| Abstract | ||
| One-dimension (1D) magnetohydrodynamic(MHD) model is employed to study physics of the acceleration process inside the cylindrical Hall thruster is independently designed. And some influencing factors which are the plasma ionization, neutralization, collision, Bohm diffusion as well as anode sheath .etc are considered. Using the Runge-Kutta method obtains the distributions of the speed, ion number density, temperature .The ion number density increases, but near exit drops and the neutral number density gradually reduces in the channel. The ion speed reaches the maximum at exit and the electron velocity has the great gradient distribution in the downriver. These distributions are relevant with electromagnetic distribution, collision and electronic impedance. Finally make the analysis the connection between electron temperature distribution and velocity as well as magnetic field. | ||
