Thermal contact conductance is an important parameter in a wide range of thermal phenomena, and consequently a large number of experimental, numerical and statistical investigations have been presented in literature. An analysis of thermal contact resistance is carried out to predict heat transfer between nominally flat, parallel rough surfaces in contact, in absence of interstitial conductive media (i.e. in vacuum), by means of a statistical approach. The rough surface is described through a probabilistic model based on the peak height variability and invariant asperity curvature radius

Abstract
Thermal contact conductance is an important parameter in a wide range of thermal phenomena, and consequently a large number of experimental, numerical and statistical investigations have been presented in literature. An analysis of thermal contact resistance is carried out to predict heat transfer between nominally flat, parallel rough surfaces in contact, in absence of interstitial conductive media (i.e. in vacuum), by means of a statistical approach. The rough surface is described through a probabilistic model based on the peak height variability and invariant asperity curvature radiusFile in questo prodotto:
