The effective conductivity of material systems consisting of contacting particles is studied computationally using a model of monodisperse circular disks. The electrical or thermal conductivity is computed by modeling the relevant mechanical contact problem followed by a steady-state conduction analysis. The interparticle contact resistance is incorporated via the introduction of gap conductanc...

Ahstraet--ln many cooling situations, permanent attachment of fins to heat dissipating devices is undesirable yet htrge mechanical loads, important in reduction of thermal contact resistance, are not permitted. This work considers the interface between a low-force pressed-on fin and a heat source in boiling heat transfer; the thermal contact resistance and how the interface region may be used t...
