Investigation of Turbulence in the Early Stages of a High Resolution Supernova Simulation
SESSION: Scientific Visualization Showcase Reception
EVENT TYPE: Scientific Visualization Showcases
TIME: 5:15PM - 7:00PM
AUTHOR(S):Robert Sisneros, Chris Malone, Stan Woosley, Andy Nonaka
ROOM:North Foyer
ABSTRACT:
Cosmologists have used the light curves of Type Ia supernovae (SN Ia) as tools for surveying vast distances. Previous simulations have used coarse resolution and artificial initial conditions that substantially influenced their outcome. Here, we have the unique advantage of being able to import the results from previous simulations of convection leading to ignition from our low Mach number code, MAESTRO, directly into our compressible code, CASTRO. These initial conditions include the location of ignition and the turbulence on the grid. In this video, we show the turbulence within the early bubble of a supernova via renderings of the magnitude of the vortic- ity within the simulation. We then focus on the highest values of the mag- nitude of vorticity to observe the formation of vortex tubes. The video is available here: http://www.ncsa.illinois.edu/∼sisneros/sc video.html
