The performance of microflotation, dispersed air flotation with microbubble clouds with bubble size about 50 µm, for algae separation using fluidic oscillation for microbubble generation is investigated. This fluidic oscillator converts continuous air supply into oscillatory flow with a regular frequency to generate bubbles of the scale of the exit pore. Bubble characterization results showed t...

The interior surface of a fluidic oscillator produced by FDM (Fused Deposition Modeling)-based additive manufacturing is associated with directional pattern corresponding to the 3D printing raster angle. present research explores impact angle ? = 0 , 45, and 90° from three commercial printers versus CNC machined oscillator. characterized using an optical measurement system. performance emanated...

The control of flow separation on aerodynamic surfaces remains a fundamental goal for future air transportation. On airplane wings and surfaces, the effects include decreased lift, increased drag, enhanced unsteadiness noise, all which are detrimental to flight performance, fuel consumption, environmental emissions. Many types actuators have been designed in past counter negative separation, fr...

An axial oscillation tool is proved to be effective in solving problems associated with high friction and torque in the sliding drilling of a complex well. The fluidic axial oscillation tool, based on an output-fed bistable fluidic oscillator, is a type of axial oscillation tool which has become increasingly popular in recent years. The aim of this paper is to analyze the dynamic flow behavior ...
