“…In numerical thermomechanical simulations of the CHT, the microscale interface could be created stochastically using surface topography descriptors. 32,33 They could be also monitored by optical profilometry 34 for particular applications or by 2D stylus-based surface profilers. 35 The stochastic approaches for metal-metal contacts could be generalized to approximate the electrical contact resistance (ECR) in electrical power connectors.…”

An accurate understanding of the thermal contact conductance (TCC) is imperative for the enhancement of the performance and service life of metallic cylindrical joints. However, the evaluation of the TCC between conforming cylindrical solids is quite intricate, as it depends on the temperature, pressure, roughness, relative sliding speed, and thermophysical properties of solids. Instead of generating contacting surfaces stochastically, in this communication, an experimental setup in the lab-scale consisting of a stationary cylinder and a sliding hot disk has been fabricated in which temporal evolutions of the temperature on both solids are recorded by thermocouples.
