Convection Heat Loss from a Solar Cavity

Please login with a confirmed email address before reporting spam

Hi all,
I working for the convective heat loss form a heating chamber wich has an isothermal temprature of 1000Kelvin.I have used non isothermal flow module in comsol and used air as a fluid transporting heat from the chamber to the atmoshper considering natural convection.I have considered weekly compressible navier stokes with heat trasfer module.But my doesnt work.
what I found that I have high operating tempraure and COMSOL non isothermal module is uable to solve that.I have tried each and evry option.
Please do guide me how can I solve my model on COMSOL3.5a.

Your early response will be highly appreciated and thanking you in Anticipation.

Regards
