Laminar Burning Speed Measurements of Indolene-Air-Diluent Mixtures at High Pressures and Temperatures 850047
The laminar burning speeds of two practical multi-component hydrocarbon fuels similar to automotive gasoline were measured using a spherical combustion bomb with central ignition. Mixtures with equivalence ratios between 0.7 and 1.6, and volume fractions of simulated residual gas between 0 and 0.3 were tested at pressures from 0.4 atm to 12 atm and unburned gas temperatures from 350 K to 550 K. The laminar burning speeds were fitted to a power function expression involving the unburned gas pressure and temperature, and the diluent fraction.
The pressure and temperature dependences of the laminar burning speed for undiluted mixtures agreed well with values reported by other investigators for various fuels, indicating that these dependences are independent of fuel type. The percentage reduction in laminar burning speed due to the addition of simulated residual gas was found to be a function only of the amount added, independent of the properties of the mixture.
