Numerical Study Of Tidal Energy And Tidal Energy Flux In Yueqing Bay

Tidal energy per unit area is the body of the water column with the sum of the kinetic energy and potential energy, and tidal energy flux is per unit width per unit time can be adopted by the tide from the surface to the bottom section. Bay tidal wave and tidal energy reserves has been a driving force to pass laws deposition, tidal water exchange capacity development and utilization of research concern. Master bay tidal energy and tidal energy flux characteristics, not only helps to improve the distribution of tidal bay's understanding, but also for the tide to provide theoretical support for the development and utilization. This paper calculated the trend in Yueqing Bay field, and verified using field data simultaneously, the results show that the model can correctly simulate the trend of Yueqing Bay field, On this basis, through the preparation process, to further simulate the tidal energy and tidal energy flux. Again, on the tidal energy (kinetic and potential energy) reserves the size of the distribution in space to study, the kinetic energy in terms of exposed beaches, floodplains or tidal cycle, the average spatial distribution of cases showed the same distribution with depth; potential in space The distribution of performance consistent with tidal range, the maximum potential energy in the tidal floodplain and the maximum size of exposed beaches do when the distribution is different. Then flows to pass laws further discussion, the high energy region Yueqing Bay were concentrated in a narrow deep channel and cross section area; another unit can be concentrated in a relatively low tide near the mouth of the China Bay tidal differences and Truman Bay tidal flat top, Jiang Yan Hill, Mao Dan Hill, Simon Hill and more curved near the coastline. Tidal energy input stage, tidal energy flux generally reflect the distribution of ground bay west of the East China for becoming a small tidal differences, and input from the bay to the Bay in the north as the Bay Harbour Office, more complex terrain, and there are many islands existence, making tidal energy flux contours roughly parallel with the shoreline; in tidal output stage, the bay is bounded to the Bay area, then the tidal variation from east to west, the output decreased by the bay Bay to Bay to the top, then the output of a tidal wave. Tide from Yueqing Bay to Bay, off the top input process, energy flux appears to have gotten a small trend, trend top from Yueqing Bay, the output of the process of the open sea, the energy flux profile showed a clear increasing trend, but In large and small, during the whole tidal cycle, the overall performance of the total energy flux input than output. Yueqing Bay from the open sea to the total input energy flux, Yueqing Bay, the total energy flux of the open sea and the size of the tidal cycle, the output of the net tidal energy flux is the appropriate time with the increase of increasing tide.
