Due to their inherent complexity, turbulent flow characterization is heavily relies on experimental research. A multi-color grid technique was recently proposed by the authors as a novel method for characterizing and measuring three-dimensional flows. In this paper, further improvements of this technique are reported by implementing a new method based on color permutations. Several new advances in the experimental implementation and analysis algorithm are then presented and detailed. Results are presented using color streak images and three-dimensional particle trajectories.enThe copyright for the paper content remains with the author.Fluid Mechanics3DFlow visualizationMulti-colorFlow measurementArticle
