Urgent: How to model a stationary sphere in a pressure driven flow using Ansys CFX?
 
Hi,
My question is that how can I simulate to find the drag force on a stationary sphere in a cylinderical pressure driven poiseuille flow Using Ansys CFX 11.0.

What I am doing is

I made sphere in a pipe
Inlet condition is parabolic using Umax*(abs(1-(r/Rmax)^2)
Outlet condition is zero average static pressure
No slip at the cylinder and the sphere with zero wall velocity on both.

When I model it I do not get the right answer as availble in literature.

Kindly help me out and tell me where I am wrong.

Hey,

Wrong forum, if you expect help with CFX.
Here in the OpenFOAM forum, we only can advise you, to switch the solver. ;-)
