Detailed Description

Heat exchanger source model, in which the heat exchanger is defined as a selection of cells.

The total heat exchange source is given by:

$Q_t = e(\phi, \dot{m}_2) (T_2 - T_1) \phi c_p$

where:

	=	total heat source
$e(\phi,\dot{m}_2)$	=	effectiveness table
$\phi$	=	net mass flux entering heat exchanger [kg/s]
$\dot{m}_2$	=	secondary mass flow rate [kg/s]
	=	primary inlet temperature [K]
	=	secondary inlet temperature [K]
	=	specific heat capacity [J/kg/K]

The distribution inside the hear exchanger is given by:

$Q_c = \frac{V_c |U_c| (T_c - T_{ref})}{\sum(V_c |U_c| (T_c - T_{ref}))}$

where:

	=	source for cell
	=	volume of the cell [m^3]
	=	local cell velocity [m/s]
	=	local call temperature [K]
$T_{ref}$	=	min or max(T) in cell zone depending on the sign of Q_t [K]

Usage

Example usage:

effectivenessHeatExchangerSource1
{
    type                    effectivenessHeatExchangerSource;

    select                  cellZone;
    cellZone                porosity;

    secondaryMassFlowRate   1.0;
    secondaryInletT         336;
    primaryInletT           293;

    faceZone                facesZoneInletOriented;

    effectiveness           <function2>;
}

Note:

The effectiveness Function2 is described in terms of the primary and secondary mass flow rates and has the same units as the secondary mass flow rate and kg/s for phi.
faceZone is the faces at the inlet of the cellzone, it needs to be created with flip map flags. It is used to integrate the net mass flow rate into the heat exchanger
