Summary for: FlowHeatSinkConnection < Node2NodeConnection

Class summary

FlowHeatSinkConnection Coolant flow acting as a heat sink.

The FlowHeatSinkConnection class is intended to model heat rejection into a coolant, with the coolant temperature rise equal to heat_flow ** this.coolant_mass_flow ** this.coolant_specific_heat, where the temperature rise is equal to the temperature difference between this.node1 and this.node2.

Please note that this model is very simple, and e.g. differing coolant temperatures in different parts of the coolant circuit are not modelled, unless multiple FlowHeatSinkConnections are used.

Also note that the model behaves in a fashion that may be counter-intuitive to some. Let us use an axial flow in the airgap as an example, with the average fluid temperature in the airgap modelled by a single ThermalNode. In this case, a FlowHeatSinkConnection would be set up between the airgap node and a node representing the inflow temperature of the coolant. Furthermore, the temperature of the airgap node would then also equal the coolant temperature on the outflow side. Finally, the direction of the heat flow in the FlowHeatSinkConnection would obviusly be from the airgap node to the inflow node - i.e. opposite to the fluid velocity and actual direction of energy transfer.
