Abstract
The process of buoyancy-induced, developing, turbulent flow in a vertical parallel-plate channel is studied numerically to simulate the performance of an innovative reactor-vessel air cooling system under abnormal operating conditions. The channel is subjected to different stratifications of ambient air temperature. The physical model takes account of possible parameters-the ambient temperature variation, pressure losses at the inlet and the outlet, wall-to-wall radiative heat transfer, property variation with temperature-which influence the heat transfer in the channel. A κ-ε turbulence model is utilized in the numerical simulation. An implicit finite difference scheme is employed to solve the governing equations and variable grid sizes are adopted in the computational procedure to facilitate the task of solution.
