modeling natural convection in tilted channel
 

Hello there,

I am modeling natural convection case for a tilted channel Using Fluent 6.3. My fluid is air and the temperature diference between the plates range between 10 to 30 celsius. I am using ideal gas law and I have specified the gravity. What Should I use for inlet boundary condition? If it is an pressure inlet, what should be my value? Any advice will be greatly appreciated, thanks
