Modeling Heat Flux using FLUENT
Join Date: May 2009

I am trying to model a solar collector (using air as fluid) in FLUENT. Right now I am giving a constant temperature to the collector plate and using that to get the air flow pattern.
I want to make it a bit more realistic and use heat flux in place of the constant temperature. The energy at the earth's surface from the sun is available in solar data. So, I am giving it a heat flux of around 700 w/m2.
But the temperature reached in this case is around 400 - 500 kelvin which is unrealistic.
Currently I am using boussinesq approximation and laminar flow.
What else do I need to include in this ?
Could anybody please help me with this.

We would need more information to solve the problem. Can you send the model and give the reference for the heat flux of 700 W/m^2?
