Transient growth and resolvent analyses are routinely used to assess nonasymptotic
properties of fluid flows. In particular, resolvent analysis can be interpreted as a special case …

THE field of fluid mechanics involves a range of rich and vibrant problems with complex
dynamics stemming from instabilities, nonlinearities, and turbulence. The analysis of these …

Understanding, modeling and control of the high-speed wall-bounded transition and
turbulence not only receive wide academic interests but also are vitally important for high …

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 …

Direct numerical simulations, performed with a high-order spectral-element method, are
used to study coherent structures in turbulent pipe flow at friction Reynolds numbers. The …

The dynamics of wind-generated water waves in the principal stage of the Phillips theory
(Phillips, J. Fluid Mech., vol. 2, 1957, pp. 417–445) is investigated by a combined numerical …

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

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 …

We analyse the inter-scale transfer of energy for two types of plane Poiseuille flow: the P4U
exact coherent state of Park & Graham (J. Fluid Mech., vol. 782, 2015, pp. 430–454) and …
