Abstract
ABSTRACT: Development of advanced multi-angle illumination and multi-dimensional image correlation strategies set forth in this proposal will be instrumental in revealing and gaining a better understanding of the complexities of fuel injection, spray formation and spray dynamics associated with modern propulsion and combustion systems. Implementation of evolving highly complex illumination and computationally intensive imaging and image processing methodologies promise to extend our observations and measurements into the depths of spray formation and dynamical processes in dense spray environments. From a phenomenological and physical point of view, it is evident that we must observe and understand the entire spray flow field including how the liquid breaks up to form droplets, the two-phase air-fuel mixing that takes place, vaporization and reaction of the fuel, and the formation of pollutants. Currently, coupling of the fuel spray fluid mechanics, gas phase mixing, and chemistry which are highly important aspects of the process remain poorly understood. There continues to be a growing recognition that attaining a greater understanding of these complexities in the dynamics of the spray formation and associated transient processes can lead to development of methods for attaining greater ignition reliability, combustion and propulsion efficiencies, combustion stability, and reduced emissions. BENEFIT: It is anticipated that the successful completion of the Phase I, and Phase II programs will result in a functional prototype imaging instruments that can be used for spray formation in dense spray characterization. The Phase I effort will help establish the feasibility of developing an advanced and innovative multi-angular illumination, multi-angular imaging approach.
