The Bohm criterion for a collisional plasma sheath in an oblique magnetic field

摘要: 采用双流体模型研究了斜磁场作用下的碰撞等离子体鞘层的玻姆判据,讨论了磁场对鞘层玻姆判据的影响.结果表明:玻姆判据存在上限和下限,磁场强度、角度以及离子进入鞘层的状态都对离子马赫数的取值范围有影响.

Abstract: The Bohm criterion for a collisinal plasma sheath in an oblique magnetic field is investigated with a two-fluid model.It is shown that the upper and lower limits for the sheath criterion exist.And the range of the ion Mach number depends on the magnetic field and the incidence status of the ions.
