Experimental Investigation of Impacts of Initial Pressure Levels on Compression Efficiency and Dissolution in Liquid Piston Gas Compression

Understanding how the pressure level affects efficiency of liquid piston gas compression is essential for a greater applicability technology in compressed air energy storage. To explore impacts, starting at three different initial levels (1, 2, 3 bar) with ratio 2 performed, and isothermal efficiencies are affected depending on pressures analyzed. Under experimental conditions, higher leads to lower efficiency. Air dissolution during also investigated because chamber pressure-varying liquid-containing environment, where solubility changes process. Evaluating critical as it output when expanded regenerate energy. The mass retrievable volume after expansion quantified based Henry’s law. For pressure, proportional reduction percentages expected. This trend decreasing less than originally intended stored retrieved discharging
