modelFixedHeatFlow
Information
Hypothesis and equations
This model allows a specified amount of heat flow rate to be "injected" into a thermal system at a given port. The constant amount of heat flow rate Q_flow is given as a parameter. The heat flows into the component to which the component FixedHeatFlow is connected, if parameter Q_flow is positive.
If parameter alpha is > 0, the heat flow is mulitplied by (1 + alpha*(port.T - T_ref)) in order to simulate temperature dependent losses (which are given an reference temperature T_ref).
