Heat Flux in the Near-Wall Region
Does CFX have a 'switch' to activate the Heat Flux in the Near-Wall Region or do you have to code the equations described in the solver theory yourself?

Re: Heat Flux in the Near-Wall Region
Dear Malcom,
Are you referring to the turbulent wall function boundary condition closure for the energy equation? The equations are already in the code, and are active when you select a turbulence model. Why do you think that you should code the equations separately? Opaque. |
Re: Heat Flux in the Near-Wall Region
I'm referring to equation 187 of the CFX-Solver 10.0 Theory where qwall = ((rho x Cp x u*) / (T+)) x (Twall - Tfluid), i.e. the wall heat flux model that approximates a heat transfer coefficient.
Thanks |

Hi,
That equation is automatically used when you select a simulation with a thermal field and a wall boundary condition which will result in heat transfer (ie not adiabatic). Glenn Horrocks |
