Abstract:An engineering method for calculating the air element is offered with air damping due to the discrete switching of active and additional gas volumes. Heat exchange with the environment is described with the polytropic process law. The analytical dependence determining the growth of entropy in irreversible processes during volumes switching is described. The thermodynamic parameters of gas in general case are functionals from change history of the active volume. It is shown that steady operating mode is feasibl… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
