Flow Control of Leading Edge Separation on Airfoil Using Dbd Plasma Actuator

Highly efficient electron vortex beams generated by nanofabricated phase holograms

Kelvin-wave turbulence generated by vortex reconnections

Reconnections of quantum vortex filaments create sharp bends which degenerate into propagating Kelvin waves. These waves cascade their energy down-scale and their waveaction up-scale via weakly nonlinear interactions, and this is the main mechanism of turbulence at the scales less than the inter-vortex distance. In case of an idealised forcing concentrated around a single scale k0, the turbulen...

Phase-averaged scanning stereoscopic PIV measurement for classification of vortex regime of synthetic jet in cross flow

A synthetic jet is one of flow control devices that can topologically disturb surrounding flow field by adding periodic injection and suction of surrounding fluid using an oscillating membrane through an orifice. This device can be applied to the downsized fluid machinery without a net mass injection of fluid for the simplified structure. In this study, the phase-averaged three-dimensional flow...
