Notes:
Abstract Laser-Induced Fluorescence is used to tomographically produce volume information of concentration distribution in a turbulent shear flow. Based on Adaptive Least Squares Correlation (ALSC) of grey level distributions in small patches cut out of consecutive tomographically constructed observation volumes, 3-D fields of velocity, vorticity and rate-of-strain are determined with high spatial resolution, satisfactory temporal resolution and high accuracy. This novel technique opens new perspectives for the study of mixing processes.
