Streak generation in viscosity-stratified wall-bounded flows
Anagha Madhusudanan, Simon J. Illingworth, Rama Govindarajan
Streamwise elongated flow structures, or streaks, dominate wall-bounded flows. We show that the renowned lift-up mechanism, that generates streaks, is significantly altered by visc…

Predicting burst events in a forced 2D flow: A wavelet-based analysis
Anagha Madhusudanan, Rich R. Kerswell
Predicting and perhaps mitigating against rare, extreme events in fluid flows is an important challenge. Due to the time-localised nature of these events, Fourier-based methods pro…

A resolvent-based perspective on the generation of Mach wave radiation from compressible boundary layers
Anagha Madhusudanan, Gregory Stroot, Beverley J. McKeon
We identify forcing mechanisms that separately amplify subsonic and supersonic features obtained from a linearized Navier-Stokes based model for compressible parallel boundary laye…
