September 23, 2016, 05:22	Rotating domain end point	#1
Bdew8556 Senior Member Brett Join Date: May 2013 Posts: 212 Rep Power: 13	Hi all, I'm currently running some frozen rotor simulations on centrifugal compressors using CFX. I'm curious as to when the rotating domain should end, ie how far downstream of the blades should the impeller-diffuser/rotating-stationary interface be? For example should it be 10% offset from blade radius, 20%? immediately after the blade tip? I'm using a vaneless diffuser just fyi All the best! Brett
