The engineering and scientific community ha been searching for the identification of surrogate fuels that can reasonably represent the performance and emissions behavior of jet fuels (e.g. Jet A and JP-8) in engines. Many proposals exist in the literature, but there has been no consensus of opinion. It has been recognized that if the surrogate (or its)components were identified and agreed upon, then the research community could focus their resources on the development of chemical kinetic models for accurage representation of this surrogate. This manuscript reviews the findings and recommendations of a working group created by AFOSR, ARO and NIST to identify a surrogate fuel and or its components. As part of this study, the chemical kinetically limited process within a gas turbine are identified. In addition a palette of compounds is presented from which a surrogate fuel might be constructed. We initially suggested a simplified surrogate composed on n-decane, nbutylcyclohexane and nbutylbenzene and experiments were performed and compared to reactivity data for jet fuels. Results indicate that this mixture is more reactive and difficult to extinguish than typical jet fuels. Some ideas for resolving these issues are discussed. Recommendations for future efforts are provided and a road map for the creation of surrogate fuel kinetics models is proposed.
