Abstract

Abstract

On the basis of linear potential theory,an analytical study on the hydrodynamic performance of a submerged breakwater is given in front of a partially reflecting sidewall.The calculating method of the transmission and reflection coefficients of the submerged breakwater is developed by using the matched eigenfunction expansion method.The calculated results of the transmission and reflection coefficients agree very well with those by the boundary element method.The main effect factors of the transmission and reflection coefficients of the breakwater are analyzed.The transmission coefficient of the submerged breakwater increases with the increasing reflection coefficient of the partially reflecting sidewall.With the increasing value of the relative breakwater width or the relative space between the breakwater and the sidewall,both the transmission coefficient and the reflection coefficient of the breakwater vary periodically.But the variations of the reflection and transmission coefficients are just the opposite.
