fluent湍流模型里的Viscous Heating 和Full Buoyancy Effects是什么意思,有什么用?它们对应控制方程的哪部分?FLUENT是怎样求解方程的,真让人纠结啊[img][/img]

看下官方的解释:Viscous Heating (if enabled) includes the viscous dissipation terms in the energy equation. This option is recommended when you are solving a compressible flow. Note that this option is always turned on when one of the density-based solvers is used; you will not be able to turn it off.viscous heating 对于高粘度的液体应该选用,此时粘性剪切力会做功。粘性热只有在流体粘度较大时才考虑,由于粘性热的数值相对来说非常小(在传热问题中),通常都忽略不计
