Dear all,

I am trying to simulate VAWT with pimpleDyMFoam on fe32 with k-epsilon turbulence model. But k is not being convected and keeps trailing the airfoils instead (image attached). Has anyone faced this problem before? Please help

Thanks,
LR

I have had the same problem before and did not have any luck in solving it unfortunately...

For what it's worth, I did notice that, for some reason, the Spalart-Allmaras turbulence model for fe32 does convect turbulent eddy viscosity downstream properly. Various other two-equations models (including k-w-SST) did not work for me though. Hopefully you can find your answers here!
