| Abstract: | In order to provide database for structural fatigue analysis,the properties,also the causes,of the fluctuating pressure environment were analyzed based on the physical flow phenomenon, the stability theory and the theory of turbulence. After analyzing the existing techniques for the prediction of fluctuating pressure, the article concluded that the combination of numerical simulation with the empirical models, which are based on the experiments, is a more effective and more economical method with the advancement of the computer performance and the improvement of the reliability and the accuracy of the numerical technique. |
