Abstract : The major portion of the research briefly described in this report involved the use of methods of mathematical analysis and computer simulations to elucidate behavioral features of open combustion processes, particularly transient characteristics. Mathematical models of various types of systems were studied, including well-mixed combustors, diffusion flames, surface reactions, and reacting boundary-layer flows. Principal results include the discovery of instabilities and other transient characteristics, not previously recognized, which are important in the prediction and understanding of ignition and extinction phenomena. Situations in which instabilities lead to sustained oscillations were also studied, and some comparisons of results of laboratory experiments with theoretical predictions for a premixed combustible mixture in stagnation flow were possible.
