Abstract

The process of buoyancy-induced turbulent free convection flow in a vertical parallel-plate channel with asymmetric heating is studied numerically to simulate the performance of an innovative reactor-vessel air cooling system. A two-equation k-ε closure model is employed to describe the turbulent motion, taking account of the effect of surface radiation between the two bounding walls. The governing equations are solved by an implicit finite-difference method. Results indicate that over most of the heated length of the channel, the flow is developing with the velocity profile changing continuously in the axial direction.
