Effect of Integrating Metal Wire Mesh with Spray Injection for Liquid Piston Gas Compression

Heat transfer enhancement techniques used in liquid piston gas compression can contribute to improving the efficiency of compressed air energy storage systems by achieving a near-isothermal process. This work examines effectiveness simultaneous use two proven heat techniques, metal wire mesh inserts and spray injection methods, compression. By varying dimension pressure spray, comparative study was performed explore plausibility additional improvement. The addition an insert help abating temperature rise when does not take much space or flowrate is low. At higher pressure, however, spacious lead less efficient abatement. because distract free-fall droplets hinder their speed. In order analytically account for compromised cooling effects droplets, Reynolds number, Nusselt coefficients are estimated under test conditions. number free-falling droplet be more than 1000 times that stationary droplet, which results 3.95 4.22 differences coefficients.
