Effects of Droplet Size on Transient Behavior of after Fogging Process

Abstract:

Gas turbine cycles with after fogging where water is injected after compressor could offer enhanced efficiency compared to inlet fogging system due to higher water injection ratio. In this work the after fogging process is modeled based on the evaporation of droplets. Transient behaviors of the process are investigated with analytic expressions obtained by considering heat and mass transfer and thermodynamic relations. Effects of droplet size on the transient behaviors of important system variables are thoroughly investigated including diameter and mass of droplets, temperature and density of air, and mass flux and heat transfer from the droplets.
