Hi,
(I am a first time poster. If in your experience this question suits more to other forums please suggest me that)
I would to like to ask my question in series of increasingly complex scenarios.
1. A hollow cylinder (diameter/length = 1.585 and diameter = 0.5 m) with holes in its rear surface is rotating. Rotation is alternatively clockwise/anticlockwise at 50 RPM for most time of test and at 1400 RPM for short time in middle of run-time. Schematics for setup and RPM profile are as follows:-
Are there any correlations which will give me how such flow is related to pressure drop across cylinder as whole w.r.t. dimensionless parameters like Re and Taylor number. Any other literature reference is also appreciated.
2. Now if there is outer stationary cylinder around the rotating one, how would flow be divided and what would be resultant pressure drop. (I am interested in overall pressure-drop in flow through component). Again any reference to specific study is appreciated here. System is represented below:
3. Lastly (this may be asking a bit too much), what would happen if inner roatating cylinder has some labile solid sheet like substance which covers 60-70% volume of inner cylinder? I am assuming that more flow would go through annulus. Could a relation between obstructing substance's amount and partition of flow between two possible regions be formulated?
(please inform me if such detailed questions are not preferred/expected in this forum.)
Thank you,
