Porous Media Inertial and Resistance
 

hi, What is the difference between inertial coefficient and resistance coefficient il inputs for Porous Media ? Thanks

Re: Porous Media Inertial and Resistance
 

one is inertial resistance and other is viscous component of resistance

read Ergun equation for pressure drop per unit length to understand more

I want to model a micro filter, This filter (membrane) is rectangular (10×5 cm) with the thickness 12e-5. so,I calculate this parameters from Ergun equation which D=1e-6, because of the Micro filter type. is this assumption true??
i think this is very thin filter so there in not flow through in the membrane, in this situation is inertial coefficieant higher in Y direction? or not?when i set y-direction inertial coefficient higher than x-direction got better answer! is this resonable?

I am looking forward to hearing from you.
Sincerely yours
