Analysis of Liquid-Heating Process in the Course of Compression in the Working Cavity of the Compressor Section of a Hybrid Piston Power Machine

Abstract

An analysis of the processes involved in heating of the liquid present above a piston in the working cavity of the compressor section of a positive-displacement hybrid power machine is given. On the basis of the general fundamental laws of conservation of energy and mass a thermodynamic calculation of the parameters of a two-phase, two-component open thermodynamic system with deformation and thermal interaction of phases is carried out. The influence of deformation work, external heat exchange, and direct-contact heat transfer on the variation of the temperature of the liquid is determined.
