After you increased the min angle to 24 the convergence improved hugely. before at 17 degree as you see even the first order was not converging..
Is it possible to increase the min angle further.. i...

its the same mesh. I run it in RANS initially. Later when it has converged, i switch to URANS. If you are concerned about the peaks occurring after 800 iterations, then dont be.. because its normal...
