Abstract: A fire suppression nozzle can include a first fluid channel configured to be in fluid communication with a first fluid having a first flow velocity and a second fluid channel configured to be in fluid communication with a second fluid having a second flow velocity. A mixer can be disposed between the first fluid channel and the second fluid channel such that the mixer is configured to induce streamwise vorticity in at least the first fluid exiting first fluid channel to cause mixing of the first fluid and the second fluid to reduce a flow speed of a mixture of the first fluid and the second fluid.

Abstract: A nozzle assembly for a fire suppression system is disclosed. In some embodiments, the nozzle assembly comprises a body having an inlet end for receiving a flow of fire extinguishing agent from the fire suppression system at an inlet pressure; a nozzle portion extending from the body and having an interior cavity; and a conical central body located in the interior cavity, extending upstream from a base of the nozzle portion, wherein a plurality of exit orifices are formed in an outer wall of the nozzle portion, in communication with the interior cavity, for vectoring the flow of fire extinguishing agent exiting therefrom.
