Multi Thermal Contact Resistance

Multiple thermal contact resistance between two materials

 Description The Multi Thermal Contact Resistance component models multiple Thermal Contact Resistances. The total number of Thermal Contact Resistance components is determined by the Nodes parameter. The following example uses Thermal Contact Resistance components to explain the behavior of Thermal Contact Resistance component.
 Equations   (For details, see Thermal Contact Resistance  help).
 Variables (For details, see Thermal Contact Resistance  help).

 Name Units Condition Description Modelica ID $\mathrm{port_a}\left[i\right]$ - i-th thermal port a port_a[i] $\mathrm{port_b}\left[i\right]$ - i-th thermal port b port_b[i] $\mathrm{A_input}$ - if use Apparent contact area input is true. Apparent contact area of each node is defined by Real signal input. A_input $\mathrm{Aratio_input}$ - if use Area ratio input is true. Area ratio $\frac{\mathrm{A__c}}{A}$ of each node is defined by Real signal input. Aratio_input $\mathrm{L_input}$ - if use Void space thickness input is true. Thickness of the void space is defined by Real signal input. L_input
