Abstract
This research investigates water-wave scattering via a horizontal perforated plate fixed at the still water level through analytical studies and physical model tests. The velocity potential decomposition method is combined with an efficient iterative algorithm to develop an analytical solution in which the quadratic pressure drop condition is imposed on the horizontal perforated plate. The analytical results are in good agreement with the results of an independently developed iterative boundary element method (BEM) solution. Experimental tests are carried out in a wave flume to measure the reflection coefficient and transmission coefficient of the horizontal perforated plate, and the analytical results agree reasonably well with the experimental data. The influence of various structural parameters of the horizontal perforated plate on the hydrodynamic parameters of reflection coefficient, transmission coefficient, energy-loss coefficient, and wave force are analyzed on the basis of the analytical solution. Useful results for the practical engineering application of horizontal perforated plates are also presented.
