A cooling suction air with water spray has been used for the gas turbine. The cooling efficiency depends on spray properties and surrounding conditions. The aim of this study is to know spray properties and to clarity an influence of spray nozzle type on the cooling efficiency. A Phase Doppler Anemometry (PDA) is used for measurements. This measurement system is able to measure size and velocity of each droplet. A pin type nozzle, two different hole type nozzles are tested. The distribution of spray properties for the pin type nozzle becomes asymmetry due to the existence of pin. Its spray spreads widely and has broad size distribution in all spray area. Spray spreading area of hole type nozzles is narrow. Small particles gather on the spray center and large particles gather in the spray outer edge. Properties of each nozzle are also discussed for evaluating the cooling efficiency.
