Evaluation of the real contact area in three-body dry friction by micro-thermal analysis [PDF]
, 2009 Many tribological properties and wear mechanisms occurring on the micro-and nanoscale are strongly controlled by the so-called real contact area (Ar) which is a small fraction of the nominal or apparent contact area (Aa). The determination of Ar is often

Effects of pressure on thermal contact resistance for rough mating surfaces
ASEAN Journal on Science and Technology for Development, 2017 Thermal contact resistance has been studied experimentally to investigate the effect of pressure between two aluminium or two brass rough surfaces at three different heat flux levels. Three different rough surfaces are considered in the range of 2.63 to

Thermal Contact Resistance Between Two Nanoparticles [PDF]
Journal of Computational and Theoretical Nanoscience, 2008 We compute the thermal conductance between two nanoparticles in contact based on the Molecular Dynamics technique. The contact is generated by letting both particles stick together under van der Waals attractions. The thermal conductance is derived from the fluctuation-dissipation theorem and the time fluctuations of the exchanged power.
