Three-dimensional receptivity of hypersonic sharp and blunt cones to free-stream planar waves using hierarchical input-output analysis
David A. Cook, Joseph W. Nichols
Understanding the receptivity of hypersonic flows to free-stream disturbances is crucial for predicting laminar to turbulent boundary layer transition. Input-output analysis as a r…
Linear Analysis of Boundary-Layer Instabilities on a Finned-Cone at Mach 6
Daniel B. Araya, Neal P. Bitter, Bradley M. Wheaton +8
Boundary-layer instabilities for a finned cone at Mach=6, [m], and zero incidence angle are examined using linear stability methods of varying fidelity…
Transient growth analysis of oblique shock wave/boundary-layer interactions at Mach 5.92
Anubhav Dwivedi, Nathaniel Hildebrand, Joseph W. Nichols +2
We study physical mechanisms that trigger transient growth in a high-speed spatially-developing laminar boundary layer that interacts with an oblique shock wave. We utilize an appr…
Reattachment streaks in hypersonic compression ramp flow: an input-output analysis
Anubhav Dwivedi, G. S. Sidharth, Joseph W. Nichols +2
We employ global input-output analysis to quantify amplification of exogenous disturbances in compressible boundary layer flows. Using the spatial structure of the dominant respons…
Input-output analysis of Mach 0.9 jet noise
Jinah Jeun, Joseph W. Nichols
We examine amplifying behavior of small perturbations about Reynolds-averaged Navier-Stokes solutions (RANS) of a subsonic turbulent jet using input-output (I/O) analys…
Simulation and stability analysis of oblique shock wave/boundary layer interactions at Mach 5.92
Nathaniel Hildebrand, Anubhav Dwivedi, Joseph W. Nichols +2
We investigate flow instability created by an oblique shock wave impinging on a Mach 5.92 laminar boundary layer at a transitional Reynolds number. The adverse pressure gradient of…
