rahul62 is on a distinguished road
I am trying to solve melting solidification problem in porous media. I have considered thermal equilibrium between porous media and fluid (solid and liquid). I tried the buoyantBoussinesqPimpleFoam solver, but I have to consider variable density also. So, I am trying buoyantPimpleFoam. I have added source term in momentum equations but this solver solves for enthalpy instead of temperature so I dont know how to mention effective specific heat(combined for porous media and fluid-I am using combined equation for liquid, solid and porous media) in energy equations and only change density of liquid part.
Can someone help me please.
