2. Spray nozzle - Wikipedia

   en.wikipedia.org/wiki/Spray_nozzle

   New York, 1890-1930. A spray nozzle or atomizer is a device that facilitates the dispersion of a liquid by the formation of a spray. The production of a spray requires the fragmentation of liquid structures, such as liquid sheets or ligaments, into droplets, often by using kinetic energy to overcome the cost of creating additional surface area.

3. Spray (liquid drop) - Wikipedia

   en.wikipedia.org/wiki/Spray_(liquid_drop)

   Spray (liquid drop) A spray is a dynamic collection of drops dispersed in a gas. [1] The process of forming a spray is known as atomization. A spray nozzle is the device used to generate a spray. The two main uses of sprays are to distribute material over a cross-section and to generate liquid surface area.

4. Spray drying - Wikipedia

   en.wikipedia.org/wiki/Spray_drying

   There are two main types of nozzles: high pressure single fluid nozzle (50 to 300 bars) and two-fluid nozzles: one fluid is the liquid to dry and the second is compressed gas (generally air at 1 to 7 bars). Spray dryers can dry a product very quickly compared to other methods of drying.

5. Nozzle - Wikipedia

   en.wikipedia.org/wiki/Nozzle

   A nozzle is often a pipe or tube of varying cross sectional area, and it can be used to direct or modify the flow of a fluid (liquid or gas). Nozzles are frequently used to control the rate of flow, speed, direction, mass, shape, and/or the pressure of the stream that emerges from them. In a nozzle, the velocity of fluid increases at the ...

6. Ultrasonic nozzle - Wikipedia

   en.wikipedia.org/wiki/Ultrasonic_Nozzle

   Ultrasonic nozzle. Ultrasonic nozzles are a type of spray nozzle that use high frequency vibrations produced by piezoelectric transducers acting upon the nozzle tip that create capillary waves in a liquid film. Once the amplitude of the capillary waves reaches a critical height (due to the power level supplied by the generator), they become too ...

7. Spray painting - Wikipedia

   en.wikipedia.org/wiki/Spray_painting

   Spray painting. Spray painting is a painting technique in which a device sprays coating material (paint, ink, varnish, etc.) through the air onto a surface. The most common types employ compressed gas—usually air —to atomize and direct the paint particles. Spray guns evolved from airbrushes, and the two are usually distinguished by their ...
