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 …

Organized structures in turbulent jets can be modeled as wavepackets. These are
characterized by spatial amplification and decay, both of which are related to stability …

We consider the frequency domain form of proper orthogonal decomposition (POD), called
spectral proper orthogonal decomposition (SPOD). Spectral POD is derived from a space …

Informed by large-eddy simulation (LES) data and resolvent analysis of the mean flow, we
examine the structure of turbulence in jets in the subsonic, transonic and supersonic …

Response modes computed via linear resolvent analysis of a turbulent mean-flow field have
been shown to qualitatively capture characteristics of the observed turbulent coherent …

Coherent turbulent wave-packet structures in a jet at Reynolds number 460 000 and Mach
number 0.4 are extracted from experimental measurements and are modeled as linear …

We develop a method to estimate space–time flow statistics from a limited set of known data.
While previous work has focused on modelling spatial or temporal statistics independently …

The ability of linear stochastic response analysis to estimate coherent motions is
investigated in turbulent channel flow at the friction Reynolds number. The analysis is …

Streaks have been found to be an important part of wall-turbulence dynamics. In this paper,
we extend the analysis for unbounded shear flows, in particular a Mach 0.4 round jet, using …

Resolvent analysis is used to study the low-frequency behaviour of the laminar oblique
shock wave/boundary layer interaction (SWBLI). It is shown that the computed optimal gain …
