Pushkarevab} UDC 533.24:621.593 By means of a numerical experiment with the example of methane, we analyze the features of the working process of a reciprocating expander with heat release associated with condensation, friction, and external heat exchange. The influence of the technical characteristics of expanders and inlet gas parameters is also considered. a}State Polytechnical University, 29 Politekhnicheskaya Str., Saint-Petersburg, 195251, Russia; b}Joint Power and Nuclear Research Institute (Sosny), National Academy of Sciences of Belarus, 99 Acad.
