A-37 流体自身の流れで吸引力を制御する渦室付排水管の研究 : (第3報) 排水管内流れのモデル化による特性予測法の検討
詳細
The accident of engulfing human body in the drain port of swimming pool has happened. So, we have studied new safety drainpipe with vortex chamber in order to free from the danger. The proposed drainpipe can control the suction force with the working of water flow itself without any mechanical equipment. In previous report, the suction force and basic flow properties of the drainpipe were analyzed experimentally. This paper is the 3rd report, and we showed the performance prediction method by the modeling of internal flow.
