Fluidic oscillators are based on the bi-stable states of a jet (or a pair of jets) of fluid inside a specially designed flow chamber. These produce sweeping or pulsing jets of high exit velocity (similar to sonic exit velocities) extending the control authority achievable to high subsonic flo...
to, and flow along, a wall. In bistable fluidic devices the supply jet can be made to switch from one outlet to the other by the application of a relatively small control pressure. In astable fluidic oscillators the supply jet can be made to switch from one outlet to the other ...
In thermofluidic oscillators (e.g. fluidic oscillators of the heat engine or heat pump classes), a second, thermal, feedback phase angle also exists. This thermal phase angle arises due to the time delay between the temperature at which heat is exchanged and the rate of flow of entropy bet...
Development of fluidic oscillators as flow control actuators This work is comprised of two key accomplishments: the study and design of fluidic oscillators for flow control applications, and the development and application of porous pressure-sensitive paint (PSP) for unsteady flowfields. PSP devel......
摘要: A fluidic flowmeter is located downstream of a valve. A wire gauze or net having small meshes is located on the upstream side of a nozzle forming the inlet to the fluidic element to stabilize flow. 展开 收藏 引用 批量引用 报错 分享 ...
Drag Reduction on the 25-deg Ahmed Model Using Fluidic Oscillators Transportation of goods and people involves moving Metka,Matthew,Gregory,... - 《Journal of Fluids Engineering Transactions of the Asme》 被引量: 4发表: 2015年 Cluster-based control for net drag reduction of the fluidic pinball ...
For each flap angle, the effects of the pitch angle of the oscillators on the aerodynamic performance were evaluated in a range of 60° to the negative value of the corresponding flap angle. It was found in this work that the oscillator jets parallel to the flap showed the best performance...
The subject invention relates to oscillators, and in particular to a fluidic oscillator whose operating frequency is related to fluidic binary signals applied to the oscillator. One possible use for an oscillator according to the invention is in connection with dust collecting apparatus. Dust collecting...
The present invention incorporates fluidic oscillators adaptable for submerged operation, e.g. for spa use, which can be caused to sweep or not sweep a jet of water with simple manual adjustment from the front of the device. In addition, the frequency of oscillation or sweeping of the water ...
