Spray Nozzle 05
Spray Nozzle 05 : (4) Pressure-Swirl Single-Fluid Spray Nozzle: Pressure-swirl spray nozzles are high-performance (small drop size) devices with one configuration shown. The stationary core induces a rotary fluid motion which causes the swirling of the fluid in the swirl chamber. A film is discharged from the perimeter of the outlet orifice producing a characteristic hollow cone spray pattern. Air or other surrounding gas is drawn inside the swirl chamber to form an air core within the swirling liquid. Many configurations of fluid inlets are used to produce this hollow cone pattern depending on the nozzle capacity and materials of construction. The uses of this nozzle include evaporative cooling and spray drying. A spill-return pressure-swirl single-fluid nozzle is one variety of pressure swirl nozzle includes a controlled return of fluid from the swirl chamber to the feed system. This allows the nozzle pressure drop to remain high while allowing a wide range of operating rates
