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 ​

NameDescriptionUnits
ΔTK
QW

Behavior ​

ΔT(t)=solid.T(t)−fluid.T(t)solid.Q(t)=Q(t)fluid.Q(t)=−Q(t)ΔT(t)=Q(t)Rc(t)
