Abstract

The pipping system is widely used in many industries as equipment for transporting fluids over long distances. In high-pressure pipe, as the speed of the fluid increases, a loud noise is generated. Therefore, various studies have been conducted to reduce pipe noise. In this paper, a pipe noise analysis was developed to predict and quantitatively assess the flow-induced vibration and acoustic-induced vibration due to valve flow in high-temperature and high-pressure. To do this, a high-fidelity fluid analysis technique was developed for predicting internal flow in the pipe with valve. In additional, the contribution of compressible/incompressible pressure by frequency band was evaluated using the wavenumber-frequency analysis. To predict a low/middle frequency pipe noise, the vibroacoustic analysis method was developed based on Finite Element Method (FEM). And the pipe noise prediction method for the middle/high frequency was developed based on Statistical Energy Analysis (SEA).

배관시스템은 유체를 장거리로 이송시키는 장비로서 많은 산업군에서 사용되고 있다. 고압의 배관에서는 빠른 유속으로 인하여 소음이 크게 발생하고 있으며, 이러한 소음을 저감 시키기 위한 많은 연구가 수행되고 있다. 이 논문에서는 고온․고압의 배관내 밸브 유동을 원인으로 발생하는 유동유발진동과 음향유발진동을 설계단계에서 예측하고 정량적으로 분석을 위한 배관 소음 해석 기법을 개발하였다. 이를 위하여 배관의 내부 유동 예측을 위한 고정밀 유동 해석기법을 개발하였으며, 파수-주파수 분석법을 이용하여 주파수 대역별 압축성/비압축성 압력의 기여도를 평가하였다. 그리고 유한요소 해석법(Finite Element Method, FEM)을 기반으로 한 저․중 주파수 대역의 진동소음 해석기법을 개발하였으며, 통계적 에너지 분석법(Statistical Energy Analysis, SEA)을 기반으로 한 중․고 주파수 대역에서의 방사소음해석 기법을 개발하였다.
