Optimized parametric inference for the inner loop of the Multigrid Ensemble Kalman Filter
Gabriel Moldovan, Guillaume Lehnasch, Laurent Cordier +1
Essential features of the Multigrid Ensemble Kalman Filter (G. Moldovan, G. Lehnasch, L. Cordier, M. Meldi, A multigrid/ensemble Kalman filter strategy for assimilation of unsteady…
Resolvent-based tools for optimal estimation and control via the Wiener-Hopf formalism
Eduardo Martini, Junoh Jung, André V. G. Cavalieri +2
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 conside…
Shock-induced cavitation and wavefront analysis inside a water droplet
Luc Biasiori-Poulanges, Hazem El-Rabii
The objective of the present study is to develop a basic understanding of the interaction of shock waves with density inhomogeneities. We consider here the particular instance of a…
Artificial intelligence control of a turbulent jet
Yu Zhou, Dewei Fan, Bingfu Zhang +2
An artificial intelligence (AI) control system is developed to maximize the mixing rate of a turbulent jet. This system comprises six independently operated unsteady minijet actuat…
Modal and nonmodal stability analysis of electrohydrodynamic flow with and without cross-flow
Mengqi Zhang, Fulvio Martinelli, Jian Wu +2
We report the results of a complete modal and nonmodal linear stability analysis of the electrohydrodynamic flow (EHD) for the problem of electroconvection in the strong injection…
Optimal Nonlinear Eddy Viscosity in Galerkin Models of Turbulent Flows
Bartosz Protas, Bernd R. Noack, Jan Östh
We propose a variational approach to identification of an optimal nonlinear eddy viscosity as a subscale turbulence representation for POD models. The ansatz for the eddy viscosity…
