摘要： A fluidic device which produces fluid pulses having a selected pulse repetition frequency, pulse duration, pulse peak pressure and pulse peak flow rate includes first, second and third fluid flow controlling channels or lumens which converge in a junction, defining a “Y” configuration having a base leg and right and left diverging arms. The first leg portion has a fluid input and terminates downstream at the Y junction of the base and the two diverging arms. The first leg has converging walls which reduce the cross sectional area of the flow to thereby increase the fluid velocity to make a fluid jet. The second or right leg, begins at the Y junction and terminates distally in an enclosed, fluid-tight container having a selected blind volume. The third, or left leg, begins at the Y junction and terminates distally in a fluid outlet passage having a selected cross-sectional area.

摘要： A full coverage fluidic oscillator (2) includes a fluidic circuit member preferably having an oscillation inducing internal chamber, at least one inlet (8) or source of fluid under pressure, at least a pair of output nozzles (14, 16) connected to the source of fluid for projecting at least first and second impinging fluid jets into free space, where the first and second impinging jets collide or impinge upon one another at a selected jet angle to generate a substantially omni-directional sheet jet having selected thickness. The first and second jets are aimed at a pre-selected intersection point in free space where impingement is to occur. The sheet jet's thickness Δy is determined by the time-varying path or oscillation of each of the first and second impinging jets. The first and second impinging jets can be made to oscillate or pulsate by use of vortex generating amplifier structures (68, 70, 72, 149) within the internal chamber's fluid flow paths.

摘要： A fluidic oscillator suitable for use at colder temperatures for generating an exhaust flow in the form of an oscillating spray of fluid droplets has an inlet for pressurized fluid, a pair of power nozzles configured to accelerate the movement of the pressurized fluid, a fluid pathway that connects and allows for the flow of pressurized fluid between its inlet and the power nozzles, an interaction chamber which is attached to the nozzles and receives the flow from the nozzles, a fluid outlet from which the spray exhausts from the interaction chamber, and a means for increasing the instability of the flow from the power nozzles, with this means being situated in a location chosen from the group consisting of a location within the fluid pathway or proximate the power nozzles. In a first preferred embodiment, the flow instability generating means comprises a protrusion that extends inward from each side of the fluid pathway so as to cause a flow separation region downstream of the protrusions. In a second preferred embodiment, the flow instability generating means comprises a step in the height elevation of the floor of the power nozzles with respect to that of the interaction chamber.
