Chemical Species Identification in Otto Fuel Combustion
Abstract
Chemical Species Identification in Otto Fuel CombustionAbstract: Increasing the combustion efficiency of undersea propulsion syste"ms is greatly aided bycomputer models that can accurately predict the thermal decomposition kinetics of propellants.However, the c"hemical kinetic mechanisms within these computer models must first be validatedagainst experimental data under well-defined conditi"ons. Presently, there is a severe lack ofexperimental data for propellants against which the mechanisms can be validated. The propo""sedresearch will provide these missing data. Specifically, the research include the design,construction, and implementation of a h""igh-pressure flow reactor, which will be used to identifyand quantify reactive intermediates in the thermal decomposition of naval"" propellants. Thequantification will be performed using ex situ gas analytics via gas chromatography, massspectrometry, and therma"l conductivity under application relevant conditions. These techniqueswill be complemented by in situ spectroscopic techniques with" collaborators at Montana StateUniversity. The initial experimental targets will be nitromethane, iso-propyl-nitrate, and npropyl-""nitrate. In addition, work performed under this proposal is to develop technology for bothmilitary and civil application.
