Abstract
A spray nozzle comprising a housing including a primary passage defining a primary axis, a series of secondary passages configured to provide swirl to a fluid passing therethrough circumferentially positioned around the housing, a series of standoffs circumferentially spread around an outer surface of the housing and located downstream along the primary axis of the series of swirling passages, wherein each of the swirling passages corresponds to a respective standoff of the series of standoffs, in order to control the swirl of the fluid.

A spray nozzle comprising:
- a housing including a primary passage defining a primary axis;
- a series of secondary passages configured to provide swirl to a fluid passing therethrough, circumferentially positioned around the housing;
- and
- a series of standoffs circumferentially spread around an outer surface of the housing and located downstream along the primary axis of the series of swirling passages, wherein each of the swirling passages corresponds to a respective standoff of the series of standoffs, in order to control the swirl of the fluid, wherein each of the standoffs is circular.
A spray nozzle comprising:
- a housing including a primary passage defining a primary axis;
- a series of secondary passages configured to provide swirl to a fluid passing therethrough, circumferentially positioned around the housing;
- and
- a series of standoffs circumferentially spread around an outer surface of the housing and located downstream along the primary axis of the series of swirling passages, wherein each of the swirling passages corresponds to a respective standoff of the series of standoffs, in order to control the swirl of the fluid, wherein a distance between each of the standoffs is greater than a diameter of each of the standoffs.
A method of spraying a fluid comprising the steps of:
- feeding a fluid stream through a primary passage of a nozzle along a primary axis;
- producing a swirling fluid stream through a series of secondary passages along a secondary axis, at a non-parallel angle to the primary axis;
- and
- reducing the swirl of the fluid by impinging the fluid against a series of standoffs downstream of the secondary passages, wherein each of the standoffs is circular, wherein a distance between each of the standoffs is greater than a diameter of each of the standoffs.
