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 …

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 …

We present a publicly accessible database specifically designed to aid in the conception,
training, demonstration, evaluation, and comparison of reduced-complexity models for fluid …

This paper details the statistical and time-resolved analysis of the relationship between the
near-field pressure fluctuations of unforced, subsonic free jets (0.4≤ M≤ 0.6) and their far …

Resolvent analysis is a powerful tool for modelling and analysing transitional and turbulent
flows and, in particular, for approximating coherent flow structures. Despite recent …

We employ a resolvent-based methodology to estimate velocity and pressure fluctuations
within turbulent channel flows at friction Reynolds numbers of approximately 180, 550 and …

An analysis of the statistics of the nonlinear terms in resolvent analysis is performed in this
work for turbulent Couette flow at Reynolds number 400. Data from a direct numerical …
