case example for HVAC problem

kevin

i am now trying to finish my final project about ventilation on ship engine room. i want to know heat tranfer from engine (heat source) and air flow in ship engine room. im confuse about fluid boundary and solid boundary on my problem. i wish to ask if someone have a case example or tutorial bout the room ventilation (including boundary solution)! or maybe where i can find the case example or tutorial for my problems.

thanks before
