This paper concerns momentum and heat transfer to a nonevaporating oxidized steel spherical particle (diameter 6.5 mm − 8 mm) levitated at high Reynolds number in argon turbulent plasma jet flowing into cold air. The rapid rotation of the particle in the plasma flow ensures the stability of the levitation phenomenon over a wide range of plasma torch parameters. We use a dimensional analysis to describe the momentum transfer and the equilibrium levitation height data. The convective heat transfer coefficient was further estimated from gas and particle equilibrium temperature at the front stagnation point or from the analysis of the transient temperature signal for a particle abruptly immersed and levitated in the plasma jet. Particle rotation is shown to determine the heat transfer rate in a nonuniform plasma flow.
