The fluidic oscillator is a low frequency reversing chamber oscillator wherein the oscillation chamber has a reversing wall. The power nozzle is centrally located for issuing a jet of water toward the reversing wall, and a pair of liquid passages leads from the reversing chamber on each side of the power nozzle, respectively, for alternating carrying periodic pulses of water and wherein the outlet passages are smoothly extended to intersect at a common outlet to ambient and water from the passages merge to form a low-frequency swept jet of water, and the passages are dimensioned and angulated relative to each other to control a fan angle of liquid jet which is periodically swept into said common outlet to ambient water in said tub.

Abstract: In many applications where it is desired to distribute a liquid onto a surface at a very small angle of incidence, it will be necessary to reduce the momentum of the droplets to prevent ricochet off the surface. Obvious methods such as using a restrictor, reducing the operating pressure, etc. are not satisfactory due to the inadequate flow, susceptibility to clogging, etc.

The compact array of fluidic actuators of the invention may be designed to produce oscillating or pulsed jets at the exit ports with frequencies in the range of 1-22 kHz. They may be integrally manufactured along with the wing sections, flaps, tail and rudder of airplane, the inlet or exit geometries of a jet engine. When supplied with a source of fluid such as air, these arrays of actuators produce a set of fluid jets of random phase of high velocity and influence the main stream of air over the subject surface. The beneficial effects of modifying flow using the present invention include increased lift, reduced drag, improved performance and noise reduction in jet engines.

Abstract: A fluidic oscillator includes a member having an oscillation inducing chamber, at least one source of fluid under pressure, at least a pair of power nozzles connected to the at least one source of fluid under pressure for projecting at least a pair of fluid jets into the oscillation chamber, and at least one outlet from the oscillation chamber for issuing a pulsating or oscillating jet of fluid to a point of utilization or ambient. A common fluid manifold connected to said at least a pair of power nozzles. The shape of the power nozzle manifold forms one of the walls of the interaction or oscillation chamber. In some of the fluidic circuits, the length can be matched to fit existing housings. The power nozzle can have offsets which produce yaw angles in a liquid spray fan angle to the left or right depending on the direction desired. In some embodiments, the exit throat is off axis (off the central axis of the symmetry) by a small fraction to the left or right to move the leftward or rightward yaw angles in the spray. The outlet throat may be offset along the longitudinal axis by a small amount to produce a yaw angle of predetermined degree to the left or right depending on what is desired. Thus, one can construct circuits for yaw using a combination of the techniques described above which suits most applications.
