Abstract

Two-fluid analytical models of hypersonic plasma plumes, which are of great relevance in many applications, including a recently presented space debris deorbiting system based on plasma beams known as Ion Beam Shepherd, are discussed. A generalized framework to derive self-similar models is provided, from which three particular models proposed in the literature are derived and compared. It is demonstrated that strict self-similarity is incompatible with the two-fluid model. The three existing models provide only quasi selfsimilar solutions, based on a constant axial velocity and the order of the error is one over the square Mach number. A preliminary analysis of the effects of the ambient magnetic field on the plume is carried out, pointing out that resistivity, plasma-induced fields and the 3D geometry of the plasma provide three mechanisms that counter magnetic deflection of the plume.
