I'm pretty confident in the mesh setup, it's a Structured C-Type mesh. I've reduced the cell size to ensure large eddies are capable of being captured. (max y+ is approximately 1, courant number is around 0.5).
Apologies for the poor photo (I'm away from my desk at the minute), but here's a velocity contour plot illustrating the vortex shedding and eddie formation towards the rear of the TE:
