Meandering dynamics of streamwise vortex pairs in afterbody wakes
Rajesh Ranjan, J. -Ch. Robinet, Datta Gaitonde
Wakes of upswept afterbodies are often characterized by a counter-rotating streamwise vortex pair. The unsteady dynamics of these vortices are examined with a spatio-temporally res…

Instabilities and transition in cooled-wall hypersonic boundary layers
S. Unnikrishnan, Datta V. Gaitonde
Wall cooling has substantial effects on the development of instabilities and transition processes in hypersonic boundary layers (HBLs). A sequence of linear stability theory, two-d…

Linear, nonlinear and transitional regimes of second mode instability
S. Unnikrishnan, Datta V. Gaitonde
The 2D second-mode is a potent instability in hypersonic boundary layers (HBLs). We study its linear and nonlinear evolution, followed by its role in transition and eventual breakd…
