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=Gi⋅dTi
Gi= Material.k⋅A L⋅AciAci>0G__offelse
dTi=T__ai−T__bi
Heat conductance G__off is used for the heat path without heat flow.
