SAE car radiator modelling - URGENT!!!
 

Hello all!

I have a model of the sidepod for the SAE car with the radiator plane inside. This structure is encased inside another volume acting as an imaginary wind tunnel.

This meant that I had to use the boundary conditions of vent inlet and outlet. I have values for the loss coefficient but I am confused as to what value to input into the total gauge pressure

Any tips would be greatly appreciated
