ConvectiveResistance

Lumped thermal element for heat convection with resistance as an input.

This component extends from ConvectiveElement1D

Usage

ConvectiveResistance()

Connectors

• solid - (Node)
• fluid - (Node)
• Rc - This connector represents a real signal as an input to a component (RealInput)

Variables

Behavior

\[ \begin{align} \mathtt{{\Delta}T}\left( t \right) &= \mathtt{solid.T}\left( t \right) - \mathtt{fluid.T}\left( t \right) \\ \mathtt{solid.Q}\left( t \right) &= Q\left( t \right) \\ \mathtt{fluid.Q}\left( t \right) &= - Q\left( t \right) \\ \mathtt{{\Delta}T}\left( t \right) &= Q\left( t \right) \mathtt{Rc}\left( t \right) \end{align} \]
