Gravity wave interaction with a composite pile-rock breakwater
Abstract Surface gravity wave interaction with a novel composite pile-rock breakwater having a stack of porous plates fixed on its top is investigated in the present study. A novel numerical code based on dual-boundary-element-method is developed to understand the wave scattering and force coefficients within framework of linearized potential flow theory. Out of the four different proposed configurations (pile-rock alone, vertical, horizontal, and H-shaped porous plate assembly with pile-rock), it is found that a novel H-shaped porous plates with submerged pile-rock are very effective in attenuating the wave energy. The parametric study for the H-shaped configuration with several key aspects like porosity of the permeable plates, submergence depth of the horizontal plate, pile-rock relative height and width of the pile-rock barriers are investigated. Increasing relative rock barrier width from 0.25-0.75 offers only a marginal reduction in wave transmission but increases the vertical wave force on the H-plate barrier almost twice. By changing relative submergence of the horizontal porous plate from, it is possible to reduce wave transmission by about 10% but at the expense of increasing vertical wave force almost 50%-75%. Increasing the pile-rock height helps to reduce the wave transmission but significantly increases horizontal wave force and moment on perforated H-shaped barrier. The results of the parametric study can be used for optimizing the dimensions of pile-rock cum porous plate wave barrier for a wide range of field conditions.
期刊介绍:
The Journal of Offshore Mechanics and Arctic Engineering is an international resource for original peer-reviewed research that advances the state of knowledge on all aspects of analysis, design, and technology development in ocean, offshore, arctic, and related fields. Its main goals are to provide a forum for timely and in-depth exchanges of scientific and technical information among researchers and engineers. It emphasizes fundamental research and development studies as well as review articles that offer either retrospective perspectives on well-established topics or exposures to innovative or novel developments. Case histories are not encouraged. The journal also documents significant developments in related fields and major accomplishments of renowned scientists by programming themed issues to record such events.
