Use of "externalWallHeatFluxTemperature"
Hello,
To impose a real boundary condition with convection and conduction (and radiation) on a wall, I use the externalWallHeatFluxTemperature boundary condition: type externalWallHeatFluxTemperature; kappaMethod fluidThermo; Ta uniform 300; h uniform 10; kappa none; QrName Qr; value uniform 300; The problem is I do not know how to use the real temperature for Ta. I would like to use the temperature of the gas at the wall so it is not uniform and not constant. I try T but unsurprisingly, it does not work. Does anyone know how to do that ? Thanks. |
