“…Chaker [8][9][10] comprehensively introduced the physics and engineering of the fogging process, droplet measurement methods, droplet kinetics, and the duct behaviour of droplets, from a gas turbine perspective. Hain [11] discussed the design and operation of real fogging systems, namely: single droplet, mono-and poly-fraction fog evaporation; influence of flow turbulent intensity; fog cloud shape and dimensions; poly-fraction fog evaporation in the wide range of ambient conditions; over-spray and under-spray operation of the fogging system. Spray cooling is also increasingly used to achieve immediate cooling and to enhance the thermal comfort in outdoor and indoor environments, since it is efficient and environmentallyfriendly [12,13].…”
