Liquid-Gas Interface Stability in Inverted Liquid Piston Air Compressor

This experimental research focuses on the stability of the liquid-gas interface in an inverted liquid piston air compressor. Here, a column of water rests on a stationary piston, and porous media is added to increase heat transfer and thus efficiency. It was found that wider spacing, longer lengths, and smaller diameters of porous media result in greater stability. The results will help determine potential applications and operating conditions for this technology.
