Detailed Description

Model for heat exchange. Requires specification of an ambient temperature with which to exchange heat, and a model for the heat transfer coefficient (htc) and the area per unit volume (AoV). These are then used to apply the following source to the energy equation:

$-htc*AoV*(T_a - T)$

If the semiImplicit option is set, then this becomes:

$-htc*AoV*(T_a - T) + htc*AoV/Cp*h - Sp(htc*AoV/Cp, h);$

Usage

Example usage:

heatTransfer
{
    type            heatTransfer;

    heatTransferCoeffs
    {
        selectionMode   cellSet;
        cellSet         c0;

        semiImplicit    no;

        Ta              300;

        type            constant;

        AoV             200;
        htc             10;
    }
}
