Knowledge of flame velocities in an important factor in the design and construction of many devices involving combustion phenomena. Applications include but are not limited to gun design, fire extinguishment, and internal combustion engines. The authors report here results of flame velocity measurements obtained using pulsed flame velocimetry. The method developed here is based on and is an extension of the pulsed flame photometer detector developed at Tel Aviv University. Flame velocities for burning methane/oxygen mixtures to which a small amount of inhibitant has been added are determined using pulsed flame velocimetry. Results are compared to flame velocities measured for similar mixtures using other techniques. Relative flame velocities for burning methane/oxygen mixtures doped with small amounts of inhibitants are compared with macroscopic properties such as relative peak temperatures and flame inhibition efficiencies. The utility of flame velocities determined using pulsed flame velocimetry as a predictive technique for inhibitor efficiency studies is discussed.
