Hello forum,
Why in OpenFOAM there are Wall Functions formulation only for Turbulence Equations and not for Energy Equation and Momentum Equations?! Thanks in advance |

That's the way how it works!

If you use a high Reynolds number tubulent model than the turbulence model equation are not solved in the wall near region (see wall functions), but the RANS equations are solved everywhere. hth |

thank you very much Stefan,
but why we find also wall function formulations for Energy equation?! (see also Fluent manual..). For example Reynolds' analogy between momentum and energy transport gives a similar logarithmic law for mean temperature. So there is a law-of-the-wall for mean velocity, but also law-of-the-wall for the temperature. Why that is not implemented in OpenFOAM?! Thanks in advance |
