Absorption Wave Theory

As a better kind of modeling technology, absorbing wave-maker can solve the problemof multi-reflective waves in hydraulic laboratory, thus improve the precision of hydraulicexperiment when model is used to resolve the problems of harbor, offshore and coastal. engineering. This paper mainly discuss the application of the theory of absorbingwave-maker.On the basis of some achievements relative to absorbing wave-maker which were made by some experts overseas, the former part of this thesis is mainly focus on the theory of absorbing wave-maker and its practicability in engineering. A new absorbing method of irregular waves, which is called the weighted averaging method of representative frequencies, is proposed in this paper.The analysis and assessment method of the effectiveness of the proposed absorbing wave-maker theory is discussed in the last part of this paper. And several conceptions, such as stability of waves and absorptivity, are given, which made it possible to evaluate the effectiveness of the wave-maker quantificationallyThe result of a series of experiments which using the new method certify that the methods are effective to resolve the problem of multi-reflection in wave flume.
