内容記述 | Electromagnetic interaction between the solar wind and sub-scale magnetic sails was numerically analyzed to assess reaction forces exerted on the magnetic sail when its characteristic scale is reduced below the continuum limit at which the magneto-hydrodynamic approximations for the plasma flow fail. The hybrid particle-in-cell (PIC) method was used to take the finite Larmor-radius effects into consideration. The magnetic dipole intensity was changed so that the characteristic size of the magnetic sail changed from several kilometers to few thousand kilometers. The results show that the drag coefficient of the magnetic sail based on the representative radius of the magneto-hydrodynamic interaction decreases as the ratio of the ion Larmor radius to this representative radius becomes greater than unity. An approximate formula to compute the drag coefficient in a wide range of magnetic sail dimension has been developed. | |||||
