Modelling of chemical reactions in plasma

The paper is devoted to theoretical investigation of interaction of pulsed high current electron beam with gas substance. As a result of the interaction the formation of chemical active plasma can be observed. One of the key parameter for theoretical analyze of the process is the electron distribution function. Within the framework of the Boltzmann approach we obtained the dynamical equation for electron distribution function depending on the electron energy, coordinate and time

The impact of a shock-compressed layer on the mass transfer of target material during processing compression plasma flows

The paper describes the results of experimental and numerical research of the thickness of the molten bath and the surface erosion of a substance under the influence of compression plasma flows. It has been demonstrated that the formation of the shock-compressed layer affects the melted depth and the mass erosion from the surface of the treated target

Среди основных механизмов массопереноса в работе рассматривается неустойчивость Кельвина–Гельмгольца (НКГ). Показано, что развитие НКГ и другие возмущения профиля поверхности создают условия для развития сдвиговой термокапиллярной неустойчивости, а толщина области перемешивания может достигать нескольких мкм, она ограничена толщиной расплава. A Mass-transfer process is an important factor in development of new properties of materials. The article considers Kelvin–Helmholtz instability apart from basic mechanisms of mass-transfer. It is shown that development of Kelvin–Helmholtz instability and blooming create conditions for shift thermocapillary instability development, a depth of a convective zone may reach several microns, it is limited to melt depth
