do someone know why the porous model is not available in eulerian multiphase model? there is no possibility either to use porous baffle. So how can we model porosity?

Porous media may not work using EMP since with EMP each phase gets its own set of transport equations; you would have to have a separate porous medium for each phase somehow to get it to work.

I would imagine if you wanted to do this you'd have to make your own source term.

me3840 is correct

porosity in ccm+ is done via momentum sources for the physics that it does work for so the same technique can be used for each emp phase using your own momentum source equations

it would look something like this

delta-pressure / delta-length = - (interial-porous-coef * abs (v) + visous-porous-coef) * v
