A study of fast reactions in nozzle type reactors
A study of fast reactions in three nozzle reactors of the same geometry has been investigated. The nozzle reactors are 0.55 x 10¯³ m³ 1.52 x 10¯³ m³ and 5.13 x 10¯³ m³ respectively, and flow visualizations have been studied by injecting a tracer into the inlet and at the walls of the reactors. A …

Effect of liquid properties (water and lime juice) on spray characteristics of deflected flat spray nozzle (AL-75)
Nowadays, the application of the nozzle has been widely used in the industry. The main factor that influences the spray is pressure of the liquid and air, type of nozzle, type of spray and the viscosity of the liquid. The problem in this research is to determine minimum liquid pressure used for …

EVALUATION OF FUNGICIDE APPLICATION AT LATE BLOOM FOR THE CONTROL OF SCLEROTINIA STEM ROT IN RAPESEED (CANOLA)
… late bloom application. Rate of application and nozzle type were varied in a few tests. Disease levels were high enough to warrant collection and analysis of disease incidence data at 4 of 5 locations in 1987 and 5 of 10 locations in 1988. Late bloom application of benomyl at the recommended rate …

Development of deflector flat spray nozzle with mixed of water and organic citric acid for emissions trap and cooling in the kitchen hood ventilation system
… this study compared the existing (conventional) nozzles in the market such as KSJB model (water spray) and AL75 model (mist spray). Then, this study compared two nozzle designs of deflector nozzles that is ND2.5 A1.0 and ND2.5 B1.0. The difference between these two nozzles is the swirl angle. The …

Evaporating crossflow sprays in gas-solid flows
… The geometric and operating parameters, such as nozzle size, nozzle type, injection angle, jetting velocity, and solids loading are studied in the experiments. The experimental study shows that the loading of solid particles in mainstream can significantly shorten the penetration length and alter …

Computational fluid dynamics modeling of a large bore two-stroke natural gas engine
… of a real valve, a simple converging-diverging type virtual valve is suggested for three dimensional engine simulation with high pressure injection. The results indicated that the suggested converging-diverging nozzle type virtual valve produces practically identical downstream fuel jet with the …
