| Abstract: | ubmerged jets are usual and important phenomena in hydraulic engineering.In this paper, based on experimental data and the correlation analysis method, the correlation and spectrum characteristics of wall fluctuating pressure by two-dimensional submerged jets are investigated. The formula for transforming the spectral function of point fluctuating pressure to that of area fluctuating pressure is developed. The results are conducive to reveal the mechanism of wall pressure fluctuation, important and essential to evaluate the vibration of structures induced by flows and the stability of apron in stilling basin. |
