| 摘 要： | 建立了用于模拟二维Benard对流现象的格子BGK模型，该模型要求粒子碰撞过程不仅满足质量和动量守恒，而且满足能量守恒，结合二迭加FHP模型和三迭加HPP模型，确定了此模型的平衡态形式，导出了此模型对应的宏观质量、动量和能量方程，用该模型成功地模拟了二维Benard花纹．

| Abstract: | The lattice BGK models of simulating two dimension Benard convection are established. In the collision process, the particles satisfy the mass, momentum and energy conservation laws in the models. Based on the two--overlapped FHP model and three--overlapped HPP model, the equilibrium distribution functions are presented. The macroscopic mass, momentum and energy equations are derived from the models. The Benard pattern of thermal convection phenomenon is simulated successfully by using the models on SUN workstation computer. |
