摘要
建立了一个模拟双扩散自然对流系统的格子Boltzmann模型 ,用此模型对受温度和浓度梯度驱动的方腔流动进行了模拟 ,研究了浓度Rayleigh数对传热传质的影响 ,并与其它文献的结果进行了比较 .
A lattice Boltzmann model is proposed for the double diffusive natural convection system.The flow in a square cavity driven by a temperature gradient and a concentration gradient is then simulated using the present model.The influence of the concentration field on the flow patterns is investigated,and some quantitative comparisons with other studies are made.It is shown that the present LB model can predict the flow characteristics correctly.
