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.
