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 node_a to node_b. It introduces no temperature drop between its connection points (node_a.T = node_b.T) and has no thermal energy storage (node_a.Q + node_b.Q = 0). The output signal Q represents the heat flow rate from node_a to node_b.

The key behaviors are defined by:

$$\text{Q = text{node\_a.Q} text{node\_a.Q} + text{node\_b.Q} = 0 text{node\_a.T} = text{node\_b.T}}$$

Usage

HeatFlowSensor()

Connectors

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

• node_a - This connector represents a thermal node with temperature and heat flow as the potential and flow variables, respectively. (Node)

• node_b - This connector represents a thermal node with temperature and heat flow as the potential and flow variables, respectively. (Node)

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