Hi Federico,

Thank you very much again for your quick reply,

When I choose ∆X = 1.99E-04m (X+ = 120), my ∆t is 5.183641E-07. So i will perform simulation and see if I can get CFL <= 1 around my blade profile.

No, it is a single compressor blade (0.7 Mach) with periodic boundary conditions and i am trying to validate isentropic mach number vs chord against the experimental data (attached pictures).
