontinuity.
In such a scheme thi whole range of flame tongue is replaced by the surface of

assumed,thati the solution sought-for,is taking-plaee at-the maximum,deviation

oharatterlalle (ratio-of-the thermal egfoot to the initial enthalpy) of the order
5-7 the magn itude of 0~1 is near to 70 . In this case the angle of slope of the
flame front does not depend on the flow velocity and'only slightly depends on the
heat releasq characteristic. A comparison of these results with the test data
shows that.actually, as-this follows also from the "aerodynamical scheme", a
certain warming-up of the fres'n mixture, its expansiori and a deviation of the
lines of the flow to the flame fr nt can be always observed. Owing to this a

TITLE: Optical Modelling of Radiant Heat Exchange in Furnaces
PERIODICALt Teploenergetika, 1961, No.2, pp. 67-71
TEXT: The general theory of similarity requires than an
optical model should fulfil the three conditions: geometrical
similarity; identity of optical properties of surfaces and media;
and similarity in the distribution of radiation sources. A special
feature of the optical modelling method developed in the Kazakh
University is that it avoids fulfilling the third condition by
determining on the model a system of optical-geometrical parameters.
When these are known it is possible to calculate the distribution
of radiant fluxes with an arbitrary distribution of sources in the
system in which only the first two conditions need be observed.
Thus the technique of op'(,4ical modelling is greatly simplified.
The object of the present article is to direct attention to this
method which is still not sufficiently widely used. Accordingly,

Optical Modelling of Radiant Heat Exchange in Furnaces
,the essentials of the method are described and practical results are
given, In optical modelling of radiant heat exchange the radiant
fluxes are so low that the temperature factor does not enter into
the experiment. The method is nevertheless applicable to studies of
furnaces where heat fluxes and temperatures are high, because the
equations of radiant heat exchange are the same whatever the energy
or spectral composition of' the radial fluxes. The temperature
distribution is determined in the model by the self-radiation
distribution both in the volume and on the walls. From this the
temperature distribution is calculated on the basis of the Stefan-
Boltzmann law if an integral radiation is modelled; or by Wien's
formula if the nature of radiation is being studied from separate
spectral bands. The present article considers only integral
radiation and assumes that the radiating walls and media have the
properties of grey diffuse radiating and absorbing bodies. In
modelling, the object is sub-divided into a mimber of surface and
volume isothermal zones. The optical properties of the surface
zones are characterised by the mean absorption capacity and those

of the volumetric zones by the attenuation factor of the medium.
Modelling consists in constructing a geometrically similar system
of surfaces having optical properties identical with the original
and a similar distribution of isothermal zones. The attenuating
properties required of the medium are discussed. The method is
based on the principlar of' additivity of radiant fluxes which makes
it possible to determine the optical-geometrical parameters of the
model. If only one surface zone in the model is radiating, the
incident flux on different elements of surface can be measured.
These incident fluxes will be both those received by direct but
attenuated radiation and those reflected from other surfaces. By
successively making one zone luminous after another and measuring
the resultant incident fluxes, dimensionless absorption factors may
be determined for various elements considered. Then the results
are summated to determiner the flux density incident on any zone
from all the other zones. Simple formulae are derived and it is
dhown that by tests on a single model and simple calculations it is
possibla to solve a range of problems. The study of radiant hoat

exchange in the chamber of a stoker-fired furnace by optical
modelling is then considered. A transparent plastic model in the
shape of a cube of side 15 cm inside contained thin metal walls
painted matt black. In one of the walls there were 64. holes which
were used to measure the incident radiation. Various difficulties
that arise in malting the measurements are described. Experience
has shown that they can be largely overcome if a thin layer of
translucent celluloid with a matt surface is placed between the
inner wall of the model and the outer. As incident radiation may
be at any angle, the sensitivity of the pick-up should not depend
on the angle of incidence, This condition is largely satisfied by
a germanium photodiode operating as a valve. This photodiodo has
maximum sensitivity In the infrared where the absorbing capacity of
ordinary water 13 fairly great. Accordingly water may be used as
the attenuating medium in the model. The problem of modelling self-
radiation of the medium filling the volume is overcome by having a
single source of radiationg moving it from place to place and
summating the results. The particular model described was divided

into 61f zones. The radiating element was a cube of transparent
plasticp corresponding accurately to the size of the zone. The
cube contained a small lamp; it was filled with water and the
outside was covered with translucent celluloid. To check the
experimental procedure a model was used to study the radiant output
of a cylindrical source for which a method of calculation exists.

accuracy could easily be increased to 2 W The burning layer of
fuel was represented by a flat illuminator with uniformly luminous
matt surface. The measurements were made and for each unit of
sub-division a table of 64. local values of absorption factor was
drawn up. There was no need to make 64 such tables; because of
the symmetry of the model only 16 were required. The tables were
then used to calculate absorption factors from formulae (3) and the
distribution of incident; fluxes on the walls of the model was
determined for the case of a uniformly radiant medium and a fuel
layer. Examples of radiant flux distribution of the model were
plotted. Attention *.ias recently been drawn to radiation

back from the screen tubes. Accordingly the difference between
the actual operating conclitions of screens and those which are
usually assumed was investigated. A study was made of the
influence of the degree of blackness of the screen tubes on the
heat exchange conditions in furnaces. The method of setting up
:the model to do this is briefly described and comparative data for
tubes,with absorption factors of 0.6 and 0.9 shows that alteration
of the degree of blackness of the screen tubes has no important
influence on the radiant heat exchange in the case considered.
Results obtained in tests on the optical model with almost black

tubes and agreement was good. Ways in which the procedure may be
further developed are discussed and it is recommended as a useful
aid in calculations of beat exchange.

TITLE: Flow of gas around a plate with burning surface
PERIODICAL: Inzhenerno-fizicheakiy zhurnall v- 4, no. 3t 1961, 39-45
TEM The authors investigated the flow of a homogeneous compressed gas
around a burning plate. The variation in velocity, temperaturep and concen-
tration profiles along the plate was considered in the approximation ob-
tained. The studies were devoted mainly to laminar flow in the boundary
layer along the plate. In order to find the "quasi-progreasing" profiles u,
T, and c, solutions of transcendental equations of the heat theory of com-
bustion are used, which are reduced to the boundary conditions on the Bur-
fave of reaction. For this purpose# the boundary conditions of the surface
of the plate are transformed into the form usually employed in problems of
the thermal conditions of combustion. The transcendental equation (8) from

in a +-19, plane. Figs.'l and 2 illustrate typical results of these solu-
tions. The schematic representation of the graphically determined results
(Fig. 1) gives a clear picture of the dependence of the surface temperature
on the velocity of the incoming flow, when the parameters of heat exchange
A and of the length x are given and various values of heat generation
4>3 3>.92>'91 - 0 are ass=ed (B - point of ignition, n-point of extinction,
A and T - adiabatic and heat exchange, reopectively). When the values of
heat generation are given for two velocities of the incoming flow, the tem-
perat'ure variation along the burning plate shows (Fig. 2) that ignition of
the plate takes place, if any at a certain distance from the front edge of
the plate. The values of temperature 0 and of concentration cw determined
by a graphical solution of Eq. (8) accowrding to the coordinate xf make it
possible to construct the profiles of u, T, and c in the cross sections of
the flow if all the other parameters are given. Fig- 3 shows the profiles
for two cross sections (before and after ignition) as an example of such
a construction. It was further shown that the state before ignition belongs
to a kinetic combustion according to the nature of the process, and after
ignition to the diffusion zone, This result is typical of a hysteretic

process of an exothermic heterogeneous reaction if combustion takes place
only in the vicinity of the diffusion zone. The authors point out that, in
principle the obtained solution may be generalized to the case of a burning
plate with a turbulent boundary layer. More details about this case will
be published in a special paper. From- the prac-tical standpoint, the present
problem has to be treated as one of the limiting schemes of ignition and
burning of bodies which move at high speed through the atmosphere. Mention
is made of Dorodnitsyn, Ya. B. Zel'dovich. There are 3 figures and 7 refer-

TEXT: The experimental arrangement shown in Fig. I was used to study the
turbulent mixing of a gas jet with a gas flow of different temperature.
The limits vith~n which the parameters of gas jet and Cas"flow were varied,
are listed in Table 1. In their experiments, the authors determined the
velocity head and the temperature distribution along the axis and over the
cross section. The velocity head was measured with a Pitot tube 0.8 mm in
diameter, and the temperature was determined by means of a platinum -
platinum rhodium thermocouple. The turbulence of the gas jet and of the Eas.
flow at the exit section of the nozzle was measur6d by means of !in

computed from measurenento of Qu2 and AT. As characteristics for the

TMT: The authors discuss some methods for calculating homogenized-core

due to absorber redistribution in the core. By usinLr the integrators
described in earlier papers (Vulis, Kost:ritsa, Tr. KazGU# Alma-Ata, 1959;

1959), some characteristic functions such as the fuel density distribution
and the neutron density distribution are determined. The equations for a
reactor with nonuniformly distributed fuel are difficult to solve in ase or
multiEroup approximation but easy by simulation methods. A one-dimen3ional
static integrator designed for solving heat- conduc tion- type aciiiationa withcon-
otant fnotors is described and discussed. In principle, reactor simulation
needs two integ;:,ators: the first one for neutron moderation whose results

TEXT: Investigations were carr ied out on the larninar flow of a compressible gas stream emctging from a
nozzle mounted at the apex of a right cone and forming a jet spreading along the cone surface. The reactions
taking place are assumed to be of endothermic character. For calculation of the velocity profile, tc mperature
and concentration of the reacting gas, the motion in the boundary layer is assumed to be a flow in a semi -
confined source-jet, the cone surface to bo non-conducting, and its rcactivity-to vary with the distance
from the apex. The system of differential equations thus obtained is integrated by means of Daronitsyn
variables, Solution of this problem permitted determination of the relationship between the hydrodynamics
of a compressible gas stream and the combustion theory; results give a qualitative picture of the interaction
of a burning gas and the surface of a body, rhcre are 7 references.

in a magnetic field normal to-the surface which constricts the flow to a semi-
bounded space *-__TM magnetic field value restricts the Reynolds number values to
.much less than unity. The usual equations of motion are-solved by use of slmilari-_
~ty transformations and Iterative approximations whom the zero order solution is
1hat for the nonconducting fluid. It is shown that the velocity profile is given-
Iuite -accurately--by -a- single -1teration.- -The- s6lu lons am plotted for several

ABSTRACT: One of the characteristics of MHD flows of a low-temperature plasma iswell-
defined temperature dependence of condu 'ctivity. 71i; Tonlinearity due to this may load to
an ,unbiguity of steady states and to unique hysteresis effects. For MIID flows such effects
were detected elsewhere In the course of numerical calculations of hypersonic motions. An
elementary theory of the problem for Couette now has been published. Inasmuch as the
nature of Me phenomena investigated, generally spealdng, Is not related to a specific type
of flow, It is natural to assume that an analogous manitestation of nonlinearity Is found in
cases other than thofle studied in relation to hypersonic motions. From this viewpoint,
the present authors Investigate the practically important case of theflow of a conducting gas

dimensional steady-state flow at low values of the magnetic Reynolds number and Hall
parameter. The stucty Is restricted to a general, primarily qualitative statement of the
problem and some examples which allow the presentation of the final results in a simple
form. Detailed data for specific cases may be obtained by means of nwmerical caltvilations,
