Title

Laser Ignition And Burning Velocity Measurements In Natural Gas/Air Mixtures

Abstract

The laminar burning velocities of methane/air have been obtained using UCF's high-pressure combustion bomb facility. High-speed schlieren photography is utilized to present the flame development propagation in select cases. Additionally, the flammability limits of methane-air mixtures are studied following ignition using Nd;YAG laser at 1064nm. Pressure traces and flame images are presented near the flammability limits. The laminar burning velocity of methane-air mixture is determined for initial temperature of 25 and 120 C, equivalence ratio range 0.7-1.4 and an initial pressure of 1 and 3 bar. The results of methane-air mixture study are compared with the laminar burning velocity measurements in the literature and the values predicted by two existing kinetic mechanisms. Current experiments are in very good agreement with existing literature data and the numerical model predictions.
