Fluent/filter/porous jump/pipe
 
Hi everyone
I'm trying to simulate a flow through a strainer (filter) in a pipe with a well-rounded expansion before, and an 90 degrees elbow after it, in 3D, using Fluent. To simplify, just considerate a pipe with a 'filter' inside : To do that I've modeled the filter as porous jump.
__________________________________________________ _______________

My boundary conditions are : Velocity_inlet - Outflow - Wall - and Porous jump

From the experimental data I get the permeability and the pressure jump coefficient for the porous jump condition.
I run it with a k-omega turbulence model.

But the results are not correct, it seems that it doesn't use the porous jump, and something weird, the pressure is higher after the filter, but it should be the contrary..

Any help would be appreciated :)

Thanks
Regards

Kevin
