Sensors.HeatFlowSensor ​

Measures the rate of heat flow between two thermal connection points.

This component represents an ideal thermal sensor that quantifies the heat flow rate passing from port_a to port_b. It introduces no temperature drop between its connection points (port_a.T = port_b.T) and has no thermal energy storage (port_a.Q_flow + port_b.Q_flow = 0). The output signal Q_flow represents the heat flow rate from port_a to port_b.

The key behaviors are defined by:

Q_{flow} = \text{port_a.Q_{flow}} \text{port_a.Q_{flow}} + \text{port_b.Q_{flow}} = 0 \text{port_a.T} = \text{port_b.T}

Usage ​

ThermalComponents.Sensors.HeatFlowSensor()

Connectors ​

  • Q_flow - This connector represents a real signal as an output from a component (RealOutput)

  • port_a - This connector represents a thermal port with temperature and heat flow as the potential and flow variables, respectively. (HeatPort)

  • port_b - This connector represents a thermal port with temperature and heat flow as the potential and flow variables, respectively. (HeatPort)
