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.
This model is identical to
Modelica.Thermal.HeatTransfer.Sources.PrescribedHeatFlow, except that
the parameters alpha and T_ref have
been deleted as these can cause division by zero in some fluid flow models.
