Axial Flow between rotating cylinders

pavitran · February 28, 2015, 07:01

I have a query regarding axial flow (turbulent) between rotating cylinders (Same angular speed). Please see the attached image. The radius of the inner cylinder is 200 mm (please see the attached image) and the outer cylinder radius is 300mm and the flow is parallel to the axis of rotation. My queries are:

1. Should I consider the computational domain as stationary and inner & outer cylinder as rotating wall?
2. Or should I consider the entire computational domain as rotating domain?

You should use a stationary domain and the walls as a rotational tangential velocity.
