Abstract: A mathematical model is presented that describes the relative motion and heart exchange of a fine spherical particle of variable diameter in a heterogeneous carrier medium under conditions of nonisothermal free convection of the inhomogeneous heterogeneous medium in a plasmatron reactor. The model is based on jointly solving the Navier–Stokes equations, continuity equations, and energy conservation equations (written in terms of the Euler variables) for the carrying fluid and the equation of motion (in Lagrange variables) and nonlinear heat conduction equation for the particle. Based on this model, it is possible to calculate the hydrodynamics and heat exchange of the inhomogeneous heterogeneous dispersed medium in the plasmatron reactor, the dynamics of relative motion, and heat exchange of dispersed particles in the continuous carrier medium with allowance for phase transformations under conditions of high-temperature processing of dispersed materials.
