Multiscale modeling of powder materials processing for additive manufacturing in inductively coupled plasma

Abstract

This article analyzes the approaches to macro- and mesoscale computational modeling of the dynamics of metal powder particles motion in the condensation chamber of a plasma reactor, spheroidization, coagulation, and phase transitions in particles. The features of different regimes of vaporization and condensation were described. The influence of phenomena such as Brownian motion and thermophoresis on the process was explored. The parameters of the process at which the formation of core-shell particles occurs were determined. The model can be used to optimize and select the effective regimes for the processing and synthesis of powder materials in inductively coupled plasma.
