Wet compression technology is one of the main means to improve the output power and efficiency for modern high-performance gas turbines.The progress and application of wet compression technology were summarized at home and abroad,the evaporation characteristics and movement pattern of droplets,the interaction mechanism between droplets and the wall,the heat and mass transfer between droplets and air,and the influence of droplets parameters on overall aerodynamic performance and stable operation range of compressors were expounded.At the same time,the wet compression system,atomization method,nozzle structure and system application status for gas turbines were discussed and analyzed.Based on the current research focus and development trend,and combined with author's continued attention to the developments of various gas turbine technologies,four research directions of wet compression technology were put forward,including the wet compression full three-dimensional simulation and experimental measurement,droplets movement and evaporation rule,wet compression performance matching method of main components,and the relationship among influencing factors of nozzle atomization.
