摘要

Bifurcation and oscillation were studied for the natural convection in a horizontal layer of low Prandtl number fluid using SIMPLE algorithm with a kind of QUICK scheme. It can be found that the numerical results are related to the initial conditions adopted for the calculation and the flow fields have the same flow patterns as the initial when Rα_d < Rα < Rα_u. When Rα > Rα_{cr ,} the fluid flow and heat transfer become unsteady. Rα_cr is related to the flow pattern of initial flow field.
