<p>Numerical modeling of atmospheric pressure current-carrying argon plasma containing a single spherical metal particle was performed. The plasma is described in the hydrodynamic approach with account for its thermal and ionization non-equilibrium near the particle. Spatial distributions of electric current, electric potential, and electron flux around a single particle were calculated. The electric current flowing through the particle in the plasma was determined and compared with the model of the highly conducting particle in the uniform conducting media. The surface distribution and total heat flux density from plasma to the particle were studied. The range 10⁻⁵–10⁻⁴ m of particle radius and the range (0.5–2)×10⁷ A/m² of current density in unperturbed plasma, corresponding to the conditions of plasma transferred arc surfacing and plasma powder spheroidization, were considered. The electron temperature was assumed to be constant.</p>
