hot air-wind turbine
 

hi
i'm new to fluent. my master project is to simulate a combined hot air and wind turbine ventilator (somehow like solar updraft tower power plant) the sun ray is absorbed by black plate covered by transparent layer makes the air to flow and it's conducted to rotate a ventilator(made of some flat plate around a circle). I want to know if it's possible to do two physical phenomena (heat transfer and aerodynamics) with gambit 2.4 and fluent 6.3? if yes do I have to define a regular turbo volume in gambit for moving part?( ventilator) what kind of solver should i choose?
thanks
