Estimation of Laminar Burning Velocities by Direct Digital Photography

Abstract
A function of both transport (diffusion) and chemical reaction rates, the laminar burning velocity (LBV) of a gaseous fuel/oxidant mixture can be a fairly straightforward way to describe the complexities of combustion. Though subject to some uncertainties, 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. In this work, the LBVs of methane/air and ethylene/air mixtures are estimated using direct digital photography. The values obtained compare well with the classical literature.
