Tomographic PIV study of lifted flames in turbulent Axisymmetric jets of methane

Abstract : In the present work, the capability of the tomo-PIV technique to measure 3D flow structures in reactive flow is evaluated in a lifted flame configuration. In combustion, two main problems can be encountered: the flame radiation and the imaging of the particle field throughout non-uniform distribution of the refractive index. In order to assess these two points, turbulent lifted flames of methane has been investigated. In that condition, the flame is detached from the burner and is in lifted-flame regime far below the blow-off condition. In this simple configuration, some parts of the methane jet is surrounded by the reaction zones and burned gases, both inducing large variations of the refractive index, which are time dependent. The main objective of this experiment is to compare the tomo-PIV results performed in reactive conditions to those obtained in the same optical arrangement without flame (free jet).
