Experimental and Kinetic Modeling Study of Laminar Burning Velocities of Cyclopentanone and Its Binary Mixtures with Ethanol and n-Propanol

摘要: Cyclopentanone is a promising biofuel that can enable more efficient engine operation and increase the fuel economy of light duty fleet over current planned technology developments. While ignition cyclopentanone has been investigated in detail, studies on laminar burning velocities are called for. In this work, (C5H8O) have measured using heat flux spherical flame methods at 1 atm, equivalence ratios from 0.7 to 1.6, initial temperatures 328, 353, 428 K. To further investigate relationship between molecular structure velocity, identical experiments were also performed for binary mixtures with ethanol n-propanol 1:1 (mol). The consistency experimental data sets obtained work literature evaluated. A recently published mechanism was used simulation after adopting submechanism n-propanol. Good agreement seen simulated results all flames. qualitatively explain characteristics velocity differences those n-propanol, sensitivity analysis reaction pathway compare chemistry fuels under conditions, which revealed how could affect its velocity. Compared does not primary carbon atoms molecule, leading lower production methyl radicals. Meanwhile, carbonyl group molecule mostly released as CO decomposition multiple intermediates accompanied by unsaturated C2 C4 species, especially C2H4 C2H3. Both features contribute high cyclopentanone. (Less)
