Natural convection
 

hello guys,

I'm modeling 2D natural convection in a chimney. I'm using pressure inlet and pressure outlet for my in flow and out flow respectively.

I'm suppose to key-in the perssure value, i put in the atmosphereic pressure. However i 'm not getting wat i wanted. Anyone can help me with this? thks.

Pressure inlets and outlets should work OK. Remember that these are pressures above the specified operating pressure. If you have a 1 atm operating pressure and a 1 atm inlet pressure, you have specified a 2 atm absolute pressure at the inlet.

Thanks Evan.
