air conditioning in cars

Tadiwos

Hello CFX Friends,

I want to model air conditioning inside a small BMW car. I have two questions:

1) How much detail should I make the geometry using CFX Build? It is difficult for me to represent everything inside the car i.e, the seats, wheel drive, brakes.....

2) Is it two dimensional or three dimensional flow should I use?, I would like to get good validation results interms of temperature.

3) Is there any one who is working on such kind of research. if there is please post your address and I will try to contact you.

Thank you very much for your help.
