State-to-state approach in hypersonic thermochemical nonequilibrium flow simulations: a review [PDF]

Frontiers in Chemistry
Thermochemical nonequilibrium flows play a critical role in shaping the aerothermal environment of hypersonic vehicles and therefore strongly influence the analysis and design of thermal protection systems (TPS).

Numerical Investigation on Mechanisms of MHD Heat Flux Mitigation in Hypersonic Flows

Aerospace, 2022
Numerical simulations of hypersonic magnetohydrodynamics (MHD) flow over a typical sphere–cone blunt body are carried out based on the assumption of a low magnetic Reynolds number. The effects of an external dipole magnetic field on the surface heat flux

Gas Kinetic Scheme Coupled with High-Speed Modifications for Hypersonic Transition Flow Simulations [PDF]

Entropy
The issue of hypersonic boundary layer transition prediction is a critical aerodynamic concern that must be addressed during the aerodynamic design process of high-speed vehicles. In this context, we propose an advanced mesoscopic method that couples the
