建筑景观瀑布的水力学实验研究

A hydraulic research on architecture scenery waterfall

首次给出了建筑景观瀑布的命名 ,并进行了水力学实验研究 .根据实验数据分析归纳出景观瀑布的阻力系数ζ ,流速系统φ及 K值 (溢出口水深 /壅水高度 )等主要水力参数与雷诺数间的关系 .为了工程水力学设计的应用 。

First of all, the flow pattern is named architecture-scenery-waterfall in this paper. A hydraulic research has been performed by experiment.Based on the experimental data,some relationships between Raynolds number Re and other hydraulic parameters of the architecture-scenery-waterfall flows,such as drag coeficient ζ,velocity coeficient φ and ratio K are obtained.For application to hydraulic calculation in engineering design,an reifferative calculation method to determine the flowrate Q is given,where a practical example is included.
