  • 摘要: 采用格子Boltzmann方法,对4个壁面均为低温、低浓度,内置高浓度发热圆的充满均匀多孔介质的方腔内双扩散自然对流现象进行了数值模拟研究.分析了Darcy(达西)数Da(10-4Da≤10-2)和浮升力比B(-5.0≤B≤5.0)对内部发热圆表面平均Nusselt(努赛尔)数Nuav和平均Sherwood(舍伍德)数Shav的影响.模拟结果表明:除B=-1.0时,NuavShavDa的增加而增大;当-5.0<B<5.0,在Da=10-4时,NuavShav几乎不受B变化的影响;在Da=10-3Da=10-2时,NuavShavB的增加先减小后增大,在B=-1.0时取得最小值
