Thermal effects on Rayleigh-Marangoni-Benard instability in a system of superposed fluid and porous layers

摘要

Thermal effects of the heat transfer at free surface (represented by Biot number) on the Rayleigh-Marangoni-Bfinard instability in a system of liquid-porous layers with top free surface are investigated numerically. The results indicate that this thermal effect can evidently lead to the mode transition of convection, which is overlooked in previous works.
