Abstract

A numerical analysis is conducted on heat transfer and fluid flow of a high-temperature jet including particles in plasma spraying, which is utilized to produce heatresistant, anticorrosion and abrasion-resistant coatings. Finite heat conduction analysis is adopted to consider the internal temperature distribution in a particle and further, the forces induced by the relative motion are added to the Stokes drag term in the equation of particle motion. The comparison between Lagrangian and Eulerian approaches to the evolution of velocity and temperature of alumina particles is presented. The equation of particle motion is calculated using the 4th order Runge-Kutta method, as is the residence time of particles in each calculation cell of the flow field using the bisectional method which was developed by us. Particles of three different materials (Al2O3, Ni, W) are considered and the coupling between two phases is examined on the basis of the momentum and energy exchange.
