| 1 | INCIPIENT MOTION OF NON-COHESIVE SEDIMENT UNDER ICE COVER-AN EXPERIMENTAL STUDY显示文摘Based on a series of experiments under both ice-covered and free surface conditions, the present article discusses the role of flow velocity and critical shear Reynolds number for incipient motion of bed material. The influence of the resistance coefficients of both the underside of the ice cover and the channel bed on the location of the maximum velocity has been discussed. In addition, the impacts of ice and composite resistance coefficients on flow velocity for incipient motion of bed material have been assessed. The diagram describing the critical shear Reynolds number and the dimensionless shear stress for the incipient motion of sediment under ice covered conditions with different under cover resistance coefficient has been established. The effects of grain size on densimetric Froude number for incipient motion of bed material have been investigated. A relationship between the densimetric Froude number for incipient motion of bed material and the median grain size of bed material as well as the roughness coefficient of channel bed and roughness coefficient of ice cover has been established. | WANG Jun SUI Jue-yi KARNEY Bryan W. | 2008 | Journal of Hydrodynamics2008，20，1： | 15 |
| 2 | EFFECTS OF RIVER ICE ON STAGE-DISCHARGE RELATIONSHIPS——A CASE STUDY OF THE YELLOW RIVER显示文摘Using field observations at four gauging stations along the Inner Mongolia Reach of the Yellow River in China, this paper explores effects of the ice on the hydraulics of this river reach for four different conditions, namely: under open channel flow, during ice-running period, the ice-covered period, and the river break-up period. The rating curves were found to be well recognized under open channel situations, but were sometimes poorly defined and extremely variable under ice conditions. The results also show that the water level is insensitive to flowing ice prior to freeze-up. However, significant, but hardly surprising, variations were observed during ice-covered conditions. The rating curves for both the ice covered condition and river ice breakup period are developed and some related hydraulic issues are examined. Additionally, the impacts of the ice accumulation and associated riverbed deformation during ice period on the rating curves are discussed. | Jueyi SUI Ronald THRING Bryan W.

| 3 | 热力学法在泵性能测试中的应用及与传统方法的比较显示文摘全球范围而言,水泵效率和性能的热力学测试方法大约于十多年前在工业领域开始得到大量应用,但目前在泵站测试中使用还不是很广泛。由于缺少直接的工业应用标准去保证热力学法测试结果的准确可靠,且多数泵站自身又缺乏足够经验来开展独立研究测试,所以迫切需要一些通用性的指导原则来推动相关领域的进展。通过对多城市多泵站的水泵效率测试和研究,本项目完成了41个泵站的152个城市供水水泵的性能测试。其中57个水泵同时使用了热力学法和传统方法。通过大量的现场测试,并与采用电磁流量计、超声波流量计等传统测试方法的对比,积累了许多关于热力学法和传统方法在水泵性能测试中的经验和技巧;测试研究成果进一步明确了热力学法的适用条件和范围,通过对实测中遇到的各种情况的处理和总结,提出了热力学方法的通用性指导应用原则。 | 刘鑫 KARNEY Bryan RADULJ Djordje 王正伟 | 2015 | 机械工程学报2015，51，10： | 4 |
