Acceleration Mechanism of Auroral Particles: A Review (a. Precipitating Particles and Auroras) (Proceedings of the First Symposium on Coordinated Observations of the Ionosphere and the Magnetosphere in the Polar Regions (Part I))

Antarctic Record, 1979
A review of recent observational and theoretical results on the problem of auroral particle acceleration is given. First, evidences of the existence of field-aligned potential drops as an agent of particle acceleration are summarized.

A Study of Particle Acceleration in Blazar Jets

The Astrophysical Journal
The particle acceleration of blazar jets is crucial to high-energy astrophysics, yet the acceleration mechanism division in blazar subclasses and the underlying nature of these mechanisms remain elusive. In this work, we utilized the synchrotron spectral

Acceleration and transport of ions in turbulent current sheets: formation of non-maxwelian energy distribution [PDF]

Nonlinear Processes in Geophysics, 2009
The paper is devoted to particle acceleration in turbulent current sheet (CS). Our results show that the mechanism of CS particle interaction with electromagnetic turbulence can explain the formation of power law energy distributions.

Investigation of the Dispersion Behavior of Inertial Particles within Accelerated Domain

Journal of Applied Fluid Mechanics, 2015
This report presents a study of the dynamics dispersion behaviors of inertial particle in solid-air two-phase flow within accelerated domains using both experimental and simulation approaches. In the simulation, a threedimensional model was proposed by

Experimental Study on the Damping Effect of Multi-Unit Particle Dampers Applied to Bracket Structure

Applied Sciences, 2019
Particle damping (PD) is a passive mean of vibration control in which small metallic or ceramic particles are placed inside a cavity that attached to the primary structure at the place of high vibration amplitudes.

Parameter Optimization and Experimental Study of Particle Jet Impact Rock Breaking Nozzle

Shiyou jixie, 2018
As a core accelerating device of particles and water jet during particle jet impact rock breaking process, the nozzle’s accelerating ability determines the effect of rock breaking. On account of the straight-taper nozzle, the constant-acceleration nozzle

Anisotropic Particle Acceleration in Alfvénic Turbulence

The Astrophysical Journal
Alfvénic turbulence is an effective mechanism for particle acceleration in strongly magnetized, relativistic plasma. In this study, we investigate a scenario where turbulent plasma is influenced by a strong guide magnetic field, resulting in highly ...
