Spray Combustion Spectral Characteristics [PDF]
ASME 1997 Turbo Asia Conference, 1997 Spray combustion in an axisymmetric combustor is analyzed numerically with three droplet models; (1) Ranz and Marshall droplet law (2) droplet laws by canonical droplet theory, accounting for the droplet blowing effect and flow convecting effect, and (3) renormalized canonical droplet theory, which accounts for the drop-drop short range interaction as ...

Spray Characteristics Analysis of Fire Sprinkler Spray with Image Processing
International Journal of Fire Science and Engineering, 2023 Sprinkler systems are effective in suppressing fires during their initial stages. The ability of a sprinkler to suppress a fire is contingent on the density, size, and velocity of the droplets it emits. In this study, a high-speed camera was employed to measure the size and velocity of droplets generated by a sprinkler head with a K-factor of 80.

Characteristics of Spot Spraying and Continuous Spraying Systems
AgricultureThis paper studied the atomization characteristics of different spray nozzles under the spot spraying method and designed a test system for the atomization characteristics. First, the effective spray height range was determined based on the effective droplet size of 106–403 μm, the spray height of 200–500 mm, the operating speed of 0.5–1 m/s, and the ...
