Heat Flux Doesn't Work
 
Hi all,

I can't tell what I'm doing wrong. I'm trying to model 2D turbulent flow through a pipe. The lower wall of the pipe is held at a constant temperature and the upper wall has a heat flux of 7.795 W/m^2. When I run the simulation it appears there is no heat transfer through the upper wall.

I should be dumping A LOT of heat into the fluid, but the result of the simulation shows almost a constant temperature along the upper wall.

Please Help,

-Ryan

This doesn't seem like it should be a very difficult problem. Can't anyone help?
