Journal ArticleDOI
Direct Numerical Simulation on the Receptivity, Instability, and Transition of Hypersonic Boundary Layers
Xiaolin Zhong,Xiaowen Wang +1 more
TL;DR: In the 20 years since the review by Kleiser & Zang (1991) on the direct numerical simulation (DNS) of the boundary-layer transition, significant progress has been made on DNS in the hypersonic flow regime and in the spatial DNS approach as discussed by the authors.
Journal ArticleDOI
Numerical investigation of the development of three-dimensional wavepackets in a sharp cone boundary layer at Mach 6
TL;DR: In this paper, the second-mode axisymmetric disturbance waves were identified as the dominant wave within the resulting wavepacket, which consisted of a wide range of disturbance frequencies and wavenumbers, and the response of flow to the large-amplitude pulse disturbances indicated the presence of a fundamental resonance mechanism.
Journal ArticleDOI
Direct Numerical Simulation Of Hypersonic Boundary-Layer Transition Over A Blunt Cone
Xinliang Li,Dexun Fu,Yanwen Ma +2 more
TL;DR: In this article, the velocity and pressure fluctuations at different streamwise locations are analyzed and compared with the linear stability theory, and the second-mode disturbance wave is deemed to be the dominating disturbance wave because the growth rate of the second mode is much higher than the first mode.
Journal ArticleDOI
Secondary instabilities of Görtler vortices in high-speed boundary layer flows
TL;DR: Li et al. as mentioned in this paper investigated the relationship between the dominant mode (sinuous or varicose) and the spanwise wavenumber of Gortler vortices found in incompressible flows.
Journal ArticleDOI
Second Mode Suppression in Hypersonic Boundary Layer by Roughness: Design and Experiments
Kahei Danny Fong,Xiaowen Wang,Yuet Huang,Xiaolin Zhong,Gregory McKiernan,Roy A. Fisher,Steven P. Schneider +6 more
TL;DR: In this paper, the effect of surface roughness on the transition of a hypersonic boundary-layer is investigated, and it is shown that roughness increases the delay of the transition.

On the Many Faces of Transition
TL;DR: For a given shear-layer geometry the high-Reynolds-numbers turbulent flows possess strong, stable in-the-large, nearly universal features associated with the large number of degrees of freedom in the flows as mentioned in this paper.
Journal ArticleDOI
Interaction of Linear Waves with Oblique Shock Waves
J. F. McKenzie,K. O. Westphal +1 more
TL;DR: Linear wave interaction with oblique shock waves, noting dependence of transmission, reflection and generation coefficients on Mach number was studied in this paper, where linear wave interaction was shown to have a strong dependence on the Mach number.
Journal ArticleDOI
Boundary-Layer Receptivity to Long-Wave Free-Stream Disturbances
TL;DR: In this article, the early stages of boundary layer transition are treated as a small perturbation of an appropriate mean flow, and a variety of wavelength-reduction mechanisms able to couple the longwavelength, freestream disturbances to the comparatively short Tollmien-Schlichting waves are discussed.
Journal ArticleDOI
Turbulence amplification in shock-wave boundary-layer interaction
TL;DR: In this article, three primary turbulence amplifier-generator mechanisms are identified and shown, by linear analysis, to be responsible for turbulence amplification across a shock wave in excess of 100% of the incident turbulence intensity.
