Development Of A Chemical Kinetics Mechanisms For C2HX Ignition In The Presence Of Silane

Abstract

An on-going series of experiments regarding the effect of silane addition on H2, CH4, and C2Hx fuels was extended to develop a chemical kinetics mechanism for the ignition and oxidation of hydrocarbon fuels combined with silane (SiH4). Subsequent experiments were conducted in C2H6/SiH4/O2/Ar mixtures without changing the optical settings so that the relationship between concentration and voltage remained constant. A preliminary model of the CxHy/SiH4 kinetics was assembled from the detailed mechanism of Wang and Laskin as well as that of several silane mechanisms available in the literature. The model assumed that the primary interaction between these fuels takes place among the radicals so that reactions between SiH and C2H6 are neglected. The end result of this work was a model of hydrocarbon combustion with silane addition. Although the model is new and primitive (relative to those for hydrocarbons only), it provided information regarding the reactions and pathways whereby small concentrations of silane (XSiH4 < 10% of fuel) can significantly alter the timing of the combustion process. This is an abstract of a paper presented at the 30th International Symposium on Combustion (Chicago, IL 7/25-30/2004).
