State estimation of Rayleigh-Bénard convection with reduced-order models
Enrique Flores-Montoya, André F. C. da Silva, André V. G. Cavalieri
In this work, we develop a state estimation framework for two-dimensional Rayleigh-Bénard (RB) convection that combines a stable Galerkin reduced-order model (ROM) with an extende…

Galerkin reduced order model for two-dimensional Rayleigh-Bénard convection
Enrique Flores-Montoya, André V. G. Cavalieri
In this work, Galerkin projection is used to build reduced-order models (ROM) for two-dimensional Rayleigh-Bénard (RB) convection with no-slip walls. We compare an uncoupled proje…

Coherent structures in axis-switching elliptical jets
Naia Suzuki, André V. G. Cavalieri, Daniel M. Edgington-Mitchell +1
Coherent structures in aspect ratio 2, axis-switching elliptical jets are studied using direct numerical simulation (DNS). Three different datasets are studied with varying near-no…
