From oblique-wave forcing to streak reinforcement: A perturbation-based frequency-response framework
DuÅ¡an BožiÄ, Anubhav Dwivedi, Mihailo R. JovanoviÄ
We develop a perturbation-based frequency-response framework for analyzing amplification mechanisms that are central to subcritical routes to transition in wall-bounded shear flows…

Numerical Bow Shock Instabilities in Inert Polyatomic Gases
G. S. Sidharth, Anubhav Dwivedi
We investigate inviscid numerical instabilities that arise in simulations of axisymmetric flow over a hypersonic sphere in an inert, calorically perfect gas at low specific heat ra…
