Compressor inter_stage water spraying is a ideal intermediate cooling technique for marine gas turbines,and the atomization technique used to generate the droplets is the key to success.The purpose, equipment used, measuring system, spraying mechanism, test schemes and test procedure of experimental research on water spraying over simulated compressor inter_stage flow field of marine gas turbine compressor are reported. Wind tunnel experiments were made with nozzles. Different ways of spraying pressure loses and atomization characteristics of nozzles at various wind tunnel velocities are detailed. An optimal water spraying scheme was established for gas turbine(S1A02) through analysis of experimental results.
