Effect of Surface Curvature on Contact Resistance between Abutting Cylinders

Mayer, Michael.


  • Abstract: Due to the microscopic roughness of contacting materials, an additional thermal resistance arises from the constriction and spreading of heat near contact spots. Predictive models for contact resistance typically consider abutting semi-infinite cylinders subjected to an adiabatic boundary condition along their outer radius. At the nominal plane of contact an isothermal and circular conta... read more
