摘要：
A finite-volume scheme is used to simulate super-critical natural convection flow in a side-heated cavity with height/width aspect ratio of eight. The flow is unsteady with travelling waves circulating around the cavity in the flow direction. Results on a range of grids with QUICK and central difference advection discretizations show that a very fine grid is required to ensure a converged solution is obtained. A linear parallel stability analysis has been carried out and it is shown that the basic wave structure of the flow is well predicted. Copyright (C) 2002 John Wiley Sons, Ltd.
