Hi,

I'm relatively new to CFD and I think I have bitten off more than I chew.

I'm trying to simulate the flow in a vertical smoker:



I have two velocity inlets (I have also tried these as pressure inlets too - gauge 0), a pressure outlet (gauge 0) and two symmetry constraints.

The fuel is set up as a heat flux (169635 w/m2) and the walls have mixed thermal properties.

I'm using the realizable k-e model with enhanced wall treatment, bouyancy effects are on (gravity too), radiation is DO. Air as an incompressible ideal gas.

My results aren't very realistic, they show the fuel to be at 300C+ but the air next to it at 10C...

Please help.
