realizableKEpsilon is very sensitive to inlet condition
2 Attachment(s)
After many test cases launched on different geometries, I found realizableKEpsilon is very sensitive to the inlet turbulence condition. You can run the pitzDaily test case by adjusting only the k inlet value. In the following 4 tests, I set them as:
kEpsilon: kInlet = 0.375 kEpsilon: kInlet = 0.0375 realizableKEpsilon: kInlet = 0.375 realizableKEpsilon: kInlet = 0.0375 You can see the first three predict almost same nut. But the last one does not. |
I have no idea why I cannot upload more pictures (404 forbidden), I will come back to update again.
