In this video, I explain the science behind the plasma vortex from my last two videos works. In short, there is a Lorentz force acting on the arc. The current flowing through the arc is acted on...

2019年6月22日 · In this article, we describe recent progress on vortex formation in low temperature and partially ionized laboratory plasmas. An emphasis is paid on the effect of neutral flow coexistent with charged particles (ions). It is shown that there is a new route to vortex, which is determined by interplay between plasma and neutral particles.

1994年12月1日 · In particular the dynamics of monopolar and dipolar vortices in a plasma with nonuniform density and in a rotating fluid with varying Coriolis force is described. The role of vortical structures...

2024年2月28日 · Notably, the Magnetic Vortex Acceleration mechanism exhibits high efficiency in coupling the laser energy into the plasma in the optically shaped targets, resulting to collimated proton beams of...

The plasma vortex generator was oriented along the primary flow direction to produce a body force in the spanwise direction. This created a spanwise-directed wall jet which interacted with the oncoming boundary layer to form a coherent streamwise vortex.

2022年5月15日 · We introduce two theorems and two corollaries, applicable to any non-collisional plasma system, that relate the vorticity to electromagnetic variables. We also introduce a toy vortex model for the wakes of non-magnetised planetary bodies.

The streamwise vortices generated by dielectric-barrier-discharge plasma actuators in the laminar boundary layer were investigated using particle image velocimetry to understand the vortex-formation mechanisms. The plasma vortex generator was oriented along the primary flow direction to produce a body force in the spanwise direction.

2024年10月9日 · Due to the nonlinear interaction between VEMW and plasma, the plasma also presents a vortex state. This propagation model of VEMW can provide some theoretical support for the application of VEMW in ionospheric heating and shortwave communication.

2023年1月1日 · Using rf CO 2 rf plasma, we obtain a special dusty plasma system with two vortices that can be seen as a structure with both crystalline and liquid phases. The collective displacement of 7 mm on a horizontal axis is achieved by triggering a neutral gas pushing force.

Vortices excited in magnetized plasmas are described in this review article. An emphasis is paid on vortex formation in partially ionized plasmas, in which ion and neutral particles coexist.
