| 1 | Hydrodynamic performance and structural response characteristics of the double-slotted vertical cambered V-Type otter board显示文摘Vertical cambered V-type otter boards are widely used in large and medium-sized trawlers for their good stability and adaptability to various water layers.However,limited numerical studies on the hydrodynamic performance and structural strength of this type of otter board have been published.In this study,we established the three-dimensional numerical model of the double-slotted vertical cambered V-type otter board according to its special structure and stress feature.We compare the hydrodynamic performance results of our model with those of previous experiments.Using this model,we analyzed the influence of parameters such as attack angle,aspect ratio,dihedral,and deflector angles on its hydrodynamic performance.Moreover,the structural response characteristics of the otter board under typical working conditions were studied.We believe our results will provide theoretical reference for the structural design and optimization of the vertical cambered V-type otter board. | Wenhua Chu Gang Chen Xuchang Ye Xiufang Cui | 2020 | Aquaculture and Fisheries2020，5，4： | 5 |
| 2 | Application of Numerical Simulation for Analysis of Sinking Characteristics of Purse Seine显示文摘This study applies the mass-spring system to model the dynamic behavior of a submerged net panel similar to the shooting process in actual purse seine fishing operation. Modeling indicates that there is insufficient stretching with the net panel under the floatline in the prophase of the shooting process. Sinkers at different locations along the leadline descend successively after submergence, and the sinking speed decreases gradually with elapsed time until attainment of a stable state. Designs with different current speeds and sinker weights are executed to determine the dimensional shape and sinking characteristics of the net. The net rigged with greater sinker weight gains significantly greater sinking depth without water flow. Compared with the vertical spread of the net wall in static water, the middle part of the netting presents a larger displacement along the direction of current under flow condition. It follows that considerable deformation of the netting occurs with higher current speed as the sinkers affected by hydrodynamic force drift in the direction of current. The numerical model is verified by a comparison between simulated results and sea measurements. The calculated values generally coincide with the observed ones, with the former being slightly higher than the latter. This study provides an implicit algorithm which saves computational loads for enormous systems such as purse seines, and ensures the accuracy and stability of numerical solutions in a repetitious iteration process. | ZHOU Cheng XU Liuxiong ZHANG Xinfeng YE Xuchang | 2015 | Journal of Ocean University of China2015，14，1： | 4 |
| 3 | The wheat sucrose synthase gene TaSus1 is a determinant of grain number per spike显示文摘Some haplotypes of the sucrose synthase gene TaSus1 are associated with thousand-grain weight(TGW)in wheat(Triticum aestivum L.).However,no mutations have been identified within the gene to test this association.The effects of TaSus1 on grain number per spike(GNS)also are largely unknown.Our previous genome-wide association study identified TaSus-A1 as a candidate gene controlling fertile spikelet number per spike(FSN).In the present study,we generated two independent mutants for the three TaSus1 homoeologs by CRISPR/Cas9-mediated genome editing.The triple mutants displayed lower FSN,GNS,grain number per spikelet(GNST),and TGW than wild-type plants.In 306 hexaploid wheat accessions,two single-nucleotide polymorphisms in TaSus-A1 contributed differently to GNS.Introgression of the two alleles into a wheat genetic background confirmed their effects.The alleles differed in geographical distribution among the accessions. | Liping Shen Lili Zhang Changbin Yin Xiaowan Xu Yangyang Liu Kuocheng Shen He Wu Zhiwen Sun Ke Wang Zhonghu He Xueyong Zhang Chenyang Hao Jian Hou Aoyue Bi Xuebo Zhao Daxing Xu Botao Ye Xuchang Yu Ziying Wang Danni Liu Yuanfeng Hao Fei Lu Zifeng Guo | 2024 | The Crop Journal2024，12，1： | 0 |
| 4 | Numerical simulation on the mechanical properties of marine float显示文摘As the key structure of buoyancy and dynamic lift generation,the float is one of the most important attachments of the fishing gear in ocean fishery.For the special work environment,the float may deform and move under the hydrodynamic force when it works.At the same time,the motion may cause the impacting action from fluid and structures around.Then the investigation of the mechanical behavior of the float is of important significance for the structural design and performance optimization of the fishing gear,and even for the development of the ocean fishery.The three-dimensional numerical model of marine float working in the flow field was established based on the Computational Fluid Dynamics(CFD)method and the finite element(FEM)method according to the structural form and the mechanical characteristics in operation.The hydrodynamic performance and impact resistance were analyzed,and the response mechanism of float structure under the action of hydrodynamic load and impact load was summarized.It aims at providing basic theory support for the structure design and optimization of marine float and the related fishing gear. | Wenhua Chu Chunqing Yin Gang Chen Haoran Li Xuchang Ye | 2021 | Aquaculture and Fisheries2021，6，4： | 0 |
