Spray or aerosol detonation is a topic of keen interest to the hazard prevention and military R&D communities. Spray detonation is also potentially relevant to the study of pulse detonation engines (PDEs) and other hypersonic propulsion systems exploiting detonative combustion. The early work on spray detonation (i.e., circa 1980 or before) has been well documented in review papers by Dabora and Weinberger [50], Nettleton [108], Borisov and Gelfand [21], Sichel [123], and Dabora [49]. The recent review by Kailasanath [70] puts this early work into perspective and summarizes the key issues for spray detonations in PDE tubes. Almost all of the early work involved spray detonations in confined tubes and chambers. Fuel-oxygen mixtures were typically used, although air was employed as the oxidizer in some studies. A brief summary of highlights is presented in Sect. 1.2. The main focus of spray detonation studies during the 1980s and into the mid-1990s was on the determination of detonability limits for unconfined fuel sprays in air for a variety of industrial chemicals and motor fuels. However, these studies are few in number and very little follow-on work has been reported during the past decade. A review of this work is provided in Sect. 1.3. Another topic of keen interest during the period from the mid-1970s to the late 1980s was so-called chemical or non-explosive initiation of detonation. The goal of this work was to replace the cloud initiator charges in conventional fuel-ai
