摘要：

Wall pressure fluctuation is one of the source terms which result in the vibration of hydraulic structures. To consider both the space and time correlation of the pressure field, the method of proper orthogonal decomposition and low-dimensional approximation were used here to describe the pressure signals of the turbulent boundary layer, the apron of the stilling pond and the vertically impinging jet.
