- W2021145482 abstract "ABSTRACT The multi-stage control valve is one of the devices which controls cavitation and high pressure drop. To attain the high pressure drop, the conventional control valves adopted the multi-stage trim to avoid the occurrence of local cavitation in valves. This work studied the effect of divergence angle on the characteristics of multi-stage trim. Pressure drop and flow characteristics was calculated for the 1 passage of multi-staged trim by using the FLUENT 6.3.26. The result showed that the pressure drop is significantly influenced by the divergence angle of multi-stage trim. In addition, the pressure drop increased consistently as the Reynolds number and divergence angle increases. † 1. 서 론 고차압 밸브는 과도하게 높은 압력강하에서도 동작할 수 있도록 설계된다. 압력 강하로 인해 생성된 유체의 높은 운동에너지는 공동화 현상(cavitation), 플래싱(flashing), 질식유동(choked flow), 소음 및 진동과 같은 문제를 발생시킨다. 이로 인해 밸브의 주요 부품인 트림(trim), 디스크(disk), 씨트링(seat-ring), 플러그(plug)등에 손상을 유발한다. 그러므로 이상적인 압력강하는 밸브의 트림에 적은 에너지를 흡수시키고 과도한 유속을 발생시키지 않도록 설계되어야 한다. (1) 공동화 현상은 밸브 내의 국부적인 높은 속도로 인한 낮은 압력 영역에 의해 발생되는데, 일반적으로 씨트(Seat) 지역이나 밸브 개구부(vena contracta), 하류부(down-stream)와 같은 대상 지역에서 발생하게 된다. 이와 같은 문제점들을 해결하기 위해서 선진국에서는 1980년대 초부터 유로 면적의 변화 없이 압력 손실을 유도하는 미로형 밸브(labyrinth type valve)를 연구하였으며, Rahmeyer 등" @default.
