Hydrodynamic Pressures Acting upon Hinged‐Arc Gates
Publication: Journal of Hydraulic Engineering
Volume 111, Issue 4
Abstract
A new method for calculating the mean value of the local hydrodynamic pressure acting upon a hinged gate and a mathematical model of pressure pulsation are developed. The mean hydrodynamic pressure at an optional point on the surface of a hinged gate is obtained by using the Bernoulli equation and model test data. The problem of the pulsation phenomenon of hydrodynamic pressure is solved by considering the random character of the process and by making measurements of pressure fluctuation. Numerical analysis of the results obtained make it possible to determine the autocorrelation function and the power spectral density function and, in consequence, to draw conclusions concerning the character of and reasons for the pulsation phenomenon of the pressure. As a result of the investigations, a normalized power density spectrum equation, which characterized the frequency of the pressure pulsation, is derived.
