摘要:

为研究窄缝挑夫水力特性,利用数值模拟技术,结合具体工程实例,通过对曲面贴角体窄缝式挑坎内压力特性、流速分布及挑射水舌形态等水力参数进行计算分析,提取了物理模型无法获得的较为详细的流场信息。该计算结果能够为类似工程起到一定指导作用。

关键词: 窄缝式消能工, 数值模拟, 压力特性, 流速分布, 水舌形态

Abstract:

By using numerical simulation, the hydraulic parameters inclusive of pressure characteristic, velocity distribution and nappe form in slit-type flip bucket with curved surface were calculated and analyzed. What’s more, detailed information of flow field which cannot be acquired from physical models were obtained. This research serves as a guide for similar engineering.

Key words: slit-type energy dissipator, numerical simulation, pressure characteristic, velocity distribution, nappe form
