Discrete vortex rings impinging on concave hemispherical cavities were explored
experimentally. Planar laser-induced fluorescence, two-dimensional particle image …

This work presents a volumetric calibration method for single-camera light-field particle
image velocimetry (light-field PIV or LF-PIV). The proposed technique makes use of the …

Experimental investigations were conducted on a single vortex ring impinging on a concave
hemi-cylindrical shell with D m/D e= 2 at different Reynolds numbers. Vortex rings with five …

A study on is distinctively different from those at larger included angles. Vortex-core
trajectories are compared to those for inclined-wall collisions, and secondary vortex-ring …

For the first time, an experiment has been conducted to investigate synthetic jet laminar
vortex rings impinging onto porous walls with different geometries by time-resolved particle …

Vortical structures and behaviour associated with vortex-ring collisions upon round cylinders
with different cylinder-to-vortex-ring diameter ratios were studied using laser-induced …

A numerical investigation was conducted on hemisphere hypothesizes that the recurring
tertiary vortex ring formations cease only when the primary vortex ring slows down …

Light-field particle image velocimetry (LF-PIV) was recently introduced to measure three-
dimensional, three-component velocity field with just a single light-field camera. One of the …

A large-eddy simulation based numerical study was conducted on head-on collisions
between vortex-rings and round cylinders. The vortex-ring Reynolds number was Re= 4000 …

This work presents a volumetric calibration method for Scheimpflug plenoptic camera in
particle image velocimetry. To establish a prerequisite foundation for the Scheimpflug light …
