Detailed Description

Calculates the estimated flow heat transfer coefficient at wall patches as the volScalarField field 'kappaEff' using one of equations below.

kappaEff model, given by:

\[ htc = \rho*C_p*({\frac{\nu}{Pr} + \frac{\nu_t}{Prt}}) \]

kappaEff model with characteristic length, given by:

\[ htc = \rho*C_p*({\frac{\nu}{Pr} + \frac{\nu_t}{Prt}})\frac{1}{L_{char}}; \]

where

$ rho $ = Density [kg/m^3]
$ Cp $ = Specific heat capacity [m^2/K/s^2)]
$ Pr $ = Fluid laminar Prandtl number []
$ Prt $ = Fluid turbulent Prandtl number []
$ Lchar $ = Characteristic length [m]

Example of function object specification: 

    kappaEff1
    {
        type        wallHeatTransferCoeff;
        libs        ("libfieldFunctionObjects.so");
        model       kappaEff;
        ...
        region      fluid;
        patches     (".*Wall");
        rho         1.225;
        Cp          1005;
        Pr          0.707;
        Prt         0.9;
    }
    kappaEff2
    {
        type        wallHeatTransferCoeff;
        libs        ("libfieldFunctionObjects.so");
        model       kappaEff;
        ...
        region      fluid;
        patches     (".*Wall");
        rho         1.225;
        Cp          1005;
        Pr          0.707;
        Prt         0.9;
        Lchar       0.001;
    }
