Classification: CPC A  B | IPC A  B

Claim 4:
5. A fire suppression nozzle, comprising:
a first fluid channel configured to be in fluid communication with a first fluid having a first flow velocity;, a second fluid channel configured to be in fluid communication with a second fluid having a second flow velocity; and
a mixer 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 the 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, wherein streamwise vorticity includes rotational flow, wherein the first fluid channel is defined by a nozzle body, wherein the mixer is defined by the nozzle body or attached to the nozzle body, wherein the second fluid channel is defined at least partially by an upper shroud disposed around the nozzle body, the second fluid channel defined at least partially between the upper shroud and the nozzle body, wherein the upper shroud is attached to the nozzle body by one or more ribs, wherein the second fluid is air and the upper shroud is open to the atmosphere to allow air to be drawn in by the flow entrainment effect from the first fluid effusing from the first fluid channel to mix air with the first fluid.
