periodic boundary condition in taylorcoutte flow
Greetings to everybody. I work on 2D cfd simulation of taylor coutte flow using Fluent vs6. In my problem, the outer cylinder is staionary and inner is rotating.Can anybody help me how to give rotational velocity to the inner cylinder while defining boundary condition in fluent. I define inner cylinder as periodic but could not give a specific value to the rotational velocity.
Thanks for your kind help. Jaysree

Try to defined the problem as 2D axisymmetric instead of periodic.

Thankyou very much for ur help. But whenever I am using 2Daxisymmetric model it is the following error divergence detected in AMG solver: xmomentum
What to do further? Any idea please.

Change BC if possible... play with ur initial conditions...and solver...if using turbulence, then try to change the default values to min then increase gradualy to max to get convergence...

Hi,
u can try for a 3d case more easily than struggling for a 2d case for this simple geometry
