Basics of nozzle technology

Nozzles are used in a wide variety of applications. Therefore nozzles have to meet a lot of different requirements. One of those requirements is applying the right spray pattern for a specific application.

The process of generating spray patterns

A nozzles spray-characteristics are basically influenced by the following factors:

  • Geometric design of the nozzle outlet
  • Medium properties (specifc gravity, viscosity)
  • Internal geometry (swirl part, swirl chamber)
  • Supply of the medium (axial- or tangential flow)
