I am conducting a simulation of a spinning golf ball traveling through the air. The simulation method involves using a moving reference frame. Two fluid domains are created: an outer rectangular domain and a rotating spherical domain containing the golf ball.When examining the contours and vectors, it appears that the golf ball is only experiencing rotational motion and not the tangential motion from the inlet flow. The wake region behind the golf ball is pointing vertically downward, which is incorrect. <\/p>\n

I am using a steady-state, standard k-epsilon model. The inlet speed is set to 45 m\/s, and the rotational speed of the domain containing the golf ball is set to 4000 rpm. The walls of the golf ball are set to a moving wall condition with 0 rpm relative to the adjacent rotating domain. I am trying to make the flow similar to the first picture ( which is how it suppose to be). Could you please help me resolve this issue?<\/p>\n
