lumpedMassWallTemperature

Description

The lumpedMassWallTemperature is a boundary condition that provides a lumped mass model for temperature.

It considers a single temperature value for the whole patch and evaluates the temperature evolution using the net heat flux into the patch.

Usage

The condition requires entries in both the boundary and field files.

Boundary file

<patchName>
{
    type            patch;
    ...
}

Field file

<patchName>
{
    // Mandatory entries
    type            lumpedMassWallTemperature;
    Cp              <scalar>;
    mass            <scalar>;

    // Inherited entries
    ...
}

where:

Property	Description	Type	Required	Default
type	Type name: lumpedMassWallTemperature	word	yes	-
Cp	Heat capacity [J/kg/K]	scalar	yes	-
mass	Total mass [kg]	scalar	yes	-

The inherited entries are elaborated in:

• temperatureCoupledBase.H
