Detailed Description

Calculates and writes the estimated flow heat transfer coefficient at wall patches as the volScalarField field 'wallHeatTransferCoeff' using Reynolds Analogy.

Reynolds Analogy model, given by:

$htc = 0.5 \rho C_p |U_{ref}| C_f$

where

	=	Density [kg/m^3]
	=	Specific heat capacity [m^2/K/s^2)]
	=	Far field velocity magnitude [m/s]
	=	Skin friction coefficient []

All wall patches are included by default; to restrict the calculation to certain patches, use the optional 'patches' entry.

Example of function object specification:

    ReynoldsAnalogy1
    {
        type       wallHeatTransferCoeff;
        libs       ("libfieldFunctionObjects.so");
        model      ReynoldsAnalogy;
        ...
        region     fluid;
        patches    (".*Wall");
        rho        1.225;
        Cp         1005;
        Uref       1.0;
    }

Usage

Property	Description	Required	Default value
`type`	type name: wallHeatTransferCoeff	yes
`model`	Type name: ReynoldsAnalogy	no	kappaEff
`patches`	List of patches to process	no	all wall patches
`region`	Region to be evaluated	no	default region
`rho`	Density	yes
`Cp`	Specific heat capacity	yes
`Uref`	Reference velocity magnitude	yes	no

Note: Cp and rho are required only for incompressible flow calculations.
