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 …

This study establishes a continuous adjoint data assimilation model (CADA) for the
reproduction of global turbulent mean flow from a limited number of wall pressure …

Experimental measurements and numerical simulations of turbulent flows are characterized
by a tradeoff between accuracy and resolution. In this study, we combine accurate sparse …

OCEAN satellites detect the global sea area in a wide swath with high timeliness. It is of
great significance for humans to acquire ocean information and monitor ocean changes …

The flows around a NACA 0018 airfoil at a chord-based Reynolds number of case behaves
more like an amplifier and its nonlinear forcing is far less structured. The two cases suggest …

This paper proposes a new data assimilation method for recovering the high-fidelity
turbulent mean flow field around airfoil at high Reynolds numbers based on experimental …

The conceptual picture underlying resolvent analysis is that the nonlinear term in the Navier-
Stokes equations acts as an intrinsic forcing to the linear dynamics, a description inspired by …

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

This study establishes a compressible continuous adjoint data assimilation (C 2 ADA)
approach for reproducing a complete mean flow from sparse wall pressure observations …

We develop a framework for efficient streaming reconstructions of turbulent velocity
fluctuations from limited sensor measurements with the goal of enabling real-time …
