In resolvent analyses of turbulent channel flows it has been common practice to neglect or
model the nonlinear forcing term that forms the input of the resolvent. However, the …

We extend the resolvent-based estimation approach recently introduced by Towne etal.(J.
Fluid Mech., vol. 883, 2020, A17) to obtain optimal, non-causal estimates of time-varying …

Self-similarity of wall-attached coherent structures in a turbulent channel at is explored by
means of resolvent analysis. In this modelling framework, coherent structures are …

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

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 …

Modelling the noise emitted by turbulent jets is made difficult by their acoustic inefficiency:
only a tiny fraction of the near-field turbulent kinetic energy is propagated to the far field as …

Spectral proper orthogonal decomposition (SPOD) is an increasingly popular modal
analysis method in the field of fluid dynamics due to its specific properties: a linear system …

Avoiding aliasing in time-resolved flow data obtained through high-fidelity simulations while
keeping the computational and storage costs at acceptable levels is often a challenge. Well …

An attempt to improve the accuracy of resolvent-based predictions by including velocity
correlations in the linear model is developed here. Closure assumptions for unresolved …

Large-eddy simulations of a flat-plate boundary layer, without a leading edge, subject to
multiple levels of incoming free-stream turbulence are considered in the present work …
