Three-dimensional gradients of the hydroxyl radical (OH) concentration were measured in a premixed, lean natural gas / air flame by simultaneous laser induced fluorescence imaging (LIF) in a crossed-light-sheet configuration and one-dimensionally resolved Raman scattering. The technique is applied to measurements in a turbulent bluff-body flame with the aim to investigate correlations between species concentration gradients and local concentrations.
