Patent ID: 8870099

Claim:
A system, comprising: a spray nozzle, comprising: a first pneumatic orifice having a first inner surface extending to a first outer surface, and a second inner surface extending to a second outer surface, wherein the first pneumatic orifice is configured to expel a gas in a downstream direction, the second inner surface is substantially flat and converges with the second outer surface to form a first peak, the second outer surface has a first curved recess that is asymptotic to the downstream direction at the first peak, and the first curved recess intersects the second inner surface at the first peak; a liquid orifice disposed directly adjacent to the first outer surface and a third outer surface; and a second pneumatic orifice having a third inner surface extending to the third outer surface, and a fourth inner surface extending to a fourth outer surface, wherein the second pneumatic orifice is configured to expel the gas in the downstream direction, the fourth inner surface is substantially flat and converges with the fourth outer surface to form a second peak, the fourth outer surface has a second curved recess that is asymptotic to the downstream direction at the second peak, and the second curved recess intersects the fourth inner surface at the second peak; wherein the first and second pneumatic orifices are angled toward the liquid orifice, and wherein each curved recess is configured to establish a recirculating air flow that captures liquid droplets from the liquid orifice, and directs the liquid droplets in the downstream direction.
