Extraction of Droplet Genealogies from High-Fidelity Atomization Simulations

Many research groups are performing high-fidelity simulations of atomizing jets that are taking advantage of the continually increasing computational resources and advances in numerical methods. These high-fidelity simulations produce extremely large data-sets characterizing the flow and giving the ability to gather a better understanding of atomization. One of the main challenges with these large data sets is the ability to extract relevant physics from them. With this physics extraction technique the genealogy of droplets created as the coherent liquid core continually breaks into droplets and ligaments which may proceed to break up further are provided. Along with the ancestry of the droplets information such as droplet size, shape, flow field characteristics, etc. will be stored in a database. Allowing the information to be readily queried to assist in the development and testing of low-fidelity atomization models that agree with the physics predicted by high-fidelity simulations.
