Hello every one,
I am doing simulation chemical vapor deposition (CVD) of rotating reactor, pic 1. explain it in simple words it is a flow impinging a rotating disk. I put rotation value in boundary condition for the disk,pic 2. I repeat the solution using frame motion, pic 3. I am confused between these two results, which one is the correct, and why in frame motion entire flow is rotating. Any recommendations and hints are valuable to me. thank you in advance.
