In-ta mashinoved. i avtomatiki AN UkrSSR, 1957, Vol 6, pp 75-82 ABSTRACT: The authors present the solutioq of a problem on thermal conductivity for an infinite strip iT1 which the temperature of the bottom surface varies at a co-astant rate, the side surfaces are thermally insulated, and the apper surface has a heat delivery into a constant-temperature medium; this solution contains a series of functions wh: ..ch depend upon the roots g7of the transcendental, " equation tan ~il = - ji/h, where 1. is the thickness of the strip and h is the relative heat-exchange coefficient.

Even though the temperature field is tran- sient, the authors disregard the forces of inertia and discuss the problem as quasi-static. The stresses obtained (as well as the temperature) are in direct ratio to the heating rate. With ideal thermal insulation ( h = 0) the stresses at a certain moment become practically constant. The stresses reach their greatest magnitude on the heated surface. V. K.

When heating the samples intensively the breaking occurs in consequence of the temperature stresses. The authors investigated cylindrical samples under the influence of torsion and t~mperaturqincrease.

Investigations on the temperature distribution gave the result that modifications of the medium surrounding the machine part or of the temperature of this medium cannot save the production part from temperature stresses. The fatigue strength of cylindrical samples depends among other things on its diameter; in investigations on torsion e.g.it was ascertained that the increase of the diameter from 10 to 200 mm 0aused a decrease of fatigue strength down to 40 - 509/o.

In the present paper, the effect of internal friction on the fatigue strength is investigated. Internal friction in a specimen undergoing test leads to the evolution of heat which in turn leads to the development of thermal stresses.

Diffusion in a non-uniformly heated strained layer in the presence of mass-exchange with the ambient medium PERIODICALt Ukrayinslkyy fizychnyy zhurnal, v. 7, no. 6, 1962, 652-659 TEXT: The relation between the processes of diffusion, heat con- duction and deformation in a binary isotropic solid solution is considered for the case of an infinite layer of'thickness 2 1. The differential equations and the boundary conditions for these pro- cesses are set up; thereby certain simplifying assumptions are made. The infinite layer is subjected to stretching and bending; is heated by convection with the ambient medium; an exchange of At atoms may take place between layer.and medium. The system of equa- tions reduces to two: Card 1/4 S/185/62/007/006/009/014 Diffusion in a ...

The stress-strain re- t lations are set up. In order to determine the stressed-strained state of the layer, it is necessarY_--,,,to find the 'distribution c(x,--7) of the solute and the tempbra~ure distribution t(x,?,I. These are obtained by solving system (5)'-and the corresponding boundary conditions. The formula for c(x,--L), thereby obtained, is consider- ably simplified by assuming that the settling time of the thermal regime is considerably smaller than that of the diffusion process.

D407/D301 The simplified formula shows that the change in the concentration of the solute is a result of 3 different diffusion proces~�es: The first oroce~ss is due to the difference in chemical potentia1sy the second,to the strain gradient (due to the.force P and moment and to the strain due to the temperature variation, the third L. -ion of the so- is thermodiffusion. In the case of vacuum evaporat, lute the obtained formulas are modified (by setting the chemical potentials~equal to zero). In a stationary process, the stresses in the layer arise as a result of the external forces only. The strain comp!onents consist of three terms; the first is related to the force P and the moment M, and the other two to the diffusion .processes a'nd the non-uniform heating. From the 'strain tensor, corresponding to the state following the removal of the applied load, it is~possible to calculate the radius of curvature of the middle surface of the layer; two formulas are obtained for the ra- dius of curvature, corresponding to the residual strain. These formulas can be used in the*experimental determination of the phy- sico-mechanical constants of materials. t Card 3/4 Diffusion in a ... 3/185/62/007/00-0/009/014 D407/D301 ASSOCIATION:- Instytut mashynoznavstva ta avtomatyky Ali UkrRSR, .

The authors determine the temperature field in a hollow body (in- finite cylinder, sphere) whose surfaces exchange heat with a surrounding medium of constant temperature in accordance with Newton's law. The-temperature of a ...-.medium'filling up'the body varies by a periodic law. Using the equation.of heat and corresponding boundary and initial conditions the general solu- tion of this equation is sought for in the following form: V .Card 1/3 S16761621009100010091010 Forced thermo-elastic oscillations in...

After a certain time interval,"asymptotic thermal"conditions set in and the temperature at any point oscillates with the same period as that of the inner medium, but with a different amplitude and phase shift. Rigorous solutions are found for the case of a hollow cylinder in terms of Tompson functions, and for the case of a hollow sphere in terms of hyperbolic functions. As an example, a practically important' case OIL- pipelines in thermal electric power stations is consideredi when the outer surface of the cylinder (pipeline) is thermally insulated. The second problem dealt with is the determination of the stressed-strained-state of the bodies subjected to forced thermo-elastic oscillations-caused by periodic changes of temperature according to the same law (5). To calculate stresses, formulae derived by L. I. Lurtye ("Prostranstvennyye zadachi teorii uprugosti", Spatial probl Iems of the theory of elasticity, GITTL, 1955) are used. The expressions for radial and tangential stresses are inserted into the equation of equilib- rium, and the differential equation obtained for displacements Uo(pt) is solved.

For the latter case, conditions of axial strain are of importance. Two cases, when the cylin- der ends are fixed and free, are considered and corresponding formulae for axial stresses are presented. The formulae are considerably'simplified when inertia forces can be neglected. Comparing the results with thetknown Timoshenko's formulae for a quasi-stationary problem, the authors conclude that the formulae dprived in the present article represent a geneialization of Timoshenko's f6rmulae extended to the case of steady-state conditions of forced oscillations.

(Llviv) On singular solutions of the dynamic problem of thermo- elasticity for an infinite medium PERIODICAL; Prykladna mekhanika, v. 8, no. 3, 1962, 303 - 310 TEXT: The thermoela,9tic state of an infinite medium is considered, subjected to concentrated periodic forces. The author proceeds from the system of differential equations of thermoelasticity which make allowance for the influence of the strained state on body tempera- ture. The forcesp concentrated at one point, are considered as body forces in the limit which act within an infinitely small neighbor- hood of the point. 'This makes it possible (by using the 6-function apparatus) to reduce the problem under consideration to solving the system of thermoelastic,equations in the presence of the specified forces. The original system of equations is a2u Au + (fV -I) grad div U-c2 cL(3fP - 4) graw' Card 1/3 S/198/62/008/003/006/008 On singular solutions of the D407/D301 8t div U' = 0 (1.2) where is the displacement vector; t - the temperature; the bo- dy-force density vector; a - the temperature coefficient of linear lexpansion;-~,t - the thermal conductivity; P - the ratio of the velo- city V 1 of the longitudinal wave to the velocity v V The function -ft is expanded in series near the origin o.L coordinates.

Energetika, no. 9, 1966, 43-78 TOPIC TAGS: atomization, fuel atomizer, fuel injection, spray nozzle, 9/)l /_~OWJ DR6PI~:r -ABSTRACT: the atomization of liquids by means of a gas stream is used in various technical devices such..as nozzles, coolers, reactors, absorbers, etc. Two formulas have been previously derived for the approximate determination of the hydraulic losses' in thr-be devices. However, these two formulas account for only the loss due to the energy expended in accelerating the droplet's to a given velocity, while'the entire pressure loss actually consists of energy used,for the deformation of the liquid jet, droplet formation, acceleration of the droplets, the friction of the gas on the I- surface-of the liquid, and displacement of the liquid film. Therefore, in the presents study, experiments were made to take into account these other factors. An assenbly was*used in which an air stream entering through a diffusor atoniomizes the liquid (water) which is injected through radial orifices (0.3-3 mm in diameter) into the Card 112 UDC: 532.501.312+533.27 PODSUSHNYY, A.M., kand.tekhn.nauk, dots.; MAROCHEK, V.I.., red6 (Economic indexes of steam power systemo],K Yoprosu o pokazateliakb ekonomicbnosti parosilovykh uBtanovok. iladivostok, 1959. 16 P.
