Calculation of portable properties of some real gas mixtures at high temperatures

Abstract

A method for calculating the power parameters of a potential of the Lennard-Jones type for a number of individual gases, which can be products released during the ignition and combustion of a gas-vapor discharge with a liquid electrode, is presented. The information obtained makes it possible to calculate the viscosity and diffusion coefficients of individual gases and gas mixtures, which will make it possible to solve a range of problems when modeling processes in the processing technology of various materials (substances) by vapor-gas discharge plasma with a liquid electrode.

Mathematical optimization of technology for reducing the roughness of metal surfaces

“…The processes that occur at the solid electrode-electrolyte interface and in the discharge gap during surface treatment with a vapor-gas discharge are a set of various interrelated phenomena, such as physical, chemical and electrochemical ones. The main physicochemical phenomena that determine the process of processing metal surfaces are the electric field, modes of heat and mass transfer between the processed metal surface and the liquid medium (electrolyte) [1,[4][5][6][7][8][9][10]. During the experiment, it is necessary to control the parameters of the vapor-gas discharge (discharge voltage, current in the discharge gap, electrolyte temperature, etc.…”

“…Due to the large number of physical parameters that significantly affect the processing of a part, difficulties arise in planning and conducting experiments in order to optimize the technology for processing metal surfaces. Therefore, the implementation of experiments takes a lot of time and resources, therefore, more monetary costs are required [2][3][4]. This problem can be solved using mathematical modeling, which allows you to explore various processes and phenomena at no additional cost.…”
