Abstract

Propagation characteristics of premixed laminar iso-octane flames at atmosphere and equivalence ratios from 0.8 to 1.4 are studied in a constant combustion bomb using a schlieren technique, the laminar burning velocity at different initial pressure, temperature, equivalence ratio are calculated through CHEMKIN program. The experimental and calculation results show that the laminar burning velocity of iso-octane rise with the decreasing of initial pressure and rise with the rising of initial temperature . Only changing the initial temperature or pressure ,the maximum laminar burning velocity of iso-octane were both obtained at equivalence ratio 1.1. Flame stability become weak ,when increased the equivalence ratio. The problem of the chemistry reaction mechanism to predict the laminar burning velocity were analysed.
