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:

$$\text{Q\_{flow} = text{port\_a.Q\_{flow}} text{port\_a.Q\_{flow}} + text{port\_b.Q\_{flow}} = 0 text{port\_a.T} = text{port\_b.T}}$$

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)

Behavior

$$\begin{array}{rl}\mathtt{port}\mathtt{\_}\mathtt{a}\mathtt{.}\mathtt{T}\left(t\right)& =\mathtt{port}\mathtt{\_}\mathtt{b}\mathtt{.}\mathtt{T}\left(t\right)\\ \mathtt{port}\mathtt{\_}\mathtt{a}\mathtt{.}\mathtt{Q}\mathtt{\_}\mathtt{flow}\left(t\right)+\mathtt{port}\mathtt{\_}\mathtt{b}\mathtt{.}\mathtt{Q}\mathtt{\_}\mathtt{flow}\left(t\right)& =0\\ \mathtt{Q}\mathtt{\_}\mathtt{flow}\left(t\right)& =\mathtt{port}\mathtt{\_}\mathtt{a}\mathtt{.}\mathtt{Q}\mathtt{\_}\mathtt{flow}\left(t\right)\end{array}$$
