Calculate pressure drop coefficients in x,y,z, direction
 

Hi to every one,

I'm actually modelling a filter in 3D. The mainly parts are cylindrical filterelements with a defined thickness and length. I'm using the porous meda modell to eveluate my first solution where i used the porous jump modell.

Now my question, can anybody tell me how to define the pressure drop coefficients in the 3 direction because I think they could't have the same values or isn't it??

thanks for replies
