Numerical Simulations of Plume and Pool Fire Instabilities using Adaptive Mesh Refinement Nicholas Wimer, University of Colorado Boulder Caelan Lapointe, University of Colorado Boulder Marcus Day, Center for Computational Science and Engineering, Lawrence Berkeley National Lab Amanda Makowiecki, University of Colorado Boulder Jeffrey Glusman, University of Colorado Boulder John Daily, University of Colorado Boulder Gregory Rieker, University of Colorado Boulder Peter Hamlington, University of Colorado Boulder DOI: Visualizations from numerical simulations (large eddy and direct numerical simulations) are shown for a one-meter diameter methane pool fire and a one-meter diameter helium plume. These flows are both buoyancy dominated and exhibit similar instabilities and behavior. See other videos from the 2018 Gallery of Fluid Motion:
