Centrifugal pump simulation using fluent -- CFD Online Discussion Forums

April 25, 2023, 11:00	Centrifugal pump simulation using fluent	#1
Ahmed Abotayel New Member Ahmed Join Date: Apr 2023 Posts: 8 Rep Power: 3	Hello everyone, I am working on centrifugal pump simulation case via ansys software, I have set the boundary conditions of the case then by mistake I put the rotational speed 1500 rad/s instead of 1500 rpm the contours of pressure and velocity in these iteration were normal when I changed the rotational speed to 1500 rpm with the same settings and boundary conditions the contours were not normal and the residuals were not stable. Can someone help me to find out why the simulation goes wrong in the case of 1500 rpm?
