Then following the same assumptions as were made in deriving exp!t,essions for the thermal conductivity of Card 3/9 the gases (Ref 8). using Eq (5) in which X gd is the 69322 S/147/6O/0Oo/O3-./o.11/OjL8 E022/E5,75 On the Mechanism of tho Process of Heat- and Mass-Trartsfer During Evaporation Cooling of Strongly Heated Surfaces coefficient of heat conduction of the gas when diffusion is present, M is the molecular weight and 11 is the viscosity of ~he gas and relating this with th correspo:)nding heat conduction coefficient without diffusion, % (Eq 6), it is found that the two coo?fficient;sgdiffer by the pressure ratio p r/pc. The partial pressure p of the gas varies across the boundary layer and ther´┐Żfore an expression for the mean valLue of tho heat conduction coefficient ~ is Adss of introduced (Eqs 8 and 9), 6 being the thick e the boundary layer. Employing now the Stefan relation, Eq (10), for the diffusive process, (gd being the diffusion fJux and k the coefficient of diffusion), integrating it on thepassumption that k =: const and combining the result with Eq (9), thR relation Eq (12) is obtained which also can be expressed by Card 4/9 Eq (14).

The experimental data of H. Seifert en al. (Ref 12) agree with these graphs. When no diff~ttsion takes place heat transfer from hot gases to a vrall is usually determined by the Nusselt number Nu its given by Eqs (15) and (16) fDr the external and internal flows respectively. To account for the effoct of diffusion on the heat transfer, Eq (14) can be used in the manner shown in Eq (17), this result* in Eqs (19) and (20) instead of Eqs (15) Card 5/9 and (16).

For higher partial-pressures and especially when liquid temperatures are near the boiling point of the given pressure of' the mixture, it is necessary to use StefanIs equation of diffusion (Eq 24) instead of that of Fik (Eq 2:1), which eventually leads to Eq (26) for the external and Eq (27) for the internal flows. The diffusive Nunselt number is based.on the tel3lperature of the liquid and the other number on the temperature of the gases,. To determine the temperature of the liquid the analysis starts with Eqs (28) and (30) which together lead to Eq (32), so that the temperature of the liquid may lbo found if the relation between the partial pressure of the diffusing liquid is known as a function. of the temperature of the liquid. Fig 3 shows the Card 6/ 9 relationship between the temperature of the liquid (t A 69322 S/147/60/000/01/011/018 E022/E535 On the Mechanism of the Process of Heat- and Mass-Transfer During Evaporation Cooling of Strongly Heated Surfaces and the temperature of the gases outside the boundary layer (t go ) as determined by Eq (32) for various pressure conditions. The few experimental data available are also introduced in the figure, viz. o - from D. I. Polishchuk (Ref 13) and A from G. R. Kinney (Refs 14 and 15). The agreement is considered good. Finally the amount of the evaporated liquid per unit area and unit time is determined, Eq (34), and the effectiveness of the cooling is then analysed. This is defined as the relative specific evaporation of the liquid gd/g9It i.e. the ratio of the evaporaLed liquid per unit area of the cooled surface to the rate of flow of 1'.he gases per unit area normal to the direction of the flow. Its value is given by Eq (35), and this is plotted in Fig 4 (graphs 1, 2 and 3) for the case that wator is being evaporated from the internal surface Card 7/9 of the tube in hot air.

The small deviations from each other of the Crocco graphs (5 with diffusion, 6 without diffusion) seem to indicate that the factors considered by him do not influence greatly the heat transfer rates, but the larj;e difference between the curves 1 and 7, the former into account the variation of the heat conduction and the latter neglecting it, indicate clearly the strong effect, of this factor on the heat- and mass- transfer.

TITLE: Heat"I and Xass Exchange4n Cooling by Evaporation of Surhoes Heated Fo -High Temperatures /C PERIODICAL: Inishenerno-fizicheskiy zhurnal, 1960, Vol- 3, No, 5, pp. 31 - 39 TEXT: The thernal flux of hot gases to the surface of a solid. coated with a thin liquid film is accompanied by a vapor current of o:pposite direction. The presence of a diffusion current of a direction opposite to that of the heat flux considerably modifies the thermal coz,,iuotivity of the medium ir, the boundary layer. The prooesses of heat and, mass ex- change occur mainly in the boundary layer. The molecules of the diffus- ing substance shift between the molecules of the hot gas in the direo- tion leading away from tho wall and cause a specific current Df the diffusing substance. It is assumed that this ourrentp which is inverse to the heat flui: and gradually heated$ does not participate in the heat transfer of gasete to the wall. The last process is caused only by the Card 1/3 Heat and Mass Exchange in Cooling by S/170/60/003/005/i:165/017 Evaporation of Surfaces Heated to High B012/BO56 Temperatures gas molsouleeg the concentration of which decreases continuou. Ly during their approach to the wall. The oriterial equations (11') ~nd (18) for heat exchange as well as (24) and (25) for mass exchange are dorived. These equations take account of the interaction of heat and vapor currents througb the boundary layer and their influence upon the heat- transfer and diffusion coefficientag as well as of the Stefan ftow. Formula (28) is derived, from which it may be seen that the teaperature of the evaporating liquid does not depend on the Re-number of ~,.he flow round the wall. Fig- 3 shows the curves calculated from formula (28) for the relation between the temperaturesof the liquid and the gas in the case in whic;h the water evaporates in the air-current, and the ex- perimental data are given. From this figure it may be seen that the ex- perimental data agree with calculated ones. Formula (30) is wx,:Ltten down for determining the efficiency of cooling.

The use of swirling gas flow4; has not resulted in significant improvement in convective heat transfer, whilst liquids present the problem of bulk transportation with a consequent loss of energy. The author carried out an experimental study of heat exchange properties of two-phase swirling flow. He succeeded in planting a film of water droplets on the internal wall of a heated vertical porcelain pipe (inside diameter 40 nim, length 1200 mm) carrying a sw:irling stream of air. Analysis of the results led Card 1/3 The use of swirling two-phase flow... S/024/62/000/0()1/002/013 E-195/r-135 to the following conclusions. 1) By injecting liquid into a swirling flow of gazi it is possible to produce thin, continuous and stable liquid films on the internal surface of a cylindrical pipe 2) By varying, the Reynolds number within the range 2 x 104 - 8 x 104 in the swirling flow, the Nusselt diffusion criterion can be increased to double that of a non-swirling flow; this indicates a considerable intensification of heat and mass transfer processes. 3) A heat-exchange coefficient of the order 21100-2900 kcaI/m2/hz'/OC was obtained for a heat-flow rate of 75000 kcal/m2/hr in this range of Reynolds number; this is 40-70 times higher than that for non-swirling flow and 8-20 times greater than that for a single-phase swirling flow: the total resistance, however, increases by a factor of 7. 4) Under comparable teaiperature and energy loss conditions, the use of single-phase sivirling flow will result in a net gain of 2-2.5 times in heat transfer rate in comparison with non-swirling flow. The introduction of two-phase swirling flow would produce an additional gain of :5-20 times that of swirling one-phase floif Finally, the author suggests that there is considerable scope Card 2/3 The use of swirling two-phase ...

The Packard-Varian. method consists of the following. The specimen, which has a relaxatMon time of the order of a iiecondt is magnetized by a sufficiently large auxiliary field H 0 t perpendicular to the weak measured field h 0 . When the auxiliary field is suddenly switch~ad off, the magnetization vector M prectesses about h0 with an angular velocity w = yh 0 . The coefficient y is practically equal to the gyromagnetic ratio of the nuclei under investigation. In practice, the most Cardl/5 important cases are those In which transient processes 80125: S/141/59/002/06/006/024 E012~11 Phenomenological rheory of Free Prece s OA104f the Magnetic Moments of Atomic Nuclei associated with the switching-off of the auxiliary field are damped out during a period of time which is considerably smaller than the-relaxation time for the system of nuclear spins. In that case, the relation betwevn them magirettzation vec*or M and-the field H is given 'by Eq (1), which describes the motion of the magnetization voctor during the transient process. After the transient process is completed and when only the field h0 remains, the magnetization vector precess&s freely, the appropriate equation being Eq (2). The latter equation was obtained in the previous paper by one of the present authors (Ref 12). When the transverse and longitudinal relaxation times are equal T = T.L 1 11 the solution of;'Eq (2) is given by Eq (3)- Such an approach to the problem enables one to consider independently the effect of the switching-off of the auxiliary field on the initial precession amplitude anc~ Car,12/5 V 80125 S/l1*l/59/002/o6/oo6/o24 Phenomenological Theoryof Free Prefieasflalof the Magnetic Moments of Atomic Nuclei the characteristics of the damping of tho free precession signal., It is shown that when the frequency of the tran- sient process a) is considerably greater than the precession frequency in the measured field h 0 , the transitint process has practically no effect on the initial amplitude of the precession signal even in the absence. of datnpkag. When the frequency of the transient process w is sivaller than the precession frequency, the transient pro.c;es;s will have no effect on the initial amplitude of the precession signal only if it is heavily damped. In particular, if the- aux-t1lary Tield is aperiodi.c (w = 0) , the da=ping-constant should be considerably greater than the precession frequency (Eq 6).

The differential stability criteria for Eqs (1) were found by a number of authors (Refs 1-3). Cardl/4 In the following an attempt is made to determine the 80132 S/141/59/002/06/014/024 EJ?2 UP Relay-type Control overall Stability of the Equilibrium- ate o Systems criteria of the overall stability of the system. The method employed in the analysis is similax to that of Malkin (Ref 5). Further, in the analysis it is assumed that the system fulfils the conditions defined by Sqs (5)- It is shown that Eqj!i (1) can be written as Eqs (6), where X and F are deftned by Eqs (7). The Lyapunov fumetion V for Eqs (6) and (7) is constructed. This is defined by Eqs (24), where the components of the functions are expressed by Eqs (20) and (21). In its final form the Lyapunov function can be written as Eq (28). The stability criteria can now be defirted on the basis of the Lyapunov theorem. This states that if all the roots of the characteristic equation: n dxi/dt = F-pisxs (i = 1, eoe, n) (29) 5=1 have negative real parts, then independently of W Card 2/4 (Eqs 22). there exIsts only one V, of the same order Ll
