Liquid piston gas compression

摘要: Abstract A liquid piston concept is proposed to improve the efficiency of gas compression and expansion. Because a can conform an irregular chamber volume, surface area volume ratio in be maximized using piston. This creates near-isothermal operation, which minimizes energy lost heat generation. eliminates leakage replaces sliding seal friction with viscous friction. The also used as medium carry into out chamber. simulation presented transfer frictional forces for reciprocating In application air compressor, pressure 9.5:1 cycle frequency 20 Hz, decreased consumption by 19% over exhibited total 83% 70% respectively. demonstrated significant improvements comparison conventional gain was accomplished through increasing during
