New approach to an underwater discharge simulation using elliptic coordinates

Autor: Vitaliy Stelmashuk

Publikováno v: AIP Advances, Vol 10, Iss 1, Pp 015102-015102-7 (2020)

In this study, a system of two equations is developed that allows the time evolution of the underwater spark channel to be calculated numerically from a given power input. The proposed mathematical model utilizes the elliptical coordinates. This appr

The pressure in an underwater discharge channel is the main parameter that influences all its applications. In this study, we investigate a relatively large gap with a plane-to-plane electrode geometry that uses the assistance of an injected gas bubb

Publikováno v: Journal of Applied Physics. 133:033301

The results of experimental research on the acoustic and electrical characteristics of underwater spark discharges facilitated by a preliminary discharge are presented. The latter was produced through the application of a short duration high-voltage

Optical Emission Spectroscopy of Underwater Spark Generated by Pulse High-Voltage Discharge with Gas Bubble Assistant

Autor: Vitaliy Stelmashuk, Vaclav Prukner, Karel Kolacek, Andrii Tuholukov, Petr Hoffer, Jaroslav Straus, Oleksandr Frolov, Vit Jirasek

Publikováno v: Processes; Volume 10; Issue 8; Pages: 1474

This paper is aimed at the investigation of the acoustic and spectral characteristics of underwater electric sparks generated between two plate electrodes, using synchronized gas bubble injection. There are two purposes served by discharge initiation
