Chemical Species Identification in Otto Fuel Combustion
Abstract
Increasing the combustion efficiency of undersea propulsion systems is greatly aided by computer models that can accurately predict, the thermal decomposition kinetics of propellants. However, the chemical kinetic mechanisms within these computer models must first, be validated against experimental data under well-defined conditions. Presently, there is a severe lack of experimental data for pr,opellants against which the mechanisms can be validated. The proposed research will provide these missing data. Specifically, the re,search include the design, construction, and implementation of a high-pressure flow reactor, which will be used to identify and quan,tify reactive intermediates in the thermal decomposition of naval propellants. The quantification will be performed using ex situ ga,s analytics via gas chromatography, mass spectrometry, and thermal conductivity under application relevant conditions. -These techni,ques will be complemented by in situ spectroscopic techniques with collaborators at Montana State University. The initial experiment,al targets will be nitromethane, iso-propyl-nitrate, and n-propyl-nitrate. In addition, work performed under this proposal is Fundam,ental Research, having military and civil application.
