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:

\[Q = \text{node_a.Q} \text{node_a.Q} + \text{node_b.Q} = 0 \text{node_a.T} = \text{node_b.T}\]

Usage

ThermalComponents.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)

Behavior

\[ \begin{align} \mathtt{node\_a.T}\left( t \right) &= \mathtt{node\_b.T}\left( t \right) \\ \mathtt{node\_a.Q}\left( t \right) + \mathtt{node\_b.Q}\left( t \right) &= 0 \\ Q\left( t \right) &= \mathtt{node\_a.Q}\left( t \right) \end{align} \]
