ネットワーク管路における流況特性

抄録

Experiments in the four intersecting ducts with intersecting angles of 30°and 60° are performed to investigate the vortex formation in the intersecting region and the flow rates at the end of each duct. The flow characteristics in six types of the four intersecting ducts are clarified by using different lengths of intersecting zones. The fluid control in the four intersecting ducts with the intersecting angle of 30° is found to have particular characteris-tics in fluid engineering. Furthermore, the relationship between the Reynolds number and the Strouhal number in the swing of water jet at the end of the multiple intersecting ducts is disclosed by measuring the frequency of the swing and the flow rates at the end of ducts.
