Hello people,

I have a simple model where porous domain is inbetween two fluid domains. Hot fluid is given as Input. I am using Specific heat capacities for fluid and solid material in porous domain to be temperature dependent. Also the density of fluid is temperature dependent. Energy calculation formula used 'Integral over (mass_flow*C_p*DeltaT )dt. Is there a way to calculate C_p for each cell?(in ansys cfx pre or post).

The opearating temperature range is about 800°C, so I do not want to take single average C_p value as it varies quite significantly between the temp range and compromises the Energy calculation.

In function Calculator I tried Function:volumeInt , Location: porous, Variable:Specific Heat Capacity at Constant Pressure. What volumeInt(SHC)@Domain returns actually?

Ultimately I need to calculate Energy in porous region/solid, where it is calculated using C_p that is temperature dependent. Any suggestion?
