ThermalResistor

Lumped thermal element, with resistance, transporting heat without storing it.

This component extends from Element1D

Usage

ThermalResistor(R)

Parameters:

Connectors

• node_a - (Node)
• node_b - (Node)

Variables

Behavior

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