船后喷水推进器水下辐射噪声源脉动流场的数值计算

为避免尺度效应对噪声性能的影响,文章研究探索了在实尺度条件下装船后喷水推进器噪声声源的数值计算方法。首先,基于分离涡模型对国外某喷水推进泵内部非定常流场进行了数值模拟,将计算得到的不同转速下泵的功率值与厂商提供数据进行对比,最大误差在2.0%以内,验证了数值计算方法的准确性和有效性。其次,完成了实尺度条件下某"船体+喷水推进泵+进水流道"系统带自由液面的非定常流场的数值计算。提取了实船条件下喷水推进器流道进口处的不均匀速度场,将其加载到单个喷水推进器数值计算模型的进口边界。进而,采用分离涡模型对该船后"喷水推进泵+进水流道"内部非定常流场脉动压力进行数值计算,分析了各个特征截面压力脉动的频域特性,为下一步准确计算喷水推进器噪声提供了有效的脉动流场信息。

Formation of Denmark Strait overflow water and its hydro-chemical composition

The dense overflow across the Denmark Strait is investigated with hydrographic and hydro-chemical data and the water mass composition of the Denmark Strait Overflow Water (DSOW) is determined by multivariate analysis. Hydrographical properties, the transient tracers CFC-11 and CFC-12, oxygen and nutrients are utilized for the water mass definitions. Distribution and characteristics of water masses north of Denmark Strait are described, the important water masses at the sill and the variability on weekly time-scales are discussed, and the entrainment and mixing of water into the overflow plume in the northern Irminger Basin is calculated. The analysis indicates that water masses both from the Nordic Seas and the Arctic Ocean are important for the formation of DSOW. It is found that water masses transported with the East Greenland Current make up about 75% of the overflow at the sill. The overflow at, and shortly south of, the sill is inhomogeneous with a low-salinity component dominated by Polar Intermediate Water. The high-salinity component of the overflow is mainly of Arctic origin. The water mass composition, and the short-term variability for 7 repeats of sections close to the sill are described, and these illustrate that the overflow is in fact a composite of a number of water masses with different formation and transport histories. This indicate that the overflow is a robust feature, but that it responds to variations in the circulation or atmospheric forcing that influences the formation of intermediate and deep water masses within the Arctic Mediterranean and the North Atlantic. At a section about 400 km south of the sill the overflow is well mixed and modified by entrainment of, mainly, Iceland–Scotland Overflow Water and Labrador Sea Water, together constituting 30% of the overflow plume. The entrainment of Middle Irminger Water dominates shortly downstream of the sill, before the overflow plume reaches too deep but the entrainment seems to be intermittent in time.

Impact of regulation on the performances of long-distance transport services: A comparison of the different approaches in Sweden and Norway

Despite the many socio-economic similarities between Sweden and Norway, differences in jurisdiction, organisation, cooperation, and financing of long-distance passenger train and coach services have led to the development of four distinctively different ways of serving the markets. This paper describes how the train and coach markets have developed in the two countries, with emphasis on regulatory and industrial structure and a couple of performance variables.Looking at passenger rail, both countries separated infrastructure from operation over a decade ago. However, while Norwegian rail is characterised by an almost monopoly supplier, rail services in Sweden are partly decentralised to the responsibility of county authorities and are widely subjected to competitive tendering. The rest of the network is about to be opened up for on-the-track competition. Swedish Rail (SJ) has spent the last decades consolidating its core business (passenger rail) and sold out its other businesses. In contrast, the Norwegian state rail (NSB) has expanded its business to become a major bus operator and property owner, with extensions also into the Swedish market.The coach industry was more recently deregulated in both countries. The Swedish coach market is dominated by privately owned companies operating services to and from Stockholm. In Norway, state-owned NSB is a major coach operator on medium distance routes, and is also the largest partner of Nor-Way Bussekspress which totally dominates long-distance coach services. Further, the Norwegian coach market is characterised by cross-ownership and cooperation which has enabled an extensive route network which covers most of Norway.We find distinct differences in achievements in the two modes and in the two countries. Swedish rail services have succeeded in winning market shares and in renewing and developing both infrastructure and service levels to a greater extent than the Norwegian model. On the other hand, the Norwegian coach market seems to be more developed and efficient compared to its Swedish counterpart.The paper concludes with a discussion on the possible links between the different approaches and the performance observed, with the aim to stimulate further and more detailed research on some important issues.

丁坝群坝田与主流水沙交换与冲淤机理综述

丁坝群不同平面布置方案下坝田与主流间的泥沙交换和地形变化是长江口深水航道回淤机理及减淤措施研究的重要内容,但以往研究不多。坝田与主流的泥沙交换及地形变化与紊流结构及时均流场有关,即与坝田-主流主界面混合层的大尺度相干结构和坝田内时均大尺度环流有关。在出水丁坝和淹没丁坝情况下坝田与主流的质量交换系数变化不大,约为0. 02左右。坝田不存在悬沙的平衡剖面(Rouse分布),悬沙和底沙均存在指向坝田的净输沙。坝田淤积达到准平衡状态需要5～6 a,但基本上在前2 a就达到了平衡。
