Gas turbine inlet fog / overspray cooling is considered as a simple and effective method to increase power output. To help understand the water mist transport in the compressor flow passage, this study conducts a computational simulation of wet compression in a single rotor-stator compressor stage using the commercial code, Fluent. A sliding mesh scheme is used to simulate the stator-rotor interaction in a rotating frame. Previous researchers have modeled wet compression using DPM (Discrete Phase Model), where spray amount is very small (1–2%). Compressor washing is also becoming a new interest in the wet compression technology, which involves much higher amount of water (10–15%), which is not easy to handle with DPM. It can be done by multiphase model. To start compressor washing it is important to validate wet compression (1–2% spray) using DPM and the same using multiphase. This study takes the initial step to compare these two models, however multiphase model needs further development to perform an apple to apple comparison with DPM.Copyright © 2013 by ASMEread more
