By using particle image velocimetry techniques, this paper presents new insights on the turbulence structure and time-averaged flows in a rectangular cavity with large aspect ratios. The three cavity aspect ratios (L=D, where L = cavity length, D = cavity depth) used in this study are 9.9, 13.0, and...
