Experiments and Reaction Models of Fundamental Combustion Properties
Abstract
Experimental, theoretical, and computational studies of various combustion phenomena were carried out for a wide range of conditions. Flames of H2, CO, as well as neat and mixtures of gaseous and liquid hydrocarbons, were studied experimentally. The experimental data were used as the basis for developing and validating reaction and molecular transport models. The following tasks were completed: (1) development of a non-linear extrapolation technique for the determination of laminar flame speeds; (2) quantification of diffusion and kinetics effects on flame propagation and extinction in liquid hydrocarbon flames; (3) quantification of the effect of fuel blending on the flame response; (4) derivation of an extensive experimental flame database for C5-C12 n-alkane, cyclohexane, and alkylated cyclohexane flames; (5) fundamental kinetic studies of elementary reactions; (6) refinement of USC Mech II to predict H2/CO combustion at pressures up to 500 atm; (7) development of detailed and simplified models for the oxidation of C5-C12 n-alkanes; (8) development of the method of uncertainty minimization by polynomial chaos expansion; and (9) gas-kinetic theory analysis of scattering between gas and molecular clusters with application in molecular transport properties.
