Resolvent-based tools for optimal estimation and control via the Wiener-Hopf formalism

Autor: Junoh Jung, Eduardo Martini Rodrigues da Silva, Aaron Towne, Peter Jordan, André Cavalieri

The application of control tools to complex flows frequently requires approximations, such as reduced-order models and/or simplified forcing assumptions, where these may be considered low-rank or defined in terms of simplified statistics (e.g. white

Vortex-sheet models of jets are widely used to describe the dynamics of modes, such as the Kelvin-Helmholtz instability and guided acoustic waves. However, it is seldom pointed out in the literature the absence of the free-stream acoustic modes in th
