Kinetic study of plasma detachment from a magnetic nozzle of high power thruster

چکیده مقاله

In this work, a two dimensional kinetic model based on Particle-In-Cell Monte Carlo Computation (PIC-MCC) simulation method is used to perform a parametric study of an ideal magnetic nozzle of a typical high power plasma thruster. The critical operating parameters i. e., applied magnetic field, gyro-velocity and initial axial velocity of ions are varied and their influences on the axial velocity of ions and their detachment in the plume region are studied. It is seen that increase in the velocity of ions causes their detachment from magnetic field lines and consequently, they will not return to the thruster. More flow attachment to the applied magnetic field lines is owing to higher magnetic fields. It is observed that the magnetic field affects the ions acceleration along axial position from nozzle throat. Moreover, ions in the proximity of the nozzle axis will get more acceleration
