基于水跃的综合性实验设计与教学实践

Comprehensive Experimental Design Based on Water Jump Experiment and the Teaching Practice

  • 摘要: 该文设计了以水跃实验为核心的综合性实验,涵盖了堰流、闸孔流、明渠流等水流流态,涉及了堰流系数、闸孔流量系数、共轭水深、佛汝德数、水跃跃长、水跃消能率、流速分布等水力学特性指标。教学方案中注重培养学生自主设计边界条件与实验方案,成果分析中强调文献综述与对比分析,并且提出了总结交流环节。实验方案可较大程度发挥学生的主观能动性,进而提高学生的数据分析能力,达到在工程实践中灵活运用知识的目的。

     

    Abstract: This paper designs a comprehensive experiment based on the water jump experiment, it covers the flow patterns such as weir flow, sluice flow, open channel flow. It involves hydraulic characteristics such as weir coefficient, conjugated water depth, Froude number, water jumper length, water jump energy dissipation rate and flow velocity distribution. The teaching plan plays attention to cultivating students’ independent design boundary conditions and experimental programs. The results analysis emphasizes literature review and comparative analysis, and proposes a summary communication link. The experimental program can give full play to the subjective initiative of the students, thereby improving the students’ data analysis ability and achieving the purpose of flexible use of knowledge in engineering practice.
