Thermal Conductance Properties

Thermal Conductance Properties

Thermal Conductance Properties

(OP)
I am defining contact properties for conducting surfaces. In the boxes where I am required to mention the conductance at zero clearance, what goes in there is it the thermal conductivity of the slave or the master surface. Also what goes in the clearance box for zero conductivity? In my case the surfaces are in full 100% contact with no clearance. Thanks  

RE: Thermal Conductance Properties

Regardless of existence of clearance, you can always define the gap conductance as a function of clearance. At least two data lines must be specified. When gap conductance is defined as a function of clearance, the value of the conductance drops to zero immediately after the last data point; therefore, there is no heat conductance when the clearance is greater than the value corresponding to the last data point.

for example, you can define it in table format so that in your input file it looks like:

*Gap Conductance
10.0, 0.
2., 0.01
0,0.1
