air mixer in a furnace
 

Hi Currently I am trying to model the effect of propellers in a box type furnace. The idea is that a very simple propeller rotating inside a furnace (box type) will help to increase the uniformity of temperature as well as increase the heat transfer coefficient. I tried to model this problem using fluent with several different methods. But every time I get a different answer, could any one please assist me on this matter?... I do appreciate if you could lead me a few example/tutorial files about this problem.
