| Outline of Final Research Achievements |
A study of Disk-shaped MHD Accelerator and its achievement are obtained by unsteady quasi-1 dimensional numerical simulation, it was variation of cross sectional area for a certain channel length. Therefore it had a weak point which is severe to understand local variation. In this work, the purpose is to develop unsteady r-z 2D numerical simulation code, to confirm the simulation results and to investigate pressure gain at close to the MHD channel, plasma dynamics and influence to acceleration performance. As a result, governing equations, simulation scheme and its discretization are adapted to r-z 2D numerical simulation model. However it is necessary to work out development of numerical simulation code.
