The Laminar Burning Velocity of Isooctane, N-Heptane, Methanol, Methane, and Propane at Elevated Temperature and Pressures in the Presence of a Diluent

A constant volume bomb was used to determine basic combustion characteristics of isooctane, n-heptane, methanol, propane and methane. Results show that the laminar flame velocity of a quiescent homogeneous air/fuel mixture can be derived from pressure-time data in the bomb. The effects of pressure, temperature, and charge dilution on flame velocity and ignition are presented. A thermo-chemical kinetic model accurately predicted concentrations of nitric oxide during combustion and in the burned gas.
