Diffusion Control of Doublet Flow Consisting of Injection and Suction Flow.

Turbulent characteristics in flow subjected to bed suction and jet injection as a pier-scour countermeasure

The effect of a combined system of the bed suction and jet injection as a pier-scour countermeasure on the turbulent flow field is studied in a laboratory flume using an Acoustic Doppler Velocimeter (ADV). The three components of the velocities in the vertical symmetry plane in the equilibrium scour hole in front and rear of the pier under 3-jet injections and bed suction rate Qs/Q0 = 2%located...

Analysis of Transient Flow in the Case of Secondary Injection for Transient Vector Control (RESEARCH NOTE)

The purpose of this paper is to analyze the flow field structure in transient state and performance of secondary injection system for thrust vectoring in divergent section of a two-dimensional nozzle. Secondary injection for thrust vectoring in a two-dimensional nozzle is studied by solving three-dimensional Reynolds-averaged equations by means of fluent solver. Spalart-allmaras model was used ...

On-demand Control of Microfluidic Flow via Solenoid Microvalve Suction

A simple, low-cost and on-demand microfluidic controlling platform was developed based on a capillary-tuned solenoid microvalve suction effect without any outer pressure source. The suction effect was employed as a stable driving force for manipulating micro-fluid by connecting a piece of capillary tubing between the microvalve and the chip. The suction volume could be controlled from microlite...
