Hello my friends hope you be well.
I'm simulating a wind turbine using body force by BEM method, which I apply to my fluid domain by UDF in fluent.
I can see vortex and wake after my turbine when I use LES model, but the problem is I can't see any vortex when I use K-w SST model. although I can see opposite normal velocity to plane which cross my turbine corresponding to my rotational axis ,which I attached here.
The picture shows the y-velocity in zx plane.
