that looks like a poor mesh, what is the mesh quality, see the orthogonal quality n post that, use inflation on all walls, just to cover your boundary layer not like the one you have ATM

this is not orthogonal quality, go to statistics it should be there, read some meshing tutorials by Ansys, google them
