Micrometer-sized droplets from liquid helium jets at low stagnation pressures [PDF]
Physics of Fluids, 2022 Droplets and droplet beams produced from the breakup of micrometer-sized liquid helium jets in vacuum were studied in this work, advancing into previously unexplored regimes of low stagnation pressures. Using a 5 μm orifice, the droplet beam shows surprisingly diverse characteristics at increasing nozzle pressures from 0.6 to 100 bar: a well-collimated

Pressure Anomalies Beneath Solitary Waves with Constant Vorticity
Eng, 2023 While some studies have investigated the particle trajectories and stagnation points beneath solitary waves with constant vorticity, little is known about the pressure beneath such waves.

Conceptualisation of a novel electromechanical system for small-volume needle-free jet injection
Engineering Applications of Computational Fluid Mechanics, 2023 Needle-free jet injectors are minimally invasive drug delivery systems that utilise high-velocity microjets (∼100 m/s) created by pressurising the liquid drug through a micronozzle (50–300 µm in diameter).

Impinging jets array: an experimental investigation and numerical modeling [PDF]
E3S Web of Conferences, 2019 This paper reports on the measurements of wall shear stress and static pressure along a smooth static wall upon which jet impingement occurs. The effect of a single circular jet, respectively an array of jets is studied using a high speed/resolution ...
