SIMPLE aerodynamic configurations under even modest conditions can exhibit complex
flows with a wide range of temporal and spatial features. It has become common practice in …

It is common for jets of fluid to interact with crossflow. This article reviews our understanding
of the physical behavior of this important class of flow in the incompressible and …

We present a technique for describing the global behaviour of complex nonlinear flows by
decomposing the flow into modes determined from spectral analysis of the Koopman …

The decomposition of experimental data into dynamic modes using a data-based algorithm
is applied to Schlieren snapshots of a helium jet and to time-resolved PIV-measurements of …

This article reviews linear instability analysis of flows over or through complex two-
dimensional (2D) and 3D geometries. In the three decades since it first appeared in the …

The dynamic mode decomposition (DMD) is a data-decomposition technique that allows the
extraction of dynamically relevant flow features from time-resolved experimental (or …

The jet in crossflow or transverse jet has been studied extensively because of its relevance
to a wide variety of flows in technological systems, including fuel or dilution air injection in …

This review article addresses the dynamics and control of low-frequency unsteadiness, as
observed in some aerodynamic applications. It presents a coherent and rigorous linearized …

The jet in crossflow, or transverse jet, is a flowfield that has relevance to a wide range of
energy and propulsion systems. Over the years, our group's studies on this canonical …

Research in modern data-driven dynamical systems is typically focused on the three key
challenges of high dimensionality, unknown dynamics and nonlinearity. The dynamic mode …
