This work addresses one-dimensional evolution of a collisionless plasma next to a solid surface that is immersed into the plasma instantaneously. In particular, we consider how the self-similar rarefaction wave (Allen & Andrews, J. Plasma Phys., vol. 4, 1970, pp. 187–194) establishes dynamically and how the electron reflection from the surface modifies the structure of the rarefaction wave and the Debye sheath. We demonstrate that a sufficiently strong reflection eliminates the Debye sheath and changes the wall potential and the plasma flow parameters significantly. The paper presents numerical results that illustrate the developed analytical theory.

部分反射表面附近的等离子体鞘和前鞘发育

这项工作解决了在瞬间浸入等离子体的固体表面旁边的无碰撞等离子体的一维演化。特别是，我们考虑了自相似稀疏波（Allen & Andrews，J.等离子物理学。, 卷。4, 1970, pp. 187–194) 动态地建立了来自表面的电子反射如何改变稀疏波和德拜鞘的结构。我们证明了足够强的反射消除了德拜鞘并显着改变了壁电位和等离子体流动参数。本文提出的数值结果说明了已发展的分析理论。
