A classical theory of an isolated droplet mass and heat transfer to the surrounding air is adapted to analyze the evaporative behavior of water droplets flowing through gas turbine inlet ducts. The theory is extended to explain the interaction between a single droplet and the other droplets and the interaction with the carrying air. The present method is applied to predict the performance of inlet air cooling systems for small-sized gas turbines. It is found that small-sized gas turbines can not get enough cooling effect by water injection equivalent to the surrounding air saturation, because of short residence time of water droplets in the ducts; but small amount of over-saturated spray helps to achieve high cooling efficiency of over 90%, in less dependent of climatic conditions.
