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 mi xing with the secondary gas in an applied magnetic field. The velocity and the gas temperature fields and also the plasma parameters in a non-equilibr ium 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 k-epsilon model, two temperature model coupled with Ohm ic equations. The concentration field is also evaluated using species conse rvation equation. It can be examined numerically how the thermofluid and di ffusion characteristics, and plasma parameters of a non-equilibrium Ar plas ma jet are enhanced or controlled by mixing with He and by applying a magne tic field.
