비정상류가 흐르는 파이프의 스펙트럴 요소 동역학 해석
SPECTRAL ELEMENT DYNAMIC ANALYSIS OF THE PIPELINE CONVEYING INTERNAL UNSTEADY FLOW
- 발행 : 2005.11.01
초록
In this paper, a spectral element model is developed for the uniform straight pipelines conveying internal unsteady fluid. The spectral element matrix is formulated by using the exact frequency-domain solutions of the pipe-dynamics equations. The spectral element dynamic analyses are then conducted to evaluate the accuracy of the present spectral element model and to investigate the vibration characteristics and internal fluid transients of an example pipeline system.
