Flame Velocimetry Measurements of Inhibited Methane/Oxygen Flames Using Pulsed Flame Velocimetry

摘要

Knowledge of flame velocities is an important factor in the design and construction of many devices involving combustion phenomena. We report here results of flame velocity measurements obtained using pulsed flame velocimetry, a new technique that may be useful for Halon replacement research. 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 velocimetry as a predictive technique for inhibitor efficiency studies is discussed.
