유입수문이 펌프장 흡수정 내 볼텍스 발생에 미치는 영향

In pumping stations, vortex generation such as free surface vortex and submerged vortex occurring near the pump intake, or at bell-mouth inlet has been an important flow characteristic which should be considered always to keep away the suction of air-entertained or cavitated flow. These problems are caused by unfavorable approach flow patterns at suction inlet that are subjected to sump configurations and operation conditions. In this research, the sump model test with gated inlet was mainly undertaken to observe the trend of vortex generation in the representative models, which were selected in the field survey of Kwater's Pump Sump. With experimental Result, the guidelines for pump sump with gated inlet are presented in this paper.
