| Popis: | Fundamental research of turbulent combustion often requires the unambiguous localization of flame front positions and structures. Laser-induced fluorescence (LIF) imaging provides different possibilities of detecting two-dimensional distributions of species typical for reactive areas. Simultaneous measurements of hydroxyl and formaldehyde laser-induced fluorescence and total number densities by Rayleigh scattering were carried out in a Bunsen type flame, which yields state of the art but noisy images. Nonlinear anisotropic diffusion of edge-enhancing type [1] is shown here to enhance the capabilities of the laser-imaging technique in terms of flame front localization and correlation analysis. |
