Hey guys,

I'm trying to include a thermal analysis into my problem.

I'm modelling the thermal comfort in my solar car. I have the interior airflow already and I want to turn on the energy equation and add some heat into the car cabin. I will be setting the inlet temperature (natural air) at 293.15K (20 degrees celcius). The problem I am having is to know which Wall thermal boundary to set. I am thinking between heat flux and temperature. The main heat will be coming from the solar radiation actually...but I just want to keep it simple and assume that the inside temperature of the cabin reaches up to 323.15K (50 degrees celcius, travels through the desert). The car is made from Carbon Fibre (I will need to assume a heat flux for this).

So If i choose the heat flux option, i get heat flux W/m2 and Heat Generation Rate. I am confused what is the heat generation rate w/m3. Actually, does anyone mind explaining what the heat flux option does? So at the wall boundary, the first cell, heat (at the heat flux and generation rate) is generated into the car interior?

If i choose the temperature option, I get a "Temperature" and heat generation rate. How would this be utilized?

Also for Material Name: It is currently set to aluminium, with it's properties. I'm assuming Ill have to change this aswell.

Cheers Guys, this is quite urgent. My thesis is due in less than 2 weeks. Appreciate the help! Sorry for the broken english, panicking here!

Thanks!
