Multi-scalar and velocity measurements in a turbulent bluff-body flame using spectral fitting of Spontaneous Raman Scattering and PIV
Résumé
The objective of this study is to experimentally investigate the complex shear and mixing layers of the recirculation zone at the exit of a canonical bluff-body burner by spontaneous Raman scattering and PIV, in order to have a deeper understanding of combustion mechanisms that lead to the stabilization of the flame. Temperature and multi-species number density profiles across the recirculation zone of the bluff-body burner are compared with velocity fields measured by PIV and flame imaging to identify the specific features of the flame in the recirculation zone consisting in eddies of partially burnt gas and a diffusion flame of CO close to the annular air flow.
