Tomographic reconstruction of 2D-OH∗-chemiluminescence distributions in turbulent diffusion flames

Abstract

A recently developed fast tomographic reconstruction device (Anikin et al. in Appl. Phys. B 100:675, 2010) has been applied to detect 2-D chemiluminescence distributions of OH∗ in reaction zones of a near laminar and a turbulent diffusion flame. A series of single-shot experiments has been carried out in both flames offering cold gas flow velocities of 0.43 m/s and 4 m/s and flame diameters up to 60 mm, respectively.
