Abstract : This report provides a general description of the results of research studies aimed at providing a basic understanding of turbulent spray combustion. The environment in a liquid rocket engine can lead to complex flow/flame/droplet interactions which can substantially modify the droplet evaporation and combustion processes which can affect the stability characteristics of the rocket engine. The various studies conducted during this research project were: spray combustion in stagnation-point flow, thermo-diffusive flame instabilities, the influence of vorticity on flame stability/stabilization, non-planar flame configurations. Areas of future research are presented along with a discussion as to how the results of the investigation can be applied to liquid rocket engine combustion.
