| Zusammenfassung | Different experimental strategies for quantitative measurements of mixing fields at transient free gas jets by means of laser-induced fluorescence are discussed. Important issues like the selection of fluorescence markers, seeding strategy, fluorescence quenching, correction of spatial and temporal variations in the laser-illumination field, and the conversion from raw signals to absolute mixture fraction values are discussed. As an alternative to conventional LIF-tracer seeding strategies, a hybrid method combining jet seeding and inverse (ambience) seeding is applied found to provide a straightforward laser-sheet correction and signal calibration. |
