Studies in Flame Propagation and Blowout
Abstract
This report outlines our most recent research work on the topic of upstream flame propagation and blowout in hydrocarbon jet flames. Outlined specifically are the recent elements of the research for the study of fundamental structural characteristics of jet flames and related flame/spray/flow interactions. Specifically, the scope encompasses further optical imaging investigations of flame structure and behavior, and an exploratory study of the effects of co-flow air on extinction and blowout. Analysis of the results of experiments to understand the behavior of gaseous and spray flame counterparts is the main deliverable. The methodology of the research is largely experimental, emphasizing the application of optical diagnostic techniques to instantaneously visualize reaction zones. The main efforts to report since the last update are the following: 1) Studies have been launched that examine the development of combustion in an initially non-reacting methane jet after ignition at a downstream location and 2) The driving mechanisms that cause jet-flame blowout, particularly in the presence of air co-flow, have been investigated. This work attempts to determine the role of fuel velocity and air co-flow in the blowout phenomenon.
