Abstract
An experimental study using Particle Image Velocimetry (PIV) on free jets issuing from sharp edge nozzles having different cross-section geometries is reported: elliptical, square, rectangular and triangular. The mixing efficiency of each nozzle is quantified at large and small scales. In respect to the large scales contribution, the definition of mixedness is used, while for smallscales, the entropy generation concept is employed. These quantities are computed to evaluate the mixing efficiency in the near field and interaction zone (0| File | Dimensione | Formato | |
