Hi guys,
I'm simulating turbulent free convection over spheres with constant wall temperature, i'm using the steady solution and working in 2d, the thing its that when i'm use the laminar solution, the heat flux result its a half of what suppose to be and when i use the turbulence models the heat transfers goes up, even using the LRN models, what can i do to obtain better solutions?
