摘要：

The goal of this work was to contrast and compare the 2D and 3D flame topography of a turbulent flame. The 2D measurements were obtained using CH-based (methylidyne radical-based) planar laser-induced fluorescence (PLIF), and the 3D measurements were obtained through a tomographic chemiluminescence (TC) technique. Both PLIF and TC were performed simultaneously on a turbulent premixed Bunsen flame. The PLIF measurements were then compared to a cross section of the 3D TC measurements, both to provide a validation to the 3D measurements and also to illustrate the differences in flame structures inferred from the 2D and 3D measurements.
