[Z.N.A]

Hello,

I'm trying to perform a cooling plate analysis for a battery. The cooler channel has common surfaces with the aluminum plate(fluid solid interface). Therefore, I defined the interface surfaces in mesh and matched them in the interface section in fluent. I want to change the material of the cooling channel but leave the plate as aluminum. I tried to make a new definition using copper in Fluent database, but there was no change in the results. I think it should appear in cell-zone for me to change the material, but I don't know how to do it because the channel whose material I want to change is also fluid domain. Could you help me, please?

Could you post a picture of what the domain looks like? Specifically how the materials are stacked on top of each other and which material you would like to change.

If I understand correctly: you have a solid aluminum domain, some interface material, and then a fluid domain. If you want to change the material in between the aluminum and fluid you will have to define the interface as a coupled wall. Under options for the wall, you can select the new material, copper, and give it a wall thickness. In the heat conduction calculation it will add the layer of copper into the calculation of heat transfer from the fluid to the aluminum.

Let me know if I understand your setup correctly and I can provide some more detail on how to achieve this.
