The DeepWater Horizon incident, a sustained release of hydrocarbons at a water depth of 1.5km, was an entirely unprecedented, anthropomorphic environmental event. Accurate predictive modeling of any future catastrophe requires fundamental leaps in our understanding of the overall transport, evolution and ultimate fate of hydrocarbons from the release point, through the water column and towards the shore. The primary goal of the present research to gain this understanding, using the resources of the HPCC as a computational fluid dynamics laboratory in which to conduct experiments on the dynamics of turbulent, multi-phase (oil-gas-seawater)  mixtures.

SALK, the Cray machine, has been the primary computational platform for running the large-scale (100-1,000 core) jobs, including turbulence resolving simulations using the highly scalable NEK-5000 Navier-Stokes solver, locally written Co-Array Fortran codes for transport studies with available ocean model outputs, and Co-Array Fortran codes for evolving very large, coupled point-particle, statistical mechanical systems.
 

Appel, running the highly-scalable Gerris Flow Solver package, serves as the primary platform for direct numerical simulations of turbulence-droplet dynamics in multi-phase atomization studies.
