Title: Two-dimensional bunsen flame
Description: The image shows a two-dimensional Bunsen flame using methane at equivalence ratio of phi = 1.2. Blue flame luminosity due to emission from CH and C2 radicals, green particle tracks due to scattering from MgO particles under 6kHz excitation of a Cu-Vapor laser. FUJI 1600 ASA film.
