제트유동에 의한 튜우브 집합체의 진동 연구
Jet-Flow-Induced Vibration of Tube Arrays
- 발행 : 1986.01.01
초록
본 논문에서는 제트유동에 놓인 튜우브 집합체의 진동 발생구조를 깊이 파악하고 일반성 있게 사용할 수 있는 설계 지침을 마련하기 위하여 보다 광법위 하게 수행된 파라미터 연구 내용을 다루었다
This paper presents a study on jet-flow-induced vibration, which has been one of the main causes of fuel damage in many pressurized water reactors. A systematic investigation was carried out experimently to identify the mechanism of jet-flow-induced vibration and to provide a design guide. Fluidelastic instability occurs when the jet velocity exceeds a critical value. The threshold of instability is given by V/f
