A feature of laminar separated flows which occurs naturally, even at rather small Reynolds
numbers, is their instability. Thus, a mean flow pattern in a separated flow as well as its …

We propose a novel cluster-based reduced-order modelling (CROM) strategy for unsteady
flows. CROM combines the cluster analysis pioneered in Gunzburger's group (Burkardt …

This paper summarizes experimental studies of incompressible elliptic jets of different
aspect ratios and initial conditions, and effects of excitations at selected frequencies and …

The Kelvin–Helmholtz rollup of three-dimensional temporally evolving plane mixing layers
with an initial Reynolds number of 500 based on vorticity thickness and half the velocity …

The evolution of three-dimensional temporally evolving plane mixing layers through as
many as three pairings has been simulated numerically. All simulations were begun from a …

Spatiotemporal dynamics resulting from the interaction of two instabilities breaking,
respectively, spatial and temporal symmetries are studied in the framework of the amplitude …

We propose an automatable data-driven methodology for robust nonlinear reduced-order
modelling from time-resolved snapshot data. In the kinematical coarse-graining, the …

In a stably stratified shear layer, multiple competing instabilities produce sensitivity to small
changes in initial conditions, popularly called the butterfly effect (as a flapping wing may …

This book is a complete revision of the part of Monin & Yaglom's famous two-volume work"
Statistical Fluid Mechanics: Mechanics of Turbulence" that deals with the theory of laminar …

The dynamics of coherent structure interactions, in particular the jet column mode of vortex
pairing, in the near field of an elliptic jet have been investigated using hotwire …
