Energy conversion of thermoacoustic engines with evaporation and condensation

This study investigated the energy conversion of a thermoacoustic engine using wet regenerator for interconversion heat flux density and work density. According to first law thermodynamics, local can be described source corresponding gradient First, we analytically separated phenomena related water evaporation condensation. Thereafter, experimentally only gas, then that The data obtained were compared with analytical results. experimental results showed good agreement. Furthermore, condensation, which was determined both experimentally, higher than gas by maximum factor 4.5.
