我看到一个比较关键的地方:我觉得,墙函数是非常关键的边界条件。 特别是在 RANS 中。
我看到你对 alphat, epsilon 都用了墙函数,速度为什么不用,没有理由?
有确定边界层节点足够覆盖边界层了么?
我这有个参考资料:
ansys 17 手册:
The thickness of the prism
layer should be designed to ensure that around 15 or more nodes are actually covering the boundary
layer. This can be checked after a solution is obtained, by looking at the turbulent viscosity, which has
a maximum in the middle of the boundary layer – this maximum gives an indication of the thickness
of the boundary layer -
