The present study aims to offer a microscopic description of the behavioral pattern of a gas system interacting with a mobile wall based on Clausius model and on its ensuing models. Starting from this analysis, the first part of this study comes to validate the equations published in the early works in Finite Speed Thermodynamics, while the second part deals with the interaction between the gas system and a mobile wall set off at a certain angle to its moving trajectory. The study conclusions are applies to the analysis of the interaction between gas or vapor systems and the mobile units of rotating devices.
