Abstract

A sudden pressure drop caused by the pressure relief valve acts as a strong noise source and propagates the compressible pressure fluctuation along the pipe wall, which becomes a excitation source of Acoustic Induced Vibration (AIV). Therefore, in this study, the numerical methodology is developed to evaluate the reduction effect of compressible pressure fluctuation due to curved pipe in the pressure relief valve system. To describe the acoustic wave caused by density fluctuation, unsteady compressible Large Eddy Simulation (LES) technique, which is high accuracy numerical method, Smagorinsky-Lilly subgrid scale model is applied. Wavenumber-frequency analysis is performed to extract the compressible pressure fluctuation component, which is propagated along the pipe, from the flow field, and it is based on the wall pressure on the upstream and downstream pipe from the curved pipe. It is shown that the plane wave and the 1st mode component in radial direction are dominant along the downstream direction, and the overall acoustic power was reduced by 3 dB through the curved pipe. From these results, the noise reduction effect caused by curved pipe is confirmed.

감압밸브에서 발생하는 급격한 압력저하는 강한 소음원으로 작용하여 배관을 따라 압축성 압력섭동을 전파시키며, 이는 음향유기진동의 가진원으로 작용한다. 따라서 본 연구에서는 감압밸브가 있는 배관 시스템에서 곡관에 의한 압축성 압력섭동의 저감 효과를 확인할 수 있는 수치기법을 개발하였다. 배관 내 밀도 변화에 의한 음향파 성분을 모사하기 위해 고정밀 해석기법인 비정상 압축성 대와류모사 기법을 적용하였으며, 아격자 모델로는 Smagorinsky-Lilly 모델을 적용하였다. 배관을 따라 전파되는 압축성 압력섭동 성분을 유동장 정보로부터 추출하기 위하여 파수-주파수 분석을 수행하였으며, 곡관을 기준으로 상류방향 배관과 하류방향 배관의 벽면 압력을 활용하였다. 이를 통해 평면파 성분과 n=1에 해당하는 모드 성분이 하류 방향을 따라 강하게 나타나는 것을 확인하였으며, 곡관을 전후로 전체 음향파워가 3 dB 저감되는 것을 확인함으로써 곡관에 의한 압축성 압력섭동 저감 효과를 확인하였다.
