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 …

Advanced measurement techniques and high-performance computing have made large
data sets available for a range of turbulent flows in engineering applications. Drawing on …

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 …

Three amplification mechanisms present in turbulent jets, namely lift-up, Kelvin–Helmholtz
and Orr, are characterized via global resolvent analysis and spectral proper orthogonal …

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 …

In this work, the linear responses of turbulent mean flow to both harmonic and stochastic
forcing are investigated for supersonic channel flow. Well-established universal relations are …

Resolvent analysis is a powerful tool that can reveal the linear amplification mechanisms
between the forcing inputs and the response outputs about a base flow. These mechanisms …

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 …

The predictions obtained from resolvent analysis with and without an eddy viscosity model
for turbulent channel flow at Re τ= 550 are compared to direct numerical simulation data to …

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 …
