竖井进流水平旋转内消能泄水道流速分布的试验研究

Experimental study on velocity distribution of horizontal vortex and inner energy dissipating tunnel with inlet shaft

本文从分析图 1所示的竖井进流水平旋转内消能泄水道的基本流态与泄流量变化规律出发 ,对该种泄水道的流速分布提出假定 ,并给出具体表达形式。根据试验量测资料 ,对轴向流速、环向流速及有关物理量的变化规律进行了分析与研究 ,这对该种泄水道水力特性的分析。

Beginning with the analysis of the basic flow pattern and discharge characteristics of the horizontal vortex and inner energy dissipating tunnel with inlet shaft, the expressions of velocity distributions in the tunnel have been supposed and established. Axial velocity, circumferential velocity and related hydraulic characteristics have been studied according to experimental data. This study will be useful for the hydraulic analysis, calculation and design of the tunnel.
