中文摘要：
采用最新CFD方法对具体工程泄洪闸水流流态进行模拟分析.先给出了数学模型和计算方法;然后结合模型实验成果,用CFD详细分析了泄流能力与水面线、压力、流速等流场参数的规律性,弄清了不良流态的原因;进而提出加大侧墙弧度以消除吸气漩涡及加大孔口断面避免脱流的措施,通过3个方案对比分析验证了其效果,并得出最佳方案的泄流能力、进水口流态及泄槽内流态、压力和速度的分布规律.
英文摘要：
The flood sluice flow has great influence on the safety of a hydraulic project. The sluice flow patterns ot a specific project are simulated and analyzed by the computational fluid dynamics （CFD）. First, the numerical model and simulating approach are given. Second, the characteristics of discharge capacity, water surface profile, pressure distributions, flow rates, and other flow parameters are analyzed by CFD results, along with some model experimental data. Third, the causes of poor flow conditions are clarified. Finally, the measures for eliminating the vortex and flow separation by increasing the side wall arc and the orifice section are proposed; their effects are validated by comparative analysis of three schemes. And the best discharge capacity, the inlet flow pattern and the tank vent flow pattern, pressure and velocity distribution are obtained.
