Hi,
I would like to solve heat transfer from an air flow through a metal wall to surrounding air without modelling the solid wall thickenss (separate mesh). The BC would be set as: Internal wall temperature is calculated Internal heat transfer coefficient is calculated Wall thickens and conductivity are assigned External surrounding temperature is assigned Is it possible to use for this problem BC externalWallHeatFlux or is there some other BC for this propose? Is there some tutorial solving this problem? Thanks |

Hello Altan,
The externalWallHeatFlux fits perfectly to your description. Code:
wall { type externalWallHeatFluxTemperature; kappa fluidThermo; // fluidThermo, solidThermo //q uniform 1000; // heat flux / [W/m2] Ta uniform 300.0; // ambient temperature /[K] h uniform 10.0; // heat transfer coeff /[W/K/m2] thicknessLayers (0.1); // thickness of layer [m] kappaLayers (0.05); // thermal conductivity of // layer [W/m/K] value uniform 300.0; // initial temperature / [K] kappaName none; } Only supply \c h and \c Ta, or \c q in the dictionary |

Thanks for the response. I am now testing this BC with rhoSimpleFoam.
