Analysis of Liquid Piston Compressibility in the Two-Stage Hybrid Positive-Displacement Machine

The effect of liquid compressibility in the two-stage piston hybrid positive-displacement machine with a liquid piston was considered. Based on the volume conservation equation, we developed a calculus methodology for the liquid compressibility during gas compression in the second stage of the compr...
