合・分流角度の異なる交差管内の流れの可視化に関する研究

抄録

Authors have disclosed the mechanics and correlations of the flow phenomena in two intersecting ducts with the same angles of confluent and branching flows. In this study, experiments in two intersecting ducts with different confluent and branching angles are performed to investigate the vortex formation in the intersecting ducts. Also it investigates the flow rates in the left and right ducts when changing the condition of the upper water levels. The flow pattern in the intersecting ducts is visualized by the particle tracing method using ion exchange resin. The distribution in the intersecting region is measured by the LDV method. The flow characteristics are clarified in the intersecting ducts with different confluent and branching angles. It is also 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.
