Kavrayokiy (Ref.9 Footnote on P. 48) suggested a now method of sun sighting. It was based on the coincidence,of the coose wires,with the intersecting (or contact) points of the four sun pictures formed by a special prism sight in the field of view of the telescope (Fig. 1). V. V. Kayrayokiy studied such a sight theoretically and made a model of it (Fig. 2). In 1949, an experimental type was made'according ~to this model'by the sluzhba vremeni (Time Bervice)of the ToXIIG*iK. It proved to be complicated in production and inconvenient In operation. In 1957, V.7. Kavrayskiy's scheme was realized in a better construction by F. D. Rabinoiich. This sight is briefly described and the-toot results of the experimental type made in 1957 are given.

The. value and position of the current.. Card ACCESSION NR: AP4038623 maximum and their temperature dependence (positive or negative) are determined 'by the conditions of production of the tunnel diode. This holds true in both cases: (a) a strong degeneration and (b) a substantial blurring of the function of carrier distribution. The new formulas are claimed, to be in good agreement with experi-, mental data. "In conclusion, the authors consider it their pleasant duty to thank E. 1.

In the case of counterflow the problem must be,formulated as follows: On the one side of the heat exchange surface theliquid 1 flows continuously in te direct- ion of the negative x-axis. This liquid enters the apparatus through that section having the coordinate x-1, the temperature in this section being constat and equal to t' - 0.

'An Experimental Investigation of the Heat Transfer Process Between a Pulsating Gas Flow and Solid Particles Suspended in It PERIODICAL: Inzhenerno-fizicheskiy,zhurnal, 1959, Nr 9, PP 30-37 (USSR) ABSTRACT: A number of writers dealt with the problem of intensification of,heat_.. transfer: I.T. Ellperin, V.P.

Hot air.heated to 130 IL500C served as a gas whose,:-'low was periodically interrupted by a pulsator, which led to pulsations of its velocity. The grains of rye were made to move in this pulsating air flow. It has been found that the duration of particle staying in a tube was considerably.-longer for the caselof a pulsating flow than in the stationary flow; this is shown by Figure 1 and Formula 5. On the other hand, the coefficient of heat transfer de- creases with an increase In the number of pulsations of the air flow, as shown by Figure 2. However, the resulting effect of pulsations.,on Card 1/2 the effectiveness of heat transfer is positive, as shows Figure 3, and 06563 SOV/170-59-9-4/18 An Experimental Investigation of the Heat Transfer Process Between a Pulsating Gas Flow and Solid Particles Suspended in It. the effectiveness of this process can be raised by a fac Itor of 3 or.4 in comparison with heat transfer in a stationary flow.

TITLE: The Calculation of Driving Pressures and Natural Circulation in Steam Boilers and Evaporators PERIODICAL: Inzhenerno-fizicheskly zhurnal, 1959, Nr 7, pp 67 74 (USSR) ABSTRACT:. In view of the fact that the TsKTI.method of.calculating circulation-does not take into account a number of factors affecting this~process, an attempt is made-to approach the problem of natural circulation from the standpoint based on the basic equations of heat transfer (Formulae I and la). The solutions of these equations leae. to Formulae.8 and 9 expressing the values of driving pressures P divided by the height of the liquid column H for thelcases of direct flow and counterflow respectively. The generalized formula 20 includes all the factors affecting the magnitude of the driving pressure, i.e.: the ratio of specific gravities,~circula-: tion ratio, and f3,-factor, taking care of thetemperature of heat carriers at the ends of the heat transfer surface.

Session on Convective Heat Transfer PERIODICAL.- Inzhenemo-flzicheskiy zhurnal, 1959, Nr 9, pp 111-112 (USSR) ABSTRACT,- A session on convective heat transfer took place in the Leningrad House of Scientists from 15 to 20 June 1959. It was convened by the Commission on High-Pressure Steam., the Scientific Technical Council of the Leningrad Sovnarkhoz and TsKTI. About 70 reports were delivered in the Conference. The reports of M 'A. Styrikovich (ENIN) and V.Ye. Doroshchuk (VTI) dealt with the problems of the crisis of water boiling. Their conclusions were similar to those of A.P. Ornatskly (Kiyev Polytechnic Institute). Two , reports, by L D. Berman (VTI) and V.A. Rachko (TsKTI), dealt with the problem of determining the heat transfer.coefficients of the steam-air mixture in vacuum. Two reports from ENIN,,delivered by Z.L. Miropol'skiy and M.Ye. Shitsman were concerned with heat emission of water during its, cooling In the near-critical region. The reports by N.V. Tarasova (VTI) and A.P. Orrat*kiy presented the results of investigations of hydraulics Card 1/2 resist&nce during the boiling of underheated water in tubes. N.I.

Novikov (MIFI) expounded the theory of, thermodynamic similarity in which viscosity and heat conductivity were con-, sidered not as constant quantities but as thermodynamic variables. A.I. Leont'yev reported on an investigation of the heat transfer processes at forced pulsations of air pressure in a short tube, V.P. Matusevich reported on the theoretical solution of the,heat transfer problem in a head point of blunted bodies colliding with a gas stream. I.G.

In his earlier papers (Refs. 2, 3, 4) he has shown that heat exchange in a recuperative apparatu:c~ is expressed by partial differential equation of second order. The problems of heat exchange in a layer can be formulated on the following condition@; 1) The temperature gradient within the particla~ forming the layer is negligible. This can be attained already with 2) The amount of heat mutually delivered by ~ha particles by contact heat exchange is negligible compared to the amount of hoat exchanged by the particles with the liquid flowing through their layer.

Iquation (2) is-solved by the Laplace-Carson transform yielding formul: (8). From this formula the individual sp*cialcasee can be obtained according to the dependence of the internal source on coordinate and,tize. The following cases are investigated: Caee1;:Her~, the internal source does not depend on coordinate and time (q - const.) and formula (12) is obtained for V. Came 2: 1 The internal source is a function of temperature. Two Vl:ndb of functions are Investi gated: q w a(t"-t ) where a and t are certain constant quantities, and q - a(t"-btt~1111 0 0 where a and b are constant. The formula@ (19) and (24) are obtained. If q a 0, a - 0 and b - 0 in assumed, formula (26) is obtained for the temperature distribution in ~a layer without internal sources. In the case in which the heat carriers move crosswise at.900, formula (27) in obtained. Basing on the@* results and on some additional assumptione,the heat exchange in a moving layer of disperse material in the case of t 'ranoverse blowing with a gas at the immovable layer can be Investiga- ted.
