基于CFD不同AUV艇体的阻力性能分析

自主水下航行器（AUV）作为探索海洋、开发资源和军事作战等水下应用的重要手段,其速度和续航力是评价其性能优劣的重要方面。AUV在水下航行时的阻力主要取决于其几何形状和尺寸以及其表面的光滑程度,因此,研究AUV的几何形状和外观尺寸便显得尤为重要。对AUTOSUB,HUGIN,REMUS,BLUEFIN1和BLUEFIN2这5种艇型建立几何模型并进行阻力性能分析。通过采用计算流体动力学（CFD）方法进行数值模拟,并将所得结果与理论结果进行对比分析,以验证CFD模拟的可靠性及模拟的最优模式。通过对比不同直径、不同舵的展弦比、带舵和无舵、有整流罩以及相似径长比的不同艇型来比较AUV的阻力性能,最终得到艇型的阻力性能特点以及最佳艇型。研究表明：在5种艇型中,AUTOSUB型最优,其次是HUGIN型、REMUS型和BLUEFIN1型,最后是BLUEFIN2型,其中AUTOSUB型和HUGIN型适合中、高速航行,REMUS型和BLUEFIN型适合低速航行。     

Experimental assessment of the ultimate strength of a box girder subjected to severe corrosion

The objective of this paper is to describe the experimental assessment of the ultimate strength of a severely corroded box girder subjected to a uniform bending moment resulting from four-point loading. Three box girders that could simulate the behaviour of midship sections have been deteriorated in corrosive seawater environment to simulate different levels of corrosion degradation of ageing ship structures. During the deterioration process, various parameters have been controlled and the total weight lost was registered. Corroded plate thicknesses have been measured in 212 points and a statistical analysis has been performed. The resulting corrosion wastage has been fitted by a non-linear time variant degradation model. The experimental results of the ultimate strength test of a severely corroded box girder subjected to a four-point loading have been analysed. The load-displacement and moment-curvature relationship is discussed, different failure modes are identified, and the strain gauges readings are analysed.     

Quantitative estimation of the influence of surface thermal fronts over chlorophyll concentration at the Patagonian shelf

Eighteen-year (1985–2002) mean monthly SST Pathfinder data with 9 km spatial resolution have been used to estimate surface gradients by finite differences. Then the seasonal climatological means have been calculated from the intensity of these gradients, and surface thermal fronts present in the Patagonian Continental Shelf (PCS) have been located. Moreover, 6 years (1998–2003) of SeaWiFS data with approximately 4 km spatial resolution have been used to estimate monthly composite images of surface chlorophyll concentration, after which seasonal climatological means distributions have been generated. Both seasonal distributions have been analyzed together and by combining the knowledge of oceanographic processes and phytoplankton responses to light and nutrient availability, regions where the presence of a thermal front affects photosynthetic activity have been identified. Subjective criteria have been applied to define eighteen areas where phytoplankton biomass is influenced by the presence of a thermal front. In these areas, the surface chlorophyll (spatial mean and total), its relationship with the surface chlorophyll of the whole region, and the seasonal evolution of this relationship have been calculated. All frontal areas cover less than 15% of the total surface, but they contribute with over 23% of the phytoplankton annual mean biomass. Considered as a group, during summer they show high chlorophyll values very similar to those in spring. During the cold period, when the water column is vertically mixed in practically the whole of PCS, the influence of physical fronts over the biological production is minimum. The frontal zone image remains clearly defined during summer, when approximately 85% of the area will have a determined mean chlorophyll concentration, while the other 15% has a 2.45 times larger value. While three pattern trends have been identified in the frontal areas, only two of them condition the pattern of the group, due to their horizontal extension.

Perceptions of foreign exchange rate risk in the shipping industry

This is an analysis of the impact of exchange rate risk on the performance of major shipping companies from two important maritime nations, Japan and Norway. For the shipping industry, such risk is exacerbated by freight rates fixed in US dollars which must then be converted into numerous other currencies. The appreciation of the Yen against the US dollar has been such that Japanese companies have been impelled to insulate themselves from exchange rate movements by natural hedging. For Norway, where fluctuations of the Krone against the US dollar have been less dramatic, exposure has been maintained, allowing an element of speculation. In both cases the market indicates that exchange rate risk is a significant factor in the determination of corporate performance.

Radioactive tracers as a tool in coastal oceanography: An overview of the MAST-52 project

Radionuclides (⁹⁹Tc, ¹²⁵Sb, ⁹⁰Sr, ¹³⁷Cs) discharged from La Hague in France have been used to trace advection and dispersion of water masses in the “European Coastal Current” from the English Channel to the Baltic. Time-series of radionuclide measurements in water samples taken in the English Channel, at the Netherlands coast, in the German North Sea sector and in Danish waters have been compared with reported discharge values. The prospects for using ¹²⁹I measured by accelerator mass spectrometry (AMS) as an oceanographic tracer have been evaluated as positive. The ⁹⁹Tc analytical procedure have been improved and background levels of ⁹⁹Tc, ¹³⁷Cs and ⁹⁰Sr in open North Atlantic seawater without influence from European discharges have been determined. An intercomparison programme have documented the quality of the measured ⁹⁹Tc and ¹²⁵Sb data. Transit times and transfer factors from La Hague to different locations in the study area have been estimated. It is concluded, that 10% of the La Hague discharge is transported through Kattegat and that 1/3 of the inflowing Kattegat bottom water originates from the coastal current. Three fundamentally different numeric models have been further developed under the project. The measured data have then been compared with values simulated by the three models. Models as well as measured data indicate, that a close coastal transport with longer transit times and often higher concentrations than seen in the open water main current is taking place. This coastal transport is important when contaminant transport is monitored. It is concluded, that the collected data gives a unique opportunity to evaluate models on advection and dispersion of coastal water masses and contaminants. The database will be made available as a tool for the evaluation of such models.
