| Research Abstract |
Measurements of laminar burning velocities for CH_4/O_2/H_2O premixed flames were conducted underfuel-rich and high-pressure conditions using a Bunsen-type flame. Experimental data of laminar burning velocities were compared with numerical results calculated using detailed chemical reaction mechanisms, and the verification for the feasibility of the reaction mechanisms was performed under specific conditions such as high equivalence ratio, high pressure, and high steam dilution. Sensitivity analysis and reaction pathway analysis were also conducted, and the effects of steam dilution and fuel-rich conditions on chemical reactions for CH_4 oxidation were investigated.
