NUMERICAL ANALYSIS ON THE REFLECTION COEFFICIENT OF A CURTAIN BREAKWATER USING OPENFOAM

摘要：

　　This paper presents a two-dimensional numerical investigation on the reflection coefficient of a curtain breakwater including a seaside drooping plate and a leeside caisson.A numerical wave flume is developed based on the continuity equation and the Navier-Stokes equation where the VOF method is used to track and locate the free surface.Relaxation zone method is used to implement the generation and absorption of waves.The numerical results of the reflection coefficient for the curtain breakwater are in good agreement with experimental data in literature.The variations of the reflection coefficient versus factors of the wavelength,the wave chamber width,the immersed depth of the drooping plate and the angle at the bottom of the drooping plate are examined.It is found that for reaching lower reflection,the values of the wave chamber width should be around one tenth of the wavelength.The incident wave energy is dissipated by the vortex flows around the drooping plate effectively.The present numerical wave flume based on OpenFOAM can well estimate the hydrodynamic performance of the curtain breakwater for practical application.
