摘要：

The paper presents a study of the drag coefficient of a spherical Al2O3 particle in a thermal plasma flow. An unsteady model of the interaction of a fine particle in a rectangular channel with a laminar compressible non-isothermal flow has been developed. An analysis of the influence of boundary conditions on the simulation results is performed. Based on the results of a parametric study, the functional dependences of the drag coefficient and the Nusselt number necessary for simulation of plasma coating technology are determined. © 2024 ORION Research-and-Production Association.
