Numerical simulation of motion of dust particles in an accelerator path

Abstract

The model of micron charged particles motion in an electrostatic accelerator path is presented. This article describes software that provides formation of a particle packet with given statistical characteristics and the results of modeling, obtained by the supercomputer Sergey Korolev. Performance of software implementation for the supercomputer, parallel implementation for PC and implementation for GPU is being considered. Comparison with experimental data was carried out; convergence of full-scale and numerical experiments was shown.

Dynamics of dust particles with virions in gas cloud

“…The problem of the movement of viruses in gases is one of the fundamental problems of modern mechanics, relevant for gas dynamics, climatology, etc., including for medicine, A large number of works are devoted to modeling the movement of solid particles, including micron particles. [5][6][7][8] The main methods used by the authors in the articles are analytical and numerical [5,9,10]. Both the methods themselves and the methods of their application are being improved.…”

Simulation of the control system of the electrodynamic accelerator of dust particles

“…We developed and constructed an accelerator [3,[6][7][8] of high speed particles, which allows to simulate impacts of micrometeorites with a size of 1 ÷ 10 um and speeds of 1-15 km / s with materials of spacecraft structures under laboratory conditions. Figure 1 shows a block diagram of a linear accelerator for simulation of micrometeorites, the path of which consists of an injector, linear electrostatic accelerator (LESA), linear electrodynamic accelerator (LEDA), three measuring lines and an experiment chamber.…”
