Numerical Simulation of Plasma Spraying Performance Index

Abstract

In recent years, there has been an increasing interest in plasma jet numerical simulation. Speed and temperature propagation in axial and radial direction in plasma jet significantly influences on speed and temperature of sprayed material and therefore on coating quality. However, there are few studies concerning plasma jet numerical simulation in modern software systems and they describe a specific problem. It is a wellknown fact that using simple structural components such as plasmatron heads for plasma thermal spraying allows us to increase the quality of zirconium oxide coatings by increasing the speed of spraying particles and decreasing their spread value and allows to increase economic efficiency of the process by increasing the operation factor of spraying material. However, scientists have not studied well the influence of the plasmatron head, which looks like a cone element, and the simulation of a high temperature flow along the channel is not mentioned in publications. Therefore, it is necessary to research the flow of a high temperature current along the channel of the head.

“…Therefore, the most important task when creating a high-voltage storage battery is to reduce the cost, ensure the required safety, increase the resource and extend the life cycle of the high-voltage battery. The optimal design of the storage cell, high-voltage battery, and high-voltage battery management system should be developed [1][2][3][4]. To create an effective control system for the processes occurring in the cells of a high-voltage battery, a mathematical simulation model is required to be created which studies physical processes and selects the optimal configuration and settings of the control system.…”
