The role of entropic-instabilities in laminar-turbulent transition on a blunted flat plate
Hemanth Goparaju, Datta V. Gaitonde
The effects of entropic-instabilities on the laminar-turbulent transition dynamics of a blunted flat plate at Mach~ are numerically investigated through linear and nonlinear app…
