Abstract
A concurrent-flow thin-liquid layer is placed over the intersecting-flow in diamond-shaped column bundles to compose a hybrid assembly in the present work. Flow visualization study is performed to observe streamlines around diamond-shaped cylinders by means of fluorescent dye illuminated with a laser light sheet. A laser Doppler velocimetry(LDV) is employed to determine the variations of velocity distribution and Reynolds stress on the horizontal and vertical sections around the concurrent-flow thin-liquid layer over the intersecting-flow. The concurrent-flow interaction of the thin-liquid sheet and the intersecting-flow is disclosed in diamod-shaped column bundles.
