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…

Onset of separation unsteadiness in hypersonic shock boundary layer interaction on a cone-step
Chase Jenquin, Eric L. Cui, Anubhav Dwivedi +2
Shock-boundary layer interactions (SBLI) on hypersonic cone step flows exhibit a range of intrinsic unsteady behaviors, from shear-layer oscillations to large-scale pulsations. Thi…
