Particle image velocimetry (PIV) has become the chief experimental technique for velocity
field measurements in fluid flows. The technique yields quantitative visualizations of the …

Secondary atomization of a liquid droplet can be achieved by subjecting it to a high-speed
gas stream. This is referred as the aerodynamic breakup, and is encountered in various …

Human-generated droplets constitute the main route for the transmission of coronavirus.
However, the details of such transmission in enclosed environments are yet to be …

The deformation and breakup of droplets in airflows is important in spray and atomisation
processes, but the shear effect in non-uniform airflow is rarely reported. In this study, the …

The aim of this paper is to characterize large-scale instabilities during the primary breakup
process in liquid centered coaxial air-water jets. The interest here is to investigate the role of …

Active drag reduction of an Ahmed body with a slant angle of, based on the square root of
the model cross-sectional area. Four individual actuations, produced by steady blowing, are …

This paper intends to investigate the influence of unsteadiness in the liquid jet disintegration
process on downstream fluctuations of spray characteristics in a coaxial twin-fluid injector …

The aim of this paper is to experimentally characterize the liquid jet breakup unsteadiness in
a coaxial air-blast atomizer. The current research focuses on the measurement of the …

The interaction of a droplet with a swirling airstream is investigated experimentally using
shadowgraphy and particle image velocimetry techniques. In swirl flow, the droplet …

We investigate the morphology and size distribution of satellite droplets resulting from the
interaction of a freely falling water droplet with a swirling airstream of different strengths by …
