NUMERICAL-SIMULATION OF A NONEQUILIBRIUM PLASMA-JET IN AN APPLIED MAGNETIC-FIELD USING 3-FLUID MODEL (REPRINTED FROM TRANS OF THE JAPAN SOCIETY OF MECHANICAL-ENGINEERS, VOL 60, PG 3072, 1994)

A three-fluid model is applied for the numerical simulation of the axi symmetric flow and temperature fields in a nonequilibrium argon plasma jet which can be controlled by applying an electromagnetic field. The effects of the magnetic field on the characteristics of each plasma s pecies, i.e., electrons, positive ions, and neutral particles, should be accurately clarified. The three-fluid model applied here can clarif y the behavior of each plasma species. Equations of conservation for e ach plasma species coupled with tire generalized Ohm's law, Maxwell's equations, and the equation of state are simultaneously solved taking variable transport properties into account. It is shown that the elect ron temperature is the highest and the electron velocity is strongly i nfluenced by the magnetic field. Furthermore, the momentum and energy exchanges through electrons can be varied even by a small magnetic flu x.
