Detailed Description

Heat transfer coefficient calculation that employs a fixed reference temperature.

The heat transfer coefficient is calculated by:

\[ h = \frac{q}{T_{ref} - T_p} \]

where

$ h $ = Heat transfer coefficient [W/m^2/K]
$ q $ = Heat flux [W/m^2]
$ T_{ref} $ = User-specified reference temperature [K]
$ T_p $ = Patch temperature field [K]
Usage
Minimal example by using system/controlDict.functions: 
heatTransferCoeff1
{
    // Inherited entries
    ...

    // Mandatory entries
    htcModel        fixedReferenceTemperature;
    Tref            <scalar>;
}

where the entries mean:

Property Description Type Reqd Deflt
type Model name: fixedReferenceTemperature word yes -
Tref User-specied reference temperature scalar yes -
