Fluent Stirling Porous Medium
 

Dear All,

I would like to simulate Stirling engine regenerator in Fluent, my case as follows;

2D
Axisymmetric
Porous Medium (which is moving)

I have a sinusoidal pressure inlet, however I am encountering huge amount of reversed flow, I do not know how to deal with it, another thing pressure remains constant in porous medium as well that it is not physically true.

Is there anyone to work same cases?

Your quick assistance will be highly appreciated.
