Abstract
A duct nozzle with an X-shaped flow network has dramatically stabilized a slit liquid flow. This stability has been deduced by the swirl in the boundary region between concurrent thin-liquid layers. The concurrent-flow is the slit flow (thin-liquid layer) that is placed over the intersecting-flow in X-shaped channels. The swirl has been produced by flow oscillations in a right angle to the flow direction caused by the flip-flop phenomena in X-shaped channels. The swirl has absorbed the instability of a slit liquid flow as the energy for a swirling motion. An experimental study was performed to investigate the phenomena of two flows; a slit flow and a flip-flop flow placed over it. An experiment has been performed in two different ducts; a duct with X-shaped channels consisting of large diamond-shaped bundles and a duct with small size X-shaped channels in both sides. The velocity variations in their flow fields were measured using two-dimensional PIV and LDV. This study clarified the characteristics of velocity variations on the horizontal and vertical sections with different depths of their X-shaped channels.
