Atomization technology is used in a wide variety of industrial applications for spraying liquids and powders. It is particularly useful for spraying difficult to spray materials such as strain hardening, non-Newtonian, or high viscosity fluids with tight particle size distributions and tunable droplet sizes. Typical spray methods like air, hydraulic and pneumatic atomization are not able to maintain these characteristics with a more diverse set of fluids and may fail to provide a spray that is uniform in diameter and shape. This is why a variety of atomization technologies has been developed to solve these problems.There are https://en.smooretech.com/ that influence the nature and quality of an atomized spray including the type of working liquid, nozzle design, the injection settings and the superficial kinetics. The atomization process begins when the fluid is injected through an orifice and develops into ligaments or globules of liquid. The formation of these ligaments or globules of fluid is due to the balance in distinctive features of the atomization system. The force of liquid jet atomization is determined by the energy available in the working liquid and the surface tension of the liquid and the pressure variation within the surrounding air. This force is augmented by the effect of other forces namely the aerodynamic and internal impact forces.The atomization process can also be enhanced by the addition of external forces such as centrifugal, electrostatic, and magnetostrictive forces to improve its efficiency and accuracy. The resulting atomized sprays are characterized by higher particle size distributions, improved stability and more uniform shape. This makes them suitable for a wider range of applications than traditional sprays.In gas atomization (GA), the stream of liquid metal is disrupted by inert gases such as nitrogen, argon and helium. This method is used to manufacture a wide variety of nonferrous alloys with lower melt feed rates and a much smaller particle size distribution than rotary or fluidized bed atomization. The resulting sprays are also much less prone to drying and attrition. Worldwide annual tonnage of GA atomized powders is significantly less than that of air or water atomized metals.Another type of atomization technique is the coaxial electro hydrodynamic atomization (EHA) which generates extremely fine mist particles that are capable of carrying drugs and can be delivered through various routes [73]. Lee and his group developed a drug loaded micro/nanoparticle by using this technology where they incorporated drug with a biodegradable polymer which has a core and shell structure.
