The paper presents a numerical model of mixing of plasma species inside the discharge and in the near outlet regions of the hybrid-stabilized argon-water electric arc. Mixing of water and argon plasma species is considered in the model using the so called combined diffusion coefficients method. Diffusion processes due to pressure, temperature and concentration gradients and due to an external electric field are taken into account. Results of calculation indicate inhomogeneous mixing of argon and oxygen-hydrogen species for all currents. Temperature and ordinary (concentration) diffusions are the principal contributions in the argon mass diffusion flux.
