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.

Increasing stagnation pressure and thermonuclear performance of inertial confinement fusion capsules by the introduction of a high-Z dopant

Physics of Plasmas, 2018
Inertial confinement fusion requires the inertia of the imploding mass to provide the necessary confinement such that the core reaches adequate high density, temperature, and pressure. Experiments utilize low-Z capsules filled with hydrogenic fuel, which

Measurements of the stagnation pressure in the center of a cavitating jet [PDF]

, 2011
The stagnation pressure at a certain distance from the nozzle is important for the erosion/ cutting capacity of a submerged jet in dredging. The decay of the stagnation pressure with jet distance is well known in the case of non-cavitating jets.

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).

Identifying the processes and characterizing the pressure zone of water jet impacting on solid surface

Advances in Mechanical Engineering, 2022
The difficulty in understanding the flow characteristics of water jets impacting on solid surfaces made the water jet technology requiring further investigations. The Arbitrary Lagrange-Euler (ALE) method is used to develop a numerical model of the water
