| Popis: | We have been studying the Magneto Plasma Sail (MPS) by using 3D hybrid numerical simulation code. There are two key issues of MPS research, one is the possibility of magnetic inflation, and the other is the analysis of the interaction between the solar wind and the artificially generated magnetic field. We simulated the interaction between the solar wind and dipole magnetic field in pure-Magsail and compared with the drag coefficient obtained by using other hybrid code. And we simulated the magnetic inflation by injected plasma. Plasma is injected from the region located in 1.0 m from the center of the coil. Plasma is injected in radial direction with N = 10(exp 20) /cu m and v = 4.0 km/s. Next we simulated the interaction between the solar wind and inflated magnetic field by the plasma injection. The initial magnetic field is produced at the center of the system as dipole configuration. The solar wind flows only in the positive Z direction with 5 x 10(exp 6) /cu m density and 400 km/s velocity. The Ar plasma with 5 x 10(exp 9) /cu m density and 20 km/s velocity is injected isotropically. We will show these simulation results and list up the difficulties of numerical simulation of MPS in each theme. And finally I will make a brief summary and talk about the Future plan. 資料番号: AA0063157011 レポート番号: JAXA-SP-06-014 |
