Images from a large, 3-D, multi-scale, multi-physics simulation of buoyancy-driven turbulent nuclear combustion carried out on the Intrepid supercomputer at the Argonne Leadership Computing Facility. The three frames show different physical properties of the reactive flow, which provide different insights into its nature. In the simulation, an initially planar flame surface with a multi-mode sinusoidal perturbation burns its way upward through a stratified medium under density and pressure conditions that are characteristic of the degenerate material near the center of a near-Chandrasekhar mass carbon/oxygen white dwarf star. Gravity is directed downward. The left image shows the flame surface, which is tracked using a scalar advection-diffusion-reaction equation. The middle frame shows a volume rendering of the velocity field that is generated at the flame surface; the magnitude of the turbulent velocities decreases behind the flame front over a length scale that is comparable to the size of the largest eddies in the flow. The right frame shows the kinetic energy the flame generates. This work was carried out by the DOE NNSA ASC/Alliance Center for Astrophysical Thermonuclear Flashes and the NSF Physics Frontier Joint Institute for Nuclear Astrophysics at The University of Chicago. The computational resources needed to do the simulation were awarded to the Flash Center under the DOE Office of Science INCITE program. The images were produced by the Futures Lab at Argonne National Laboratory.

New Argonne algorithm increases accuracy of air-pollution predictions

Scientists, city officials and regulators all desire an effective and accurate way not only to measure air quality but also to predict where pollution "hot spots" will occur and plan for additional control strategies. Environmental scientist Rao Kotamarthi helped to develop a computer algorithm that quickly and accurately assimilates observational data into climate models to generate more reliable forecasts.
