Abstract
The flow in the intersecting region in which confluent and branching flows exit continuously is complex due to combined consequence of the ramming phenomena and the centrifugal force. In this study, both the symmetric and asymmetric flows in the intersecting region are investigated by the methods using elastic pole and LDV. The intersecting angle and flow rates are varied to determine their effects on flow behavior. The mechanisms of secondary flow generated downstream in the intersecting region are disclosed.
