Stability of Supersonic Boundary Layers on a Cone at an Angle of Attack
The stability and receptivity of three-dimensional supersonic boundary layers over a 7 ° sharp tipped straight cone at an angle of attack of 4.2° is numerically investigated at a free stream Mach number of 3.5 and at two high Reynolds numbers, 0.25 and 0.50*10 6/inch. The generation and evolution of stationary crossflow vortices are also investigated by performing simulations with three-dimensi...
متن کاملReal-Gas and Surface-Ablation Effects on Hypersonic Boundary-Layer Instability over a Blunt Cone
There has been little research into surface-ablation effects on hypersonic boundary-layer instability, and the current understanding of real-gas effects on hypersonic boundary-layer instability still contains uncertainties. The objective of the current work was to analyze the hypersonic boundary-layer transition process using linear-stability theory, inwhich surface ablation, aswell as real-gas...
متن کاملOn the stability of the compressible boundary-layer flow over a rotating cone
We investigate the type I modes of instability within the compressible boundary-layer flow over a rotating cone, defined by general half angle ψ. The work extends previous studies into the compressible rotatingdisk flow (ψ = 90o) and incompressible rotating-cone flows. Generalised compressible von Kármán equations are established and solved numerically to give the laminar-flow profiles. We then...
متن کاملNumerical Simulation of Shock-Wave/Boundary/Layer Interactions in a Hypersonic Compression Corner Flow
Numerical results are presented for the shock-boundary layer interactions in a hypersonic flow over a sharp leading edge compression corner. In this study, a second- order Godunov type scheme based on solving a Generalized Riemann Problem (GRP) at each cell interface is used to solve thin shear layer approximation of laminar Navier-Stokes (N-S) equations. The calculated flow-field shows general...
