LOUKS Aleksander L., KRESTIN Evgeny A., MATVEEV Andrey G., VESNIN Vladimir I. 17-24 p.

Heat pipe is one of the promising type of heat exchangers. But some processes in heat pipes are still studied not enough. Particularly there isn’t any unified theory of bubbles inception in a wick. Problems of layer wave flow demand to be studied. The paper views operating modes of heat pipes – evaporation processes at low heat flow rate and bubble boiling at ultimate transfer power. Different limits of transfer power and its experimental values are analyzed. The research shows that grooves with perimeter in the form of circle – with Ω-capillary structure of a wick are the most effective.

The problem of modelling of soil mass temperature field during many years service of heat pump

SAPRYKINA Nadezhda Yu. 25-30 p.

KOTENKO Irina A. 116-125 p.

The article views the first time appeared on the Web German military plan of Kuibyshev (Samara) city of 1942. This plan is of interest for studying the historical and building development of the city in pre-war and wartime. The article provides information about the organization of military cartography and topography in Germany, about the kinds of special cards and military-geographic documents and their purpose. The military-geographical city plans were the special maps. The author examines the cartographic features of schematic military-geographical city plan: sources for plan; executive stamp; scale; economic and geographical description (general legend) and the legend of points of interest; list of undetected important urban objects and symbols. The author concludes that the military plan cartography of 1942 is more accurate for prewar city. However, information about important military and industrial sites are detailed and relevant to the war. The study and comparison of the German and Soviet city plans and maps contribute to better knowledge of urban development of period under review.

Vibration protection of powerful inductors

YEGHIAZARYAN Alexandra S., ZIMIN Lev S. 135-139 p.

Electrodynamic and vibroacoustic problems during induction heating of solids with variable curvature of surface – primarily heating of slabs for rolling – are viewed. It is recommended to perform electrodynamic calculation on numerical model developed through coupled circuits method and virtual displacement law. For numerical solution of vibration problem it is worth to use finite-element method. In the general case for calculating of distributed forces Biot-Savart-Laplace’s law is used. This law permits to definite surface current density in a slab. Through inductor vibration model studies the form of inductor optimal shell is synthesized according to the criterion of minimal noise emissions.

Numerical study of natural convection in enclosed volume

KORTYAEVA Darya O., NIKITIN Maxim N. 146-150 p.

A numerical study of natural convection was conducted with Code Saturne soft ware package. A numerical model based on combined k-ω SST turbulence model was developed. The results of simulation of natural convection in enclosed volume of air were obtained in two variants of boundary conditions specification: by heat flux and by heat transfer coefficient. The problem was solved in a non-stationary formulation using a pressure-velocity coupling algorithm PISO. This simulation model adequacy is evaluated. Experimental data on the temperature profile in the central section is used as a benchmark criteria. Assumptions about the destructive factors reducing the accuracy of the solution, are partly supported by the results of comparative analysis of the intensity of convective mixing. Assumptions partially confirmed by the results of comparative analysis of the intensity of convective mixing, performed on the basis of upward velocity profiles for the heated air.
