TL;DR: In this paper, simulations carried out to simulate wave transformation along the flume following the initial beach profile and the wave conditions given in Roelvink(1993) were compared.
Abstract: This note reports simulations carried out to simulate wave transformation along the flume following the initial beach profile and the wave conditions given in Roelvink(1993). Parametric spectral and wave-by-wave approaches are compared. An estimation of the distribution of the skewness of the bottom orbital velocity along the flume is also given.

TL;DR: In this paper, a smoothed particle hydrodynamics model for simulating wave-induced rotations of a bottom-hinged flapper was established in a 2D numerical wave flume.
Abstract: In this study, a Smoothed Particle Hydrodynamics model for simulating wave-induced rotations of a bottom-hinged flapper was established in a 2-D numerical wave flume. The simulated rotating angles illustrated that the flapper could swing back and forth following harmonic wave loadings. The simulations were also seen to be in good agreement with experimental data, confirming the applicability of the present numerical model. The simulated hydrodynamic behaviors at different phases showed that the flapper moved downstream under the wave crest and upstream under the wave trough following the elliptical form of water particle trajectory. The energy conversions of a flapper during an average wave cycle showed that larger rotating angle ranges could result in higher energy conversions. However, smaller rotating angle ranges could result in higher captured efficiency.

TL;DR: In this article, the results of a flume experiment and a theoretical study of surface wave motion over a fluidized bed are presented, and it is shown that a resonant wave interaction between a surface wave and two interfacial waves at the interface of the fresh water and the fluidised bed is a strong mechanism for instability of the interface and the subsequent mixing of the layers.
Abstract: The results of a flume experiment and a theoretical study of surface wave motion over a fluidized bed are presented. It is shown that a resonant wave interaction between a surface wave and two interfacial waves at the interface of the fresh water and the fluidized bed is a strong mechanism for instability of the interface and the subsequent mixing of the layers. The interfacial waves are subharmonic to the surface wave and form a standing wave at the interface. The interaction is investigated theoretically using a viscous interaction analysis. It is shown that surface wave height and viscous effects are the determining factors in the instability mechanism. The results indicate that the net effect of viscosity on the interaction is to suppress the interfacial waves.
