In 1756, Leidenfrost 1 observed that water drops skittered on a sufficiently hot skillet, owing
to levitation by an evaporative vapour film. Such films are stable only when the hot surface is …

We demonstrate and quantify a highly effective drag reduction technique that exploits the
Leidenfrost effect to create a continuous and robust lubricating vapor layer on the surface of a …

We present new observations from an experimental investigation of the classical problem of
the crown splash and sealing phenomena observed during the impact of spheres onto …

Micro-scale flow distribution in spacer-filled flow channels of spiral-wound membrane modules
was determined with a particle image velocimetry system (PIV), aiming to elucidate the …

An experimental study to examine the hydrodynamic performance and start-up phase of
liquid jets for needle-free injection was performed. With the use of high-speed videography at …

We provide an experimental demonstration that a novel macroscopic, dynamic continuous air
layer or plastron can be sustained indefinitely on textured superhydrophobic surfaces in air…

This paper reports a detailed characterization of laser-induced micro-jets, including ex vivo
experiments using skin as a target substrate to check the feasibility in terms of needle-free jet …

We present results from a combined numerical and experimental investigation into the
squeeze flow induced when a solid sphere impacts onto a thin, ultra-viscous film of non-…

An experimental study was performed to assess the hydrodynamics of liquid jets used for
needle-free injection, where the typical orifice diameter is ~155 μm and velocity is in range of ~ …

In this study, needle-free jet injection dynamics were studied using homogeneous gelatin as
model substrates. Whilst keeping nozzle properties such as orifice diameter ( d o ) and …
