Understanding dynamics and evaporation of fuel droplets in supercritical conditions
Abstract
Advanced propulsion systems like scramjets, detonation engines, and rocket engines operate at conditions exceeding the critical pressure and temperature of injected liquid fuels.1-3 Further, liquid fuel injected into high-speed compressed air breaks into microscale droplets.4 Dynamics of fuel microdroplets including evaporation, collision, breakup, and drag acceleration in supercritical and high-speed flows affects mixture formation and combustion. Fundamental understanding of the dynamics of fuel microdroplets in such extreme conditions is imperative to develop advanced propulsion systems with high performance. However, current numerical and experimental studies of microdroplet behavior still faces many challenges.
