Forces on Radiator

Horsepower · August 4, 2018, 05:39

Hello,

for my Bachelor thesis I want to model a radiator from a fromula student race car in FLUENT. I've allready implemented the radiator as a porous region and defined the viscous resistance coefficient (1/alpha) and the intertial resistance coefficient (C_2).
The flow field is showing good results in terms of the pressure drop and the velocity through the radiator seems to be modeled correctly. My problem is, that the force on the radiator is still calculated as to be zero. What do I have to do that FLUENT can calculate the force witch is operating on the radiator?

In advance, many thanks for the support.

I am in a similar situation but with a different problem, I am working on my FSAE team Sidepod and I’m trying to put the radiator on the simulation, but the flow don’t go through the porous media, it’s like my contact region was a wall zone. How do you set your simulation? Did you got any problem like these?
