hi everybody
Recently,I have simulationed square duct flow with new turbulence model,but there are some problem. the BC in x direction is cyclic, in yz direction is wall,it’s very simple.And there is a fixed mean flow velocity in x direction,using pressureGradientExplicitSource in fvoption ,the pressure gradient is calculated automatically first,the result is reasonable when i run the case with RANS model, Code:
pressure gradient = 0.179097 Code:
pressure gradient = 0.0903267 benqing |
