Claim 0:
1. A fluidic oscillator comprising:
a first portion, a second portion, and a middle portion coupled between the first portion and the second portion, the middle portion have a first end and a second end opposite the first end, the middle portion comprising:
an interaction chamber,
a fluid supply inlet for introducing a fluid stream into the interaction chamber,
a single outlet nozzle disposed at the second end of the middle portion and downstream of the fluid supply inlet, wherein a fluid stream exits the interaction chamber through the single outlet nozzle such that the fluid stream oscillates to define a sweeping angle of the fluid stream exiting the single outlet nozzle, the single outlet nozzle having a first end, a second end, and a narrowest portion disposed between the first end of the single outlet nozzle and the second end of the single outlet nozzle, wherein the narrowest portion of the single outlet nozzle has a smallest inner area in a plane parallel to the second end of the middle portion, and the first end of the single outlet nozzle being closer than the second end of the single outlet nozzle to the fluid supply inlet, and
a first control port and a second control port, the first control port for introducing a first control fluid into the fluidic oscillator in a first flow direction and the second control port for introducing a second control fluid into the fluidic oscillator in a second flow direction, the first control port being defined by the first portion and the second control port being defined by the second portion, the first and second control ports being defined by, and in fluid communication with, the single outlet nozzle, and wherein the first flow direction differs from the second flow direction,
wherein the first control fluid and the second control fluid introduced into the fluidic oscillator are controllable to adjust the sweeping angle of the fluid stream exiting the single outlet nozzle for a given flow rate.
