I running one case in which I am interested to know how much air is getting suck by the propeller and up to which distance it suck in ducted. but I am getting zero results for pressure and moment.
My area of interest is how much air velocity is getting created in due to suction from propeller at a speed of 11000 rpm.
how much pressure drop is created due to suction of air by the propeller.
