Title: Verification Study of Buoyancy-Driven Turbulent Nuclear Combustion

Buoyancy-driven turbulent nuclear combustion determines the rate of nuclear burning during the deflagration phase (i.e., the ordinary nuclear flame phase) of Type Ia supernovae, and hence the amount omore »f nuclear energy released during this phase. It therefore determines the amount the white dwarf str expands prior to initiation of a detonation wave, and so the amount of radioactive nickel and thus the peak luminosity of the explosion. However, this key physical process is not fully understood. To better understand this process, the Flash Center has conducted an extensive series of large-scale 3D simulations of buoyancy-driven turbulent nuclear combustion for three different physical situations. This movie shows the results for some of these simulations.
