An increase of practical applications has led to increase in interest for development of SC flow modelling.Correlation between experiment and simulation isproblematic as taking measurements of fluids under SC conditions has proven challenging. Measurement resolution is also a challenging consideration,especially for injection of sprays under SC mixing conditions due to the various scales needed to be considered. the differing mixing regime of SC fluids, greaterdifficulty in measurement of supercritical fluids, and scaling of flows has made it problematic, thus far, for accurate CFD models of entire jet formations to beformulated. It is proposed for this project that a unified description the internal nozzle and subsequent jet spray breakup formation through the development ofadvanced numerical tools and by treating the development of droplet and ligament surface as a continuous evolution process.
