Droplet and Supercritical Flame Dynamics in Propulsion

Abstract

The present program is concerned with the dynamics of droplet collision and flame-flow interaction that are of relevance to liquid-fueled turbulent combustion in high-pressure propulsive devices. The investigation during the reporting period involved six projects, namely: (1) Formulation of a comprehensive theory of the dynamics of binary droplet collision, especially in predicting the experimentally observed bouncing and coalescence phenomena; (2) Computational investigation of the gasification mechanism of multicomponent droplets, demonstrating that at elevated pressures the influence of liquid-phase mass diffusion is weakened; (3) A comprehensive study on the influence of elevated pressure on chemical kinetics; (4) Formulation of a theory of acoustic-flame resonance; (5) transition to detonation of an accelerating expanding flame; (6) computational simulation of the flame stabilization in a nozzle-generated flow.
