PrescribedHeatFlow
Prescribed heat flow boundary condition

Description
This model allows a specified amount of heat flow rate to be "injected" into a thermal system at a given port. The amount of heat is given by the input signal Q_flow into the model. The heat flows into the component to which the component PrescribedHeatFlow is connected, if the input signal is positive.
If parameter alpha is <> 0, the heat flow is multiplied by (1 + alpha*(port.T - T_ref)) in order to simulate temperature dependent losses (which are given with respect to reference temperature T_ref).
