The Effect of the Positive and the Negative Initial Values on Benard Fluid

Abstract:

Benard convection model is a famous model in non-equilibrium thermodynamics. It had been widely studied, but we had found there are few of the studies on the effect of different initial values on Benard fluid. Benard convection model of free surface are established for simulating two dimension stable flow field with different Benard cells. When the Ra Number is varied between 10050 and 78725, the positive and the negative benard flow with 2 or 3 Benard cells are used as the initial value in the numerical simulation corresponding to the same conditions. Results confirm that the different initial values have no effect on the formation of stable Benard cells. This study is a successful application of numerical simulation in the issue of Benard.
