浮式风机气动-水动耦合特性数值模拟（英文）

The exploration for renewable and clean energies has become crucial due to environmental issues such as global warming and the energy crisis. In recent years,floating offshore wind turbines(FOWTs) have attracted a considerable amount of attention as a means to exploit steady and strong wind sources available in deep-sea areas. In this study, the coupled aero-hydrodynamic characteristics of a spar-type 5-MW wind turbine are analyzed. An unsteady actuator line model(UALM) coupled with a twophase computational fluid dynamics solver naoe-FOAM-SJTU is applied to solve three-dimensional Reynolds-averaged NavierStokes equations. Simulations with different complexities are performed. First, the wind turbine is parked. Second, the impact of the wind turbine is simplified into equivalent forces and moments. Third, fully coupled dynamic analysis with wind and wave excitation is conducted by utilizing the UALM. From the simulation, aerodynamic forces, including the unsteady aerodynamic power and thrust, can be obtained, and hydrodynamic responses such as the six-degrees-of-freedom motions of the floating platform and the mooring tensions are also available. The coupled responses of the FOWT for cases of different complexities are analyzed based on the simulation results. Findings indicate that the coupling effects between the aerodynamics of the wind turbine and the hydrodynamics of the floating platform are obvious. The aerodynamic loads have a significant effect on the dynamic responses of the floating platform, and the aerodynamic performance of the wind turbine has highly unsteady characteristics due to the motions of the floating platform. A spar-type FOWT consisting of NREL-5-MW baseline wind turbine and OC3-Hywind platform system is investigated. The aerodynamic forces can be obtained by the UALM. The 6 DoF motions and mooring tensions are predicted by the naoe-FOAM-SJTU. To research the coupling effects between the aerodynamics of the wind turbine and the hydrodynamics of the floating platform, simulations with different complexities are performed. Fully coupled aero-hydrodynamic characteristics of FOWTs, including aerodynamic loads, wake vortex, motion responses, and mooring tensions, are compared and analyzed.     

用于反应堆舱的视频采集技术

基于核动力船舶反应堆舱的具体应用需求,研制了一款无源、小型化、模块化,具有良好耐高温和耐辐照特性的视频采集装置。它利用光纤阵列成像技术和基于稀疏表示的图像超分辨率重建算法来获取高质量的图像。通过主观质量评分法,将该装置与传统的电子摄像管摄像机、CCD/CMOS彩色/黑白摄像机进行一系列的耐高温、耐辐照的实验对比分析。不同环境下的实验结果表明,该视频采集工作稳定可靠,完全满足设计要求。另外,该装置还具有良好的泛化推广能力,稍加适应性设计,即可应用于其他类似的环境中。     

废旧电池回收处理

人们在社会生活中几乎一天也离不开电池,废电池数量也随之加大.废电池中的有毒重金属污染地下水和土壤,对生态环境和人类健康造成了很大的危害.由于电池污染具有周期长、隐蔽性大等特点,其潜在危害相当严重,处理不当还会造成二次污染.我国废旧电池的回收处理还存在很多的问题,我们应借鉴发达国家的经验,建立一套完善的废旧电池回收体系.     

环境激素与人类健康

含有环境激素的化学合成物，在日常生活中比比皆是，环境激素对人类和生物的激素分泌机能造成极大的破坏性，同时给地球生态环境造成巨大威胁，成为人类健康的可怕杀手。环境激素同地球变暖、臭氧层遭到破坏一样，成为全球的三大难题，因而引起世界社会各界的高度重视。
