Hello everyone, I am trying to model the heat transfer from the body and windows of a car moving on a road in regular conditions. For the walls boundary condition in thermal, I chose mixed  as I am accounting for radiation from sun and also convection w.r.t air. If the outside temperature is 305 K,

1) Is the free stream temperature 305 K?

2) What will be the external radiation temperature? 

Thank you

Hello,

Is your mesh inside or outside the car? If it is inside the car and you are modeling the HVAC system, please use the outside temperature as your free stream temperature. Yes, 305 K seems to be a good temperature in this case. The same goes for the external radiation temperature. This is basically your T_infinity.

Thank you.

Best,

Karthik
