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…
