A note on the hydrodynamics of a tail tube buoy

This note presents some analytical results for a tail–tube buoy configuration frequently used in wave energy conversion. The overall approach is based on Falnes and McIver's (Falnes, J., McIver, P., 1985. Surface wave interactions with systems of oscillating bodies and pressure distributions. Applied Ocean Research 7 (4), 225–234) extension to floating oscillating water columns of Evans' (Evans, D.V., 1982. Wave power absorbtion by systems of oscillating surface pressure distributions. Journal of Fluid Mechanics 114, 481–499) theory of oscillating pressure distributions. The diffraction air-flow flux through the tube and the diffraction wave force on the flotation collar are obtained using the formulation of Garrett (1970, 1971) (Garrett, C.J.R., 1970. Bottomless harbours. Journal of Fluid Mechanics 43 (3), 433–449. Garrett, C.J.R., 1971. Wave forces on a circular dock. Journal of Fluid Mechanics 46 (1), 129–139). Results can be used in sizing the tube and collar for efficient energy conversion.

波浪能直接驱动机动浮标的推进机构设计

移动观测平台是海洋环境立体观测系统的重要组成部分。遥控水下机器人(ROV)、自治水下机器人(AUV)等移动平台由于需要支持船只和能源供给的限制,影响了它们长时间和大范围使用。本文利用波浪垂荡运动设计一种新型波浪能驱动的机动浮标,该系统由水上浮体和水下推进机构两部分组成,利用波浪垂荡运动,推动水下推进机构叶片的摆动,引起水下推进机构在水平方向向前的升力,使水下推进机构以及水上浮体实现无外在能源供给的自主运动。本文设计制造了波浪驱动机动浮标的实验样机,并进行了海试。实验表明,在中等海况条件下可以实现机动浮标的无动力前进。该设计为海洋环境调查、海洋生态监测和溢油跟踪等提供了一种有效的移动监测平台。     

A study of transport and impact strength of Fukushima nuclear pollutants in the north pacific surface

Based on the statistics of surface drifter data of 1979–2011 and the simulation of nuclear pollutant particulate movements simulated using high quality ocean reanalysis surface current dataset, the transport pathways and impact strength of Fukushima nuclear pollutants in the North Pacific have been estimated. The particulates are used to increase the sampling size and enhance the representativeness of statistical results. The trajectories of the drifters and particulates are first examined to identify typical drifting pathways. The results show that there are three types of transport paths for nuclear pollutants at the surface: 1) most pollutant particles move eastward and are carried by the Kuroshio and Kuroshio-extension currents and reach the east side of the North Pacific after about 3.2–3.9 years; 2) some particles travel with the subtropical circulation branch and reach the east coast of China after about 1.6 years according to one drifter trajectory and about 3.6 years according to particulate trajectories; 3) a little of them travel with local, small scale circulations and reach the east coast of China after about 1.3–1.8 years. Based on the particulates, the impact strength of nuclear pollutants at these time scales can be estimated according to the temporal variations of relative concentration combined with the radioactive decay rate. For example, Cesium-137, carried by the strong North Pacific current, mainly accumulates in the eastern North Pacific and its impact strength is 4% of the initial level at the originating Fukushima area after 4 years. Due to local eddies, Cesium-137 in the western North Pacific is 1% of the initial pollutant level after 1.5 years and continuously increases to 3% after 4 years. The vertical movement of radioactive pollutants is not taken into account in the present study, and the estimation accuracy would be improved by considering three-dimensional flows.     

NCEP再分析资料和浮标观测资料计算海气热通量的比较
