Simulation processing of disperse materials process in a continuous-flow plasma reactor

Abstract

The paper presents a numerical simulation of the propagation of the direct-flow temperature plasma reactor at a different size of the heat source, which is solved by the Navier - Stokes and temperature equations, based on the splitting method by physical parameters that are approximated by finite difference method. In the numerical solution of the equation system can be divided into four stages. The first stage is that the transfer of momentum carried out only by convection and diffusion. The intermediate velocity field is solved by fractional steps method. At the second stage, based on the found intermediate velocity field is a field of pressure. The Poisson equation for pressure field is solved by the Fourier method. In a third step it is assumed that the transfer is carried out only by the pressure gradient. The fourth step of the equation is solved for the temperature equation as well as the motion equations by fractional steps method. The algorithm is parallelized on high-performance systems. With this numerical algorithm was obtained numerical results of temperature distribution in a continuous-flow plasma reactor. Numerical modeling allows us to give a more precise description of the processes that have been identified or studied theoretically by laboratory methods, and can reveal new physical phenomena processes that are not yet available, seen in experimental studies.
