Abstract

By being a function of both transport (diffusion) and chemical reaction rates, the laminar burning velocity (LBV) of a gaseous fuel/oxidant mixture is a window to the complexities of combustion. Direct photography of the inner cone of a Bunsen flame remains a classical measurement technique for estimating LBVs. The availability and utility of the modern digital camera, together with the ease and power of digital photograph computer processing, greatly facilitate the determination of LBVs, especially for the undergraduate laboratory. In this work, the LBVs of hydrocarbon/air mixtures are estimated using direct digital photography. In addition, selected flames doped with ammonia are studied. The estimated precision of this technique illustrates the need for careful measurements.
