I am wondering which approach I should take to solving the problem I am having. I want to investigate cooling battery modules in an electric vehicle, where the modules are in an enclosure, similar to as shown in the image below.
I am modelling the entire drivetrain of the vehicle, so there will be a motor before and after the battery pack. I have since found out that, trying to use conjugate heat transfer, I cannot simply stick a motor before and after the battery pack with a fluid flow going through all components due to an issue with simulating internal/external flows at the same time. So, could I simulate the flow through each compartment separately (front motor, battery pack, then rear motor) and use pressure outlet conditions from the front motor compartment as the velocity inlet boundary conditions for the battery pack? That’s the only way I can think of to model this problem, so wondering if that’s valid
