Diagnostics and control of large-scale structures in swirling premixed flames

Abstract

The present work is devoted to the experimental study of the flow structure of premixed swirling jet flames at various combustion regimes. A stereo PIV technique combined with a pressure probe was used for the investigation of the role of large-scale vortices in turbulent structure of the flames. Instantaneous velocity and vorticity fields were estimated, as well as the spatial distributions of the mean velocity and turbulent kinetic energy components. To determine a shape and location of the flame front, chemiluminescence images captured by an ICCD camera were used. The analysis of the results is aimed for the efficiency of active (by applying an acoustic forcing) and passive (by introducing a swirl) ways to control properties of large-scale vortices strongly affecting the combustion in turbulent flame.
