propeller in non-uniform flow
 

Dear friends, i am trying to compute a marine propellers in non-uniform oncoming flow. The propeller is inside a cylindrical rotating mesh, with the inlet at a couple of diameters haead of the propeller itself. What should I impose at the inlet to have at the propeller plane the nominal wake measured in the towing tank? If I impose the nominal wake at inlet it will reach the propeller partially diffused. How can I face this problem? thanks
