Progress in RANS-based local correlation transition models for hypersonic flows: A review [PDF]
International Journal of Fluid EngineeringPrecise estimation of the location and magnitude of boundary layer transition is essential for the exact computation of aero-thermodynamics and the performance of hypersonic vehicles. Compared with resource-intensive methods such as large eddy simulation,

Data-driven nonlinear constitutive relations for rarefied flow computations
Advances in Aerodynamics, 2021 To overcome the defects of traditional rarefied numerical methods such as the Direct Simulation Monte Carlo (DSMC) method and unified Boltzmann equation schemes and extend the covering range of macroscopic equations in high Knudsen number flows, data ...

Hypersonic limit of two‐dimensional steady compressible Euler flows passing a straight wedge [PDF]
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2019 We formulate a problem on hypersonic limit of two‐dimensional steady non‐isentropic compressible Euler flows passing a straight wedge. It turns out that the Mach number of the upcoming uniform supersonic flow increases to infinity may be taken as that ...

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
