Abstract
Form and structure of turbulent flames is decisively determined by the interaction between turbulent flow field and flame reaction. For direct experimental investigation of these processes a simultaneous non-intrusive measurement of the local resolved velocity and temperature field is necessary. So far with particle image velocimetry (PIV) the two-dimensional (2D) flow field and with laser Rayleigh scattering techniques (LRS) the 2D-temperature structure can be measured only separately, since scattering from particles necessary for PIV-techniques excludes the application of conventional Rayleigh scattering thermometry. Now the recently developed filtered Rayleigh scattering thermometry (FRS thermometry) enables a combined simultaneous and locally resolved measurement of the planar gas velocity and temperature field. With first measurements in a turbulent V-flame the possibility of a correlated determination of local flow and flame parameters is shown, which could not be obtained from existing measurement techniques.
