Abstract
A concurrent-flow thin-liquid layer is placed over the intersecting-flow jet to compose a hybrid assembly in the present work. Flow visualization study is performed to disclose flow pattern using high-porous, polymer particles and to observe streamlines at the jet interface by means of fluorescent dye illuminated with a laser light sheet. A laser Doppler velocimetry(LDV) is employed to determine the timewise variation of velocity distribution and its variation, turbulence strength, and Reynolds stress near the jet interface. Characteristics of the interaction of thin-liquid sheet with concurrent intersecting-flow are disclosed.
