Hi all,
I want to simulate a porous material which is "anisotropic". For that I have to input meaningful porosity settings.
Since it is an anistropic case, I have to choose the "Directional Loss". In this way I have to input :
1- Directional Loss : X-component , Y-component, Z-component
2- Permeability and Resistance Loss coeff. both in streamwise and transverse.
I have two questions regarding these mentioned points :
1- What are exactly these X, Y, and Z components in the Directional Loss part and how are they calculated? (I could not find it in CFX Help)
2- I have an anistropic porous domain. So I have to have three different Permeability and Resistance Loss coefficients in each axis-->(x,y,z), but in the settings we can only specify Streamwise and Transverse Loss. So why is it like that ?
I am looking forward to your help please
refer the following link. Its a tutorial for specifying inputs for the porous media in FLUENT.
