NUMERICAL FLOW VISUALIZATION AND THERMAL TRANSPORT PHENOMENON OF BENARD CONVECTION IN A THIN LIQUID LAYER INDUCED BY EVAPORATION
RÉSUMÉ
A numerical study is performed on heat transfer and fluid flow in natural convection in a very thin liquid layer induced by surface evaporation, irrespective of its being cooled below or adiabatic. The two-dimensional governing equations are discretized by means of a finite-difference technique and solved numerically. This study shows that (1) the flow structure and temperature distribution in the liquid layer are predicted; (2) the liquid layer consists of two strata: heat convection taking place in the upper stream and heat conduction taking place in the lower one; and (3) the wave motion appears in the upper liquid layer, and the fluid flow is stationary in the lower one.
