Turbulence appearance and non-appearance in thin fluid layers
Gregory Falkovich, Natalia Vladimirova
Flows in fluid layers are ubiquitous in industry, geophysics and astrophysics. Large-scale flows in thin layers can be considered two-dimensional (2d) with bottom friction added. H…
Evolution of inverse cascades and formation of precondensate in Gross-Pitaevskii turbulence in two dimensions
Natalia Vladimirova
Here we study how coherence appears in a system driven by noise at small scales. In the wave turbulence modeled by the Gross-Pitaevskii / nonlinear Schrödinger equation, we observe…
Reactive Rayleigh-Taylor Turbulence
M. Chertkov, V. Lebedev, N. Vladimirova
The Rayleigh-Taylor (RT) instability develops and leads to turbulence when a heavy fluid falls under the action of gravity through a light one. We consider this phenomenon accompan…
Self-Similarity and Universality in Rayleigh-Taylor, Boussinesq Turbulence
Natalia Vladimirova, Michael Chertkov
We report and discuss case study simulations of the Rayleigh-Taylor instability in the Boussinesq, incompressible regime developed to turbulence. Our main focus is on a statistical…
Flame Enhancement and Quenching in Fluid Flows
Natalia Vladimirova, Peter Constantin, Alexander Kiselev +2
We perform direct numerical simulations (DNS) of an advected scalar field which diffuses and reacts according to a nonlinear reaction law. The objective is to study how the bulk bu…
Model Flames in the Boussinesq Limit: The Effects of Feedback
N. Vladimirova, R. Rosner
We have studied the fully nonlinear behavior of pre-mixed flames in a gravitationally stratified medium, subject to the Boussinesq approximation. Key results include the establishm…
