Simulating a heat exchanger with different cores
 

Hey,

i am trying to simulate a heat exchanger (see the screenshot, the gyroid core is hidden) that has water flowing through it and a heat source at the bottom. My boundary conditions to the environment are adiabatic and heat exchange occurs only at the interfaces of (fluid to case) and (fluid to core).
The core is connected to the case.

I want to study the heat transfer with different cores. What values should I observe?
The fluid outlet temperature is the same for all simulations, only the distribution of the heat transfer quantity between the interfaces is different.
