Governmental mandates are set to increase the production and utilization of biofuels, restrict the emissions of greenhouse gases and pollutants, and increase combustor efficiency. As a result, the computer-aided design of advanced combustors will require well-characterized, detailed chemical models as a foundation. In the first part of this talk he will present results from a comprehensive experimental and kinetic modeling study of C3 and C4 aldehydes. Aldehydes are carcinogenic compounds linked to the use of biofuels. Experiments were conducted in a jet stirred reactor and in counterflow flames and were then used to develop and validate a detailed chemical kinetic model for the aldehydes. He will highlight some of the controlling reaction pathways responsible for the extensive cool flame or low-temperature reactivity observed during the oxidation of the aldehydes. The second part of this talk will discuss ongoing research into the minimization of uncertainties associated with predictions of fundamental flame properties. In this work, a large set of laminar flame speed data was systematically collect for the C1-C4 hydrocarbons and USC Mech II was used as a sample model. The method of uncertainty minimization using polynomial chaos expansions was employed to constrain the model uncertainty in flame speed predictions. The goal of this work will be to eventually answer the questions concerning the type of hydrocarbon fuels that have the greatest impact on model uncertainty reduction, and the accuracy needed in flame measurements to better facilitate model development. Finally, he will briefly discuss the surrogate fuel methodology developed at Princeton University for describing petroleum-derived fuel kinetic properties.
