Numerical Simulation of Mixing Effect on a Non-equilibrium Plasma Jet in an Applied Magnetic Field

The present study describes the numerical model to control the thermofluid characteristics and plasma parameters of a non-equilibrium plasma jet by mixing with the scondary gas in an applied magnetic field. The velocity and the gas temperature fields and also the plasma parameters in a non-equilibrium Ar/He plasma jet are obtained by solving the axisymmetric turbulent 2-D MHD equations taking into account the variable transport properties of gas mixtures and using κ-ε model, two-temperature model coupled with Ohmic equations. The concentration field is also evaluated using species conservation equation. It can be examined numerically how the thermofluid and diffusion characteristics, and plasma parameters of a non-equilibrium Ar plasma jet are enhanced or cotrolled by mixing with He and by applying a magnetic field.
