Hi to everyone! i'm trying to select a correct approach to simulate a rotating pipe with a specific swirl numbers, in my real configuration there is a pipe rotating and then the flow (air and water) is entrained as a jet impingment to a flat plate at 90°. Also my model need to be in 3D this is order to evaluate erosion with DPM (Fluent).

i have a doubt it will be right to perform a cfd analysis of the 3d rotaing pipe (steady analysis) and then use this outlet condition to inital conditions for a short pipe (flow whole developed) and the distance to flat plate (transient analysis)?

Or it will be better to perfom the whole system.

i hear and reply any question about my cfd model
a lot of thanks !
