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…
Capturing the Fire: Flame Energetics and Neutronizaton for Type Ia Supernova Simulations
A. C. Calder, D. M. Townsley, I. R. Seitenzahl +6
We develop and calibrate a realistic model flame for hydrodynamical simulations of deflagrations in white dwarf (Type Ia) supernovae. Our flame model builds on the advection-diffus…
Type Ia Supernovae: An Asymmetric Deflagration Model
A. C. Calder, T. Plewa, N. Vladimirova +2
We present the first high-resolution three-dimensional simulations of the deflagration phase of Type Ia supernovae that treat the entire massive white dwarf. We report the results…
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…
