Characterization of a medium velocity deluge nozzle for offshore installations

It is important to study the characteristics of nozzle deluge spray comply with standards developed by petroleum industry for offshore installations in Norway. Due stochastic nature decomposition processes and geometrical features within nozzle, has a complex flow field. Since field determines performance spray, present performs an experimental characterization medium velocity validation computational fluid dynamics (CFD) models. The experiment was conducted maximum supply water pressure 8.0 bar (g), which identical operating pressures installations. Formerly, studies or sprinkler were mostly targeted on residential usage lower pressures. I utilized laser-based shadow imaging system capture high-speed images, later processed MATLAB. A linear patternator used validate results technique. played role determining spray. In addition, significantly affected size distributions droplets, applied density (volume flux), area coverage. However, Sauter mean diameter did not vary azimuthal radial position droplet inner region measurements obtained this can be estimate extinguishing efficiency elevated Deviations between technique are discussed discrepancies discussed.
