N2 - A plasma jet can be regarded as a multifunctional fluid, since it has high enthalpy, chemical reactivity and is easily controllable. Hence, it has been extensively utilized in plasma processing and in the new types of energy conversion systems. In these industrial applications, it is one of the effective and important methods for controlling precisely the characterization of plasma flow by applying the electromagnetic field. In the present study, a new numerical analysis of the continuum approach based on the two-temperature model for the description of a low-pressure plasma jet in the strong magnetic field is presented taking the temperature and pressure dependent and heterogeneous transport properties and the microscopic behavior of electrons into account. Numerical examples are shown to clarify the effect of the magnetic field on the thermofluid characteristics of heavy particles and plasma parameters such as electron number density and electron temperature in the nonequilibrium plasma jet. In addition, the effects of operating pressure and thermal boundary condition at the wall on the characteristics of the plasma jet are discussed.
