Abstract
The breakup of a laminar liquid jet by coaxial non-swirling and swirling air streams
Highlights
Spray systems are widely used in many areas of life such as the injector of internal combustion (IC) engine, for coating surfaces, and drug delivery to human air passages, for example
When the aerodynamic Weber number increases, the averages of breakup lengths and the axial distances for the first droplet separation reduce, except for the swirling flow cases with low aerodynamic Weber numbers. This can be explained on the basis of the increase of the shear stress acting on the water-air interface, which leads to a more significant destabilization of the liquid jet
In terms of the swirling flow cases with low aerodynamic Weber numbers, the breakup length of the co-annular swirling jet tends to increase as the aerodynamic Weber number grows
Summary
Spray systems are widely used in many areas of life such as the injector of internal combustion (IC) engine, for coating surfaces, and drug delivery to human air passages, for example. There are many types of atomizers such as pressure, rotary, air-assist, air blast atomizers, etc. The liquid jet will experience a pressure drop and break into drops and ligaments after it leaves the nozzle [1]. The size and velocity distribution of the droplets plays a key role in the spray system performance. It is necessary to gain better understanding of how the droplets and ligaments are formed in the spray. To make the best use of a spray system, it is important to make the process of formation of droplets and ligaments controllable
