Journal ArticleDOI
Liquid-jet impact on liquid and solid surfaces
TL;DR: In this article, the authors investigated the mechanisms of the liquid-jet impact on liquid and solid surfaces associated with cavitation damage and rain erosion, using an image-converter high-speed camera.
Journal ArticleDOI
Diffraction and re-initiation of detonations behind a backward-facing step
TL;DR: In this article, the authors used high-speed schlieren photography and soot-track records as well as pressure measurements on the sidewall to observe the diffraction phenomena of gaseous detonation waves behind a backward-facing step in a tube.
Journal ArticleDOI
High-speed photography and stress gauge studies of jet impact upon surfaces
TL;DR: In this article, the mechanisms of damage to brittle materials by liquid-jet impact as seen in cavitation or simulated rain erosion were investigated using a liquid jet of 3 mm in diameter.
Journal ArticleDOI
Mechanism of deflagration-to-detonation transitions above repeated obstacles
TL;DR: In this paper, a stoichiometric gas of oxygen and hydrogen (oxy-hydrogen) is ignited in a tube, repeated obstacles are installed, and the DDT behaviors are visualized using a high speed video camera.
Journal ArticleDOI
A numerical simulation of reflection processes of a detonation wave on a wedge
TL;DR: In this paper, a two dimensional numerical simulation has been performed to study reflection processes of detonation waves on a wedge, where the numerical scheme adopted is the flux corrected transport scheme and a two-step chemical reaction is assumed for a stoichiometric oxyhydrogen mixture diluted with argon.
