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…
