Variable Thermal Conductor

Multiple Variable Thermal Conductor with normalized contact area ratio of each node, input from real vector signals.

  

Description

The Variable Thermal Conductor component is used for connecting two Multi- components.

This component can take account of normalized contact area ratio between port_a and port_b input from real vector signal, Ac.

The following image illustrates the behavior of the Variable Thermal Conductor component.

Equations

Qflowi=GidTi

 Gi= Material.kA LAciAci>0G__offelse

 dTi=T__aiT__bi

Heat conductance G__off is used for the heat path without heat flow.
