关于fluent多孔介质非热平衡问题

非热平衡模型，提示要新建一个solid区域，请问后面那两个系数是根据什么定义的

看了帮助文件后，有这么一段英文：The non-equilibrium thermal model available for porous media in ANSYS FLUENT is based on a dual cell approach. This approach is referred to as “dual cell” because it involves a second solid cell zone that overlaps (i.e., is spatially coincident with) the porous fluid zone; the two zones are solved simultaneously and are coupled only through heat transfer. ANSYS FLUENT can automatically create a solid zone for you that is a duplicate of the porous fluid zone. Alternatively, you could create a duplicate cell zone manually using the mesh/modify-zones/copy-move-cell-zone text command, or make sure that the mesh you read contains two cell zones in the region where the porous medium will be defined. Note that you should ensure that the duplicate zone is defined as a solid zone, and that the two zones have similar levels of mesh refinement (as one-to-one mapping will be employed between the cell centroids of the fluid zone and the solid zone).

非热平衡模型是基于双重区域耦合的，貌似只有heat exchanger模型里有dual cell设置，但那里面只能设置成流体与流体的耦合，有懂的大神么
