Question about Tutorial 13 of CFX

Hamilton · May 13, 2012, 05:54

Dear friends,
In fact in the tutorial 13 of CFX the flow between an annular is solved, which the inner circle rotating around its own axis, as a project I want to simulate that annular when the inner circle rotates around the axis of outer circle which is fixed, does anybody know how can I do that ? I think I should use mesh motion but I do not know if I should define the velocity of inner circle or location of inner circle ?

Please help me.

Sincerely

This is easily done using rotating frames of reference. Have a look at the tutorial examples 14, 26 and 33-35 for tips on using RFR.
