TEXT- Dry seeds of the radicsensitive A. fistulosum and of
the radiostable N. damascena were investigated, From a table,
it is evident that the A. fistulosum is 9 tin-es more sensitive
to X-rays than the N. damascena. A comparison of the number of
aberrations in the seeds which took part in the flight with con-
trol seeds showed no difference whatsoever in the frequency of
chromosome rearrangements in the seeds under investigation,
This negative result, obtained %ith dry seeds, made it necessary
to conduct tests with growing seeds, These tests showed that

space-flight conditions have a Stimulating effect on the growth
of both species; this stimulating effect is mcre noticeable in
the radiostable species N. damal3cena. In general, dry seeds are
fairly stable to ionizing radiation; thus, the seeds of A. fiatu-
losum have to be irradiated by a dose of 250 - 500 r, and those
of N. damascena by several thoutiands of r6ntgen in order to
observe an actual increase in chromosome rearrangements. The
authors arrive at the conclusion that the increase in the growth
of the seeds cannot be related -;o stimulating radiation doses,
as the stimulating effect is stronger in the radiostable species
N. damascena and weaker in the radiosensitive species A. fistu-
losum, If the observed effect on the N. damaecena would have
been due to radiation, the indicated dose would have caused
chromosome aberrations in the A. fistulosum to3. This was, how-
ever, not observed. It is evident that the reason for the ob-
served effect should be sought :.n other factors which are active
in apace.-flight.--factore which are thoroughly unlike those

ABSTRACTs The object of the present work is to find an approximative
equation for the field of velocity and the temperatures in the
case of a laminar current in tubes with liquids which are capable
of dripping in consideration of the changing of the viscosity of
the liquid with respect to temperature. This investigation was under-
taken for the purpose of showing that the modification of the
physical characteristics of liquids with temperature is one of the
most important causes of the divergence between theoretical solu-
tions and experimental results. At first the equations for the
motion and heat transfer in the boundary layer of cylindrically
shaped tubes are written down. The existing solutions of this
system of equations apply only to the case ofp& - const, which
leads to more or less grave errors. Therefore, the attempt was
made to find an approximated solution for this system of equations
for the case that the change of the viscosityttin connection with
temperature is taken into account. The method of successive ap-
Card 1/2 proximaticn by SHVETS-TARGA was selected for this purpose. At

first, temperature distribution in first approximation for the
radial cross section of the boundary layer of the tube was found.
Next, the temperature dependence of the viscosity coefficient of the
liquid capable of dripping is showr- with the required accuracy in
form of a series. In practice the jolynomial of the third, or
even only of the second degree will suffice. After transformation
and integration the equation for the velocity of the flux in the
case of a nonisothermal motion in the tube is obtained. Next# the
formula for the average velocity of' the cross section is given,
after which only the domain adjoining the wall is investigated
and the equation is found in which one of the multiplicands taken
the influence exercised by the non-isothermal course of the
current into account. In the case of the second initial equation
the case of an infinite distance from the wall As dealt with and
an ordinary differential equation is obtained. The average value

ABSTRACT Though the theory an the analogvs phenomena on the oocasion of
the transmission of momenta and 4nergy in relation to the
quantitative partf which was for the first time mentioned by
Reynoldsq was named the hydrodynamic theory of heat exchange,
the author believes that it ought to be called the theory of
thermofriotion analogy. The reason given for this is that the
main task of this theory in the discovery out of a direct
relation between the hydrodynamic and the heat exchange
characteristics. Existing methods are not complete and re-
sults differ up to 100 % and more. A much more simple and
safe way is shown here. At first the universal relation bet-
ween Nu and Re is deduced:
Nu I c Re 9-1 ..... dimension/less

of .... coefficient of surface friction, dimensionless.
The value here acts as second parameter. The determina-
tion of this V%-Ivcj-ives the solution. Since a laminary sub
layer exists in the turbulent boundary layer the value of this
parameter can be assumed to differ only little from that of the
laminary boundary layer. This value can be found analytically
fan,,the laminary boundary layer. It is derived here and the
basic equation reads as follows:
NU cfRe Pr 1/3-
Now this formula for the different cases of a turbulent flow
is applied and it is shown that the results obtained agree
with those of the experiments. The same is shown to be the
case with motions of liquids in tubes as well as with the
motions of a compressed gas. The last mentioned formula
remains the same for gases. (With 2 tables)

ABSTRACT: Non-stationary convective heat transfer is met with in
many branches of teohnology. The non-stationarity may be
associated with the process i-~self or with a transition
state from one stationary process to another. In spite
of the major practical importance of non-stationary thermal
convection, there are no theoretical or experimental data
on the subject at the present time. The absence of such
data is due to the great mathematical difficulties involved
in an accurate solution of the preDlem. This is thq reason
why in calculations of heat-transfer processes in which
speeds and temperatures are functions of time, one has
been forced to use forn-uiae which describe stationary
convection assuming that these formulae will also apply
when the speeds and temperatures which enter into them
vary with time. However, there are no data in the literature
which would indicate the range of applicability of these
Cardl/5 formulae. The present paper is an attempt to obtain an

ABSTRACT: The results obtained previously in the paper cited in
reference 1 are :ftfther developed, made more
precise and compareC with experimental aata. In order to
check furmula (4) specifying the heat flow between the liquid
and the wall of the tube the protlem of the influence of the
direction of a heat flow-is inveetigated. The influence of the
non-isothermic courset on the-hydraulic resistance is then
examined. It is shown that formula (a)-is a generalization of
formula (9) establisl~ed by Poiserille (Puazeyl~)-for the case
of a non-isothermal motion. The relative of I coefficient of
hydraulic drag) in tEe case of a ehange in direction of the
heat flow was calcultted. Water was used as fluid medium and
for the calculation of the coeff!.cient of the non-isothermicity

ABSTRACT: Proceeding from the not o'.' equations (1) for heat transfer under
arbitrary conditions, the author derives equ%tions (5) and (6) for
quations are considered to be
equations (2) and (3). Thisse two
o;
sufficiently accurate solutions (1). For practical purposes#
however, they proved to bij not very useful. The author suggests
to derive less complicated and thus more useful approximate solutions.
A correction of the solut:.on for steady conditions leads to formu-
la (9) for nonst*ady cond:.tions, which has the form of the ordinary
Bernoulli differential equation. Next, formula (11) for the resis-
tance coefficient is deduned herefrom. A similar way is chosonfor
equation (6) for the heat exchange. Thus, formula (20) is obtained
which is used to compute Ithe Stanton number. There are 5 references,

PERIODICALi Inzhenerno-fizicheskiy zhurnaL, 1959, Nr 6, PP 111-115 (USSR)
ABSTRACT: In order to investigate the effect of the initial section of a pipe
on hydraulic resistance, the author writes down equations of mass
and moment conservation in dimensionless form. He makes use of the
results of two experimental findings: 1. One of them expresses the
law of velocity distribution over the cross section of a boundary
layur, and 2. The second is the statement that the character of
development of a boundary layer in the initial section of a pipe
is similar to the character of development of a boundary layer,
-when a liquid flows around flat surfaces. The boundary conditions
are obtained for the distribu,;ion of surface tension, af, and the
coefficient of hydraulic resiotance along the length of a pipe 9 9
and the problem is reduced to a system of six algebraic equations.

ABSTRACT: Grets (Ref 1) has given a solution of the problem of
convective~heat transfer in the case of laminar flow
of liquidsTin stabilized sections of tub Lz6 The
differential equati3n for the heat transfer, which does
not take into account radiative terms, is given by
Eq (1), where T(r, z) is the absolute temperature of
the liquid, r and z are the radial and axial
cylindrical coordinates, a is the reduced thermal
conductivity (i.e. the ra-,io of the thermal conductivity
and the product of the specific heat and the density of
the medium), and ir(r) is the velocity of the liquid.
Grets has found solutions of Eq (1) for two cases,
namely. when the volocity distribution is parabolic
(Eq (2)), and when it is .-onstant (Eq (3)), However,
Cal',l 114 it can be shown (R,,-f 2) t:iat provided the condition

2RP/z e, 15 is satisfied (and it is satisfied in many
practical cases), tte two solutions are almost identical.
In this condition 11 = 2UR/a. The present author assumes
that this condition is satisfied and writes down the
energy equation in the form given by Eq (5), in which
radiation effects a--' e included in the form of the second
term on the right-hand side o` Eq (5). In this
equation, p, c and X are the density, specific heat
and thermal conductivity of the liquid, k = 3a/2, and
T is defined by the fourth equation on p 184 in which
D = 2R is the diameter of the tube, a is Stefan's
constant, and n is the refractive index. Eq (5) is
then linearized using the substitution given by Eq (6),
where Tm is given by Eq (7) and To and Tj are the
temDeratures of thE liquid at -r;he input and of the walls
of ihe tube respectively, The equations are then trans-
formed into a dimensionless system of coordinates, which
is defined by the relations immediately above Eq (8). When

is the same as that obtained by Grets for pure?y convective
heat transfer. The total heat flux (I passing through
the walls of the tube (per unit area) can be found from
Eq (11) and is given by Eq (12). An important consequence
of EqS (10) and (12'i is the fact that when radiative
corrections are brought in, the temperature drop and the
quantity of heat gii-en up by the medium change more i b.""

functional interrelation between V, T 0 , qoj T19 and q, is sought. First,
the heating of the body by radiation without convection is investigated. In
this case, only the interrelation betmeen q 0, T1 and q, need be found.
The formula (1) for thermal conductivity is written down, and it is shown
that consideration of heat transfer by radiation leads to the nonlinear
boundary condition (5). As a concrete example, the heating of a plane,
rather thick wall by radiation is investigated. The thickness of the wall
makes it DOssible to regard it as a gemi-limited body during the time of
investigation. If internal sources for heat production should be lacking,
the differential equation (6) may be written down, for which the boundary
conditions (7), (8), and (9) are given. Assuming formula (13) the boundary
condition (8) is linearized, and formulas (17), (18), (19), and (20), which
determine the required interrelation between q 0, T1,and q,, are derived.
Next, the convective heat exchange 13 investigated in consideration of
radiation. For this case, the approx~-mate formula (24) is recommended,
where the nonlinear boundary condition ~5~ becomes formula (25)- In the
present case, the solution of equation 1 makes it possible to determine
the interrelation between q,, T19 qos and T*. a - a(V) is agsumed to be
