Hello everyone,
I want to simulate the airflow through a car radiator (which will be modeled as a porous media) and the heat transfer between the corresponding fluid-solid-fluid regions. I am working with the heatExchanger Case under chtMultiRegionFoam, but in this case, the fluid regions are coupled by fvOptions "constantheattransfer". So this case is not solving the multi-physics problem behind, but rather constantly cooling down the porous region.

My question is; Is there a way to solve this Thermo-Hydraulic coupling problem in OpenFoam? How can I make OF solve the momentum and energy equations simultaneously? I've never seen a similar problem modeled in OF Does anyone have an idea?
