要約(英語): To analyze the pulse interval dependence on fluid behavior in a linear MHD accelerator, we simulated numerically the behavior by using a third-order upwind scheme combined with MmB method. To understand the fluid behavior in the MHD accelerator, we evaluate the temporal-spatial fluid evolutions in the MHD channel. It indicates that the characteristics curve in the MHD channel determines the hydrodynamics behavior. These estimations almost correspond to the timing of the peak incremental thrust. On the other hand, the average incremental thrust is improved with prolonging the interval time. Nevertheless, it is possible to apply the second current pulse with the arbitrary interval time, because the change of the average incremental thrust is small.
