Hollow Cone Spray Pattern

A hollow cone nozzle sprays fluids in a ring-like pattern around a given radius. Hollow cone nozzles produce a good interface between air and the surface of the droplets.

There are 2 types of hollow cone nozzle designs.

Image

Axial

  • Spray exits on the same axis it enters
  • Internal channels or vanes causes the liquid to spin, and the centrifugal force exerted upon the geometry of the exit creates the spray pattern
  • Spray is concentrated on outer edges
  • Smaller droplets than full cone
Image

Tangential (Right Angle)

  • Spray exits 90° from the entry axis
  • Internal geometry creates the spray pattern by the liquid swirling around the body cavity before exiting the orifice
  • Spray is concentrated on outer edges
  • Smaller droplets than full cone
Examples of Why You Would Choose This Spray Pattern Over Others
  • In gas cooling applications, a small droplet size is desired,and a full cone nozzle may not be small enough.

  • Tangential hollow cone nozzles are perfect for low clearances when a pattern needs to be directed 90° from the inlet.
