| Research Abstract |
A computational magnetohydrodynamic (MHD) code for analyzing plasma characteristics in inductively coupled high frequency plasma tunnels has been developed in this study. Influences of input power and frequency of high-frequency power source on the characteristics of inductively coupled plasma have been clearly understood from numerical simulations using the computational code. Three-dimensional numerical simulations of a cylindrical-shaped MHD accelerator have been carried out, and the numerical simulations have revealed that the MHD interaction induces three-dimensional flow structures as well as accelerates plasma flow. Test runs of a small-scale inductively coupled plasma jet facility fabricated in the present study have been conducted under the condition without applying the magnetic field, and then it has been confirmed from the test runs that the facility can produce super-sonic plasma flow.
