Electron losses in hypersonic flows [PDF]
Physics of Fluids, 2022 The first comprehensive study of electron gains and losses in hypersonic air flows including the full coupling between non-neutral plasma sheaths and quasi-neutral plasma flows is presented here. This is made possible by the use of advanced numerical methods that overcome the stiffness associated with plasma sheaths.

A Unified Asymptotic Theory of Supersonic, Transonic, and Hypersonic Far Fields
Axioms, 2022 The problems of steady, inviscid, isentropic, irrotational supersonic plane flow passing a body with a small thickness ratio was solved by the linearized theory, which is a first approximation at and near the surface but fails at far fields from the body.
