Wall Heat Transfer and Storage Effects on the Thermal Dynamics of Otis-Effect Gas Compression Processes

Accurate and realistic modeling of the gas compression process in piston cylinder systems is of fundamental importance in various power and control applications. As a result, this dispersive-absorptive process (Otis, 1974; Pourmovahed and Otis, 1984; and Otis and Pourmovahed, 1985) has been analyzed in various theoretical and experimental studies, from both thermodynamic and system dynamics viewpoints. In a consistent extension of previous work to system boundaries characteristic of many practical devices, heat transfer and energy storage associated with the confining cylinder walls may be shown to exert a significant effect on the dynamics of the Otis-effect gas compression problem.
