I`m running calculations on a propeller. I have one domain which is in rotating motion. It is 120 degree, since the propeller has three blades. I turned on the alternate rotating model and calculated it but the streamlines in the outer regions show radial movement altough they should not be influenced by the prop. Furthermore I have Imbalance of 1e-2 for v- and w-mom on a constant level mainly for the periodic boundary. I guess there is a relation between the numerical mistake and the streamline plot. I also tried a to place a counterrotating wall instead of a free slip for the outer boundary with no succsess.
Please help. Thanks.
