Hypersonic aerodynamics on thin bodies with interaction and upstream influence [PDF]

, 1994
In the fundamental configuration studied here, a steady hypersonic free stream flows over a thin sharp aligned airfoil or flat plate with a leading-edge shock wave, and the flow field in the shock layer (containing a viscous and an inviscid layer) is ...

Evolution of Supersonic Modes in Hypersonic High-Enthalpy Boundary Layer Transition

气体物理, 2023
With continuous expansion of flight speed and altitude domains, the high-temperature gas effects, especially the thermochemical non-equilibrium (TCNE) effects in hypersonic high-enthalpy boundary layers invalidated the calorically perfect gas (CPG ...

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.

Computation of thermochemical nonequilibrium flows around a simple and a double ellipse [PDF]

, 1991
The nonequilibrium viscous reactive flows over a simple and a double ellipse at a 30 degree angle of attack were computed. The geometry and the free stream conditions are given by INRIA/GAMNI/SMAI workshop test cases 6.2-2 and 6.2-4. The governing Navier-

Aerodisk Effect on Hypersonic Boundary Layer Transition and Heat Transfer of HIFiRE-5 Vehicle

Aerospace, 2022
The substantial aerodynamic drag and severe aerothermal loads, which are closely related to boundary layer transition, challenge the design of hypersonic vehicles and could be relieved by active methods aimed at drag and heat flux reduction, such as ...

Investigation of turbulence models with compressibility corrections for hypersonic boundary flows

Advances in Mechanical Engineering, 2015
The applications of pressure work, pressure-dilatation, and dilatation-dissipation (Sarkar, Zeman, and Wilcox) models to hypersonic boundary flows are investigated.
