Local Thermal Non-Equilibrium for Copper Porous Matrix Filled with Phase Change Material

Please login with a confirmed email address before reporting spam

Hello,

I am simulating a porous thermal energy storage that is made of Copper-porous matrix and it is filled with phase change material (PCM)

I want to simulate this system for a cubic domain that is closed by solid walls, no flow enters and exits the domain, and its subject to heat flux from one side and a constant temperature from other side. I want to have "local thermal non-equilibrium" between the PCM and the porous matrix but the multiphysics says non-applicable for the domain.

I've used a "heat transfer in liquids" for the (solid + liquid state) PCM. and a "heat transfer in solid" for the porous matrix. for the fluid mechanics i've used the "Free and porous media flow" physic.

In local thermal non-equilibrium when i try to couple the "heat transfer in solid" for the porous media domain with the "heat transfer in liquid" for the PCM, it says: non-applicable.

There is a comsol application named "Packed bed latent heat storage" that has local thermal non-equilibrium multiphysics, but my domain is not packed bed.

I'd really appreciate any help on how to couple these physics or any tips if i'm doing something wrong here.
