Research On Wave Motion Mathematical Model In Wave Energy Test Site

The use of traditional fossil energy has brought serious environmental problems, and the future will have to face the depletion of resources and energy crisis, more and more people attach importance to the development of the use of renewable energy, which can be used as widely distribution, large storage capacity of renewable clean energy, its development and utilization is the inevitable requirement of the development of the world. Wave energy theory of usable amount and the actual amount can be developed maximum, research of wave energy development technology is of great significance to solve the energy crisis and environmental pollution problems. In order to test and assess the ocean energy technology R&D, ocean energy test site is necessary to establish. The limited nature of the sea area, as far as possible to place multiple devices in a limited range, you need to consider the influence of device on the wave field, distance and area of influence, and provide scientific basis for the device and reasonable layout.Starting from the N-S equation, the three-dimensional fluid along the depth for vertical integration, Systematically deduced two-dimensional Boussinesq equations. By the two-dimensional Boussinesq equation as the basic controlling equation, using the fully implicit difference discretization scheme and a square grid, a 2D wave mathematical model is established, adopting the Thomas algorithm method to solve, can simulate the linear wave vertical incidence and oblique incidence, calculate the wave field of various wave conditions.The establishment of the wave model applied to Dawanshan wave test site, research power generation device hydrodynamic effects of the wave field around, simulate the linear wave motion in interesting area, freedom of movement in the process of device without anchorage in waves and the effects of anchoring device for the wave field, qualitative analysis of wave field under different tidal level and wave factors. According to the actual situation of the test site, simulate wave field with or without attenuation, statistic the impact distance and area for each program in wave field.
