孔口淹没出流的CFD数值模拟计算探讨

CFD Numerical Simulation Analysis of Orifice Submerged Outflow

利用深圳市北线引水工程高位水池薄壁堰改造契机,基于薄壁堰孔口淹没出流,分别以水力学理论计算成果为基础,开展CFD数值模拟计算,并利用室内物理模型试验加以论证,将模拟值与计算值、试验值进行对比分析,结论高度吻合。研究成果可为类似水工结构设计的CFD数值模拟计算提供一种经验模式和参考。

Based on the reconstruction of thin-plate weir of high position reservoir of Shenzhen north line water diversion project, this study demonstrates the orifice submerged outflow of thin-plate weir from hydraulics theory calculation, CFD numerical simulation and physical model experiment. By comparing the simulated, calculated and experimental results, the results are in good agreement. This study is expected to provide an empirical model and reference for CFD numerical simulation of similar hydraulic structure.
