NUMERICAL MODELING OF CONJUGATE HEAT EXCHANGE DURING COOLING A HIGH-TEMPERATURE METALLIC BODY BY A GAS FLUID MEDIUM FLOW
S.S. MAKAROV, M.Y. AL’ES, N.A. BALOBANOV

The results of numerical modeling of heat transfer during the cooling of a metal cylinder body by a stream of gas fluid medium in a vertical annular channel are presented. The results are obtained on the basis of the mathematical model of the conjugate heat transfer of the flow of a gas fluid medium and a metal cylinder in a two-dimensional nonstationary formulation, taking into account the axisymmetry of the fl ow of the cooling medium with respect to the longitudinal axis of the cylinder. To solve the system of differential equations, the control volume method is used. The flow field parameters are calculated by the SIMPLE algorithm. For the iterative solution of systems of linear algebraic equations, the Gauss-Seidel method with lower relaxation was used. The results of calculating the heat transfer parameters for cooling by a stream of a gas fluid medium of a high-temperature metal cylinder are taken into account, taking into account the evaporation. The values of the temperature of a metal cylinder are determined when cooled by a laminar flow of the medium. The intensity of the change in the cooling rate of the cylinder is analyzed depending on the proportion of gas in the liquid and the time of the cooling process.
Key words: mathematical model, the conjugate heat transfer, metal body, fluid flow, numerical calculation.
