Fluid entrainment is of particular significance for the applications of synthetic jets in flow
control. We investigate the structure evolution and transient fluid entrainment by the vortex …

Vortex structures and flow scenarios of noncircular vortex rings im**ing onto walls were
studied by conducting a large eddy simulation. Three orifice aspect ratios, ARs= 3, 5, and 7 …

Vortex ring research primarily focuses on the formation from circular openings.
Consequently, the role of tunnel geometry is less understood, despite there being numerous …

The vortex dynamics of starting rectangular jets with aspect ratios of 1, 4, 8, and 10 is
investigated numerically at Reynolds number of 1000. The 45°-axis-switching for the square …

An experimental study involving Particle Image Velocimetry (PIV), and far-field microphone
measurements was carried out to investigate the mixing characteristics of a low aspect ratio …

Purpose This study aims to investigate the cross-sectional resha** in transitioning/starting
rectangular jets of aspect ratio 2 under various inlet perturbation conditions at the Reynolds …

Vortex rings form as a slug of air moves through an opening, such as the end of a shock
tube. Shock tubes have been used extensively in explosives research and have various …

Shear layers and jets have motivated many researches to use experimental, theoretical and
numerical methods for the better understanding of the fundamental physics and optimizing …

Non-axisymmetric nozzles, particularly rectangular nozzles of low aspect ratio, produce
unique flow field and acoustic characteristics that may make them superior to traditional …
