Modeling the gas and liquid flow in the channels of the microplasmatron that is a plasma unit for applying fine coatings

Abstract

This article describes a mathematical model of the flow of working gas and coolant in the channels of the microplasmatron of an industrial unit for the plasma application of fine coatings to confirm the performance of the installation. The unit is designed for applying protective coatings that make it possible to strengthen the surface of a certain part, which subsequently makes it possible to increase its service life. For convenience, the study is carried out in the universal Ansys Fluent software module, which has a wide range of capabilities for modeling the flow of liquids and gases, allowing one to identify the dominant physical phenomena occurring in the installation. As a result, calculation results were obtained in the form of distributions of temperatures, velocities and pressures within the volume of the working area of gas and liquid, and the operability of the installation element was confirmed.
