title = "Analysis of Hypersonic Flow Behind an Isolated Roughness Element Using Kinetic Methods",
abstract = "Present work investigates global stability of hypersonic flow behind an isolated roughness element using kinetic methods and data-driven techniques. The goal of this contribution is to investigate influence of the shock layer on the flow stability at free-stream Mach number of 6. Two-dimensional analysis suggests that the least-stable global flow eigenmode is a stationary one with multiple mechanisms being present. The work continues to conduct TriGlobal stability analysis on the shock layer and wake behind roughness element as well as quantifying non-equilibrium effects and linking them to the stability properties of the considered flow.",
