Pressure field analysis for blade

Hi,
Maybe someone can tell me if this image has physical sense...
Blade rotation, direction and velocity of fluid in axis Z, Frame fluid stationary
Thanks

Hi
Generally it is expected that a pressure difference exists on sides of an airfoil. This can be observed in the pic attached. But this in not enough to judge on its physical meaning. What is the diecton of rotation? Is that a compressor or a turbine blade? Besides that it seems that on suction side there is a huge separation zone which is not reasonable and can be caused by impoper setting of boundary conditions.
