Species imaging in spray flames

Not Accessible

Abstract

The complicated interactions between an evaporating fuel spray and a reacting turbulent flow field pose a considerable challenge for combustion modelers and experimentalists. Two-dimensional imaging of critical species concentrations, a technique developed previously in connection with homogeneous reacting systems, offers the potential for illuminating such interactions. We report here on our work to extend this technique to spray flames using planar laser-induced fluorescence monitoring of OH and CH as well as planar multiphoton dissociation of fuel vapor and pyrolysis products.
