dcterms.abstractIt is important to understand the reaction mechanisms and to identify the products formed during the combustion reaction of energetic particles for the development and performance enhancement of hydrocarbon and solid rocket fuels. The utilization of an ultrasonic levitator is of advantage in studying reaction mechanisms considering the experimental advantages of controlling the atmosphere, in avoiding contact surfaces, and in allowing for the study of individual, levitated particles. In this thesis, the decomposition and ignition of two energetic materials, aluminum iodate hexahydrate (AIH) and boron-based hydroxyl-terminated polybutadiene (B/HTPB), are studied utilizing complementary in situ spectroscopic techniques including Raman and infrared spectroscopy, temporally-resolved high-speed optical and infrared imaging, and ultraviolet-visible (UV-Vis) spectroscopy. These studies comprehensively outline the mechanistic details for energy liberation by identifying pivotal reaction steps. Key results highlight the release of oxidizer, the discovery of critical reactive intermediates, and the catalytic role that helps in driving the combustion reactions.
