SST K-w results for ahmed body
 

Hello,
I've been using k-e and sst k-w to model the flow over the ahmed body for a slant angle of 25. While for the k-e the flow remains attached over the slant surface, when modeling with SST k-w, the flow detached at the top and behaves similarly to that of a 35 degree slant. Does anyone know how to explain this?
Thank you guys
