Characteristics of Breaking Wave Forces on Piles over a Permeable Seabed
نویسندگان
چکیده
Most offshore wind turbines are installed in shallow water and exposed to breaking waves. Previous numerical studies focusing on wave forces generally ignored the seabed permeability. In this paper, a model based Volume-Averaged Reynolds Averaged Navier–Stokes equations (VARANS) is employed reveal process of solitary interacting with rigid pile over permeable slope. Through applying Forchheimer saturated drag equation, effects permeability fluid motions simulated. The reliability present verified by comparisons between experimentally obtained data results. Further, 190 cases simulated different parameters studied systematically. Results indicate that seabed, maximum can occur not only when waves break just before pile, but also “secondary wall” slams against after breaking. With initial height increasing, will increase, growth decrease as slope angle increase. For inclined piles around point, force usually occurs an inclination ? = ?22.5° or 0°.

Experimental and Numerical Studies on Wave Breaking Characteristics over a Fringing Reef under Monochromatic Wave Conditions
Fringing reefs play an important role in protecting the coastal area by inducing wave breaking and wave energy dissipation. However, modeling of wave transformation and energy dissipation on this topography is still difficult due to the unique structure. In the present study, two-dimensional laboratory experiments were conducted to investigate the cross-shore variations of wave transformation, ...

Wave height as well as water depth at the breaking point are two basic parameters which are necessary for studying coastal processes. In this study, the application of soft computing-based methods such as artificial neural network (ANN), fuzzy inference system (FIS), adaptive neuro fuzzy inference system (ANFIS) and semi-empirical models for prediction of these parameters are investigated. Th...

متن کاملEstimation of Hydrodynamic Forces on the Cylinderical Smooth Piles to Random Waves and Currents
Most Codes such as API and BSI recommend Morison’s equation to estimate hydrodynamic forces on offshore structures. Significant differences exist among these Codes due to using different methods of analysis and estimation of force coefficients. In this paper, data from full scale tests have been used to evaluate random waves and uniform current actions on the smooth piles. Four time and ...
