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 …

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 …

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 …

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 …

We use Navier–Stokes-based linear models for wall-bounded turbulent flows to estimate
large-scale fluctuations at different wall-normal locations from their measurements at a …

Many turbulent flows exhibit time-periodic statistics. These include turbomachinery flows,
flows with external harmonic forcing and the wakes of bluff bodies. Many existing techniques …

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 …

The present paper reports on the ability of neural networks (NN) and linear stochastic
estimation (LSE) tools to predict the evolution of skin friction in a minimal turbulent channel …

Stochastic linear modeling proposed in Tissot, Mémin, and Cavalieri [J. Fluid Mech. 912,
A51 (2021) 0022-1120 10.1017/jfm. 2020.1168] is based on classical conservation laws …

Eigenvectors of the observability and controllability Gramians represent responsive and
receptive flow structures that enjoy a well-established connection to resolvent forcing and …
