Abstract
Experiments are performed to investigate the vortex formation in and near the intersecting region by the particle tracing method using the ion exchange resin. Both the symmetric and asymmetric flows in two intersecting ducts with the different confluent and branching angles are also investigated. It is disclosed that the fluid control in the intersecting ducts with the confluent angle of 60° and the branching angle of 30°is easier than those with other angles.
