“…Neelamani, Bhaskar, and Vijayalakshmi (2002) experimentally analyzed the wave force on a horizontal composite structure consisting of a perforated square caisson encircling a circular vertical cylinder and proposed a simplified calculation method for evaluating the wave forces. Guo et al (2011) experimentally studied the hydrodynamic properties of the twin-layer breakwater, and their results indicated that appropriate arrangement of such breakwaters would yield good characteristics in dissipating waves.…”

Using the methods of variable separation and eigenfunction expansion for velocity potentials, an analytical expression for the composite structure of a submerged cylinder over a coaxial, bottom-mounted cylinder in finite depth is developed. This model is also applicable for the isolated submerged truncated cylinder by careful choice of bottom cylinder height. The exciting forces on the submerged cylinder obtained by the proposed analytical solution and the boundary element method (BEM) agree well with each other, which shows good reliability of the analytical expression. Based on the proposed model, the effects of wave force on submerged cylinder owing to the existence of topographical obstacles of different sizes are investigated. The results show that various geometrical parameters of the bottom cylinder alter wave force on the upper cylinder significantly. Considering the impact of barrier, horizontal wave force and vertical wave force on submerged cylinder arrive there are several peaks at different frequencies, while the isolated cylinder always reaches the peak at a certain frequency. The peak value of wave forces may increase or decrease, but that of overturning moment has a maximum value of two to four times amplitude.

“…Liang compared the bubble data in the prototype and models of the middle chamber of Xiaolangdi Project, which shows that the bubble whose diameter is greater than 2 mm in prototype agrees to the gravity similarity law and can be simulated in the models [4]. Wang carried out three model tests with various wave periods to study the performances of air bubbles breakwater in the State Key Laboratory of Coastal and Offshore Engineering [5,6].…”

The numerical simulation of air bubbles breakwater was presented in this paper. The two-phase fluid of water and air was assumed as a variable density fluid. The numerical models were developed by FLUENT in order to explore the air amount scale in the system of air bubbles breakwater . The continuity equation, the Reynolds average equations and the standard k-e equations were selected as the governing equations and the interface of water and air was traced by the VOF method, the additional mass source was added to the continuity equation by The Macro of UDF. The relationship between the air amount scale and the length scale was obtained, which illuminated that the air amount scale of air bubbles breakwater agrees to the gravity similarity law. Furthermore, the effect of air amount and the incident wave periods on the performance of the air bubbles breakwater was analyzed.
