DESIGN, DEVELOPMENT & EXPERIMENT ON AIR ASSISTED ATOMIZER

MECHANICAL ENGINEERING

The transformation of bulk liquid sprays and other physical dispersions of small particles in a gaseous atmosphere are of importance in several industrial processes and have many other applications in agriculture, meteorology, and medicine. Numerous spray devices have been developed, and they are generally designated as atomizers. The process of atomization is one in which a liquid jet or sheet is disintegrated by the kinetic energy of the liquid itself, or by exposure to high-velocity air or gas, or as a result of mechanical energy applied externally through a rotating or vibrating device. Combustion of liquid fuels in diesel engines, spark ignition engines, gas turbines, rocket engines, and industrial furnaces is dependent on effective atomization to increase the specific surface area of the fuel and thereby achieve high rates of mixing and evaporation. The process of generating drops is called atomization. The process of atomization begins by forcing liquid through a nozzle. The process of atomization is a process where a liquid jet or sheet is broken up by the kinetic energy of the liquid itself or by exposure to high velocity air or gas. These ligaments then break up further into very small “pieces” which are usually called drops, droplets, or liquid particles.
