(DOE Energy Conversion and Utilization Technology Program: NBS Measurement Technology Project): Quarterly progress report, January-March 1982
Proper understanding of sooting processes will aid in assessing the impact of alternative fuels on hardware durability, combustion and heat transfer efficiency, and the environment. These efforts are in direct support of ECUT projects dealing with open cycle/engine combustion technology, direct heating and conversion, physical processes, and chemical processes. Soot formation entails a number of complex processes that occur within and about the combustion zone. These include hydrocarbon cracking, nucleation, growth, agglomeration and burnout. The importance of free radical processes, the involvement of aromatic and acetylenic intermediates, and the effect of inorganic components on the soot formation processes will be investigated. The effect of physical properties (such as boiling point and viscosity) on the droplet formation, evaporation, combustion and subsequent soot formation processes will also be examined. The effect of flow field parameters on the chemical, as well as physical processes will be studied. Initial studies toward investigation of chemical effects on soot formation are being carried out in laboratory-scale diffusion flames of various configurations. Investigations of physical effects on soot formation are carried out in the NBS experimental furnace. A combination of optical diagnostic techniques are used. 8 refs.
