Today an increasing use of regenerative energy leads to stronger power fluctuations that have to be corrected by conventional power plants. One possible method to augment the power output of a stationary gas turbine is the injection of water into the compressor inlet, also called high-fogging. The investigation of water droplets in high-fogging applications in the compressor of stationary gas turbines arises from the increasing need of rapid correction of power fluctuations. The present paper focuses on the numerical simulation of the droplet behavior within one compressor stage. A numerical model is presented to describe the motion of the droplets through the ambient gas flow, the impact and splashing on the blade surface and the propagation of the resulting wall film. Furthermore, important parameters of the numerical simulation and their influence on the resulting wall film are discussed in detail.
