Default enthalphy for solid of porous medium
Posts: n/a

According to some response, the solid phase temperature of porous medium for non thermal equilibrium case can be solved by additional variable of solid enthalpy.

Some said, the solid temperature = H/Cp (1) some said, the solid temperature = H/(mCp) (2)

checking on the unit of H (joule), the units in equation (2) tally. Equation (1) not tally.

However, when thinking to implement the boundary condition for solid in terms of enthalphy, Enthalpy has to be computed from (1) or (2), if (2) is correct, what is the mass at the boundary? The boundary has no mass involve.

CFX will countercheck all units input and will prompt error if units doesn't tally, and seem the input of (2) is correct in terms of unit. Could someone guide me through?
