A model has been developed to investigate the evaporation behavior of water droplets in a uniform duct flow under gas turbine environments. It is assumed that the change of water droplet temperature is caused by convective heat transfer through droplet surface. The temperature of a water droplet has been calculated by treating the droplet as a lumped mass with a representative temperature uniformly distributed in the droplet. The proposed model consists of two steps. The 1st step is the heat transfer calculation between a water droplet and surrounding air flow and the 2nd step is the calculation to take the latent heat of vaporization into consideration. The evaporation rate is calculated based upon mass transfer between water droplet and surrounding air flow.
