为研究采用数值模拟方法分析岸边泄洪洞水力特性的可行性,采用Fluent商业应用软件对潘口水电站岸边泄洪洞进行了三维数值模拟,得到了泄流能力、典型断面流速、沿程底板压力、水面线及洞顶富余等水力要素的分布特点。数值计算结果与模型试验结果比较表明,两者吻合较好,可见采用数值模拟方法研究潘口水电站泄洪洞的水流特性具有可行性,各种边界条件的设定较为合理,能够模拟出真实情况下的各项水力指标,研究结果对体型优化有一定指导作用。
In order to study the feasibility of using numerical simulation method to analyze hydraulic characteristics of bank spillway, three-dimensional numerical simulation of flood discharge tunnel at Pankou Hydropower Station was carried out with Fluent commercial application software. The discharge capacity, typical cross-section flow rate, , Water line and the top of the cave and other hydraulic elements of the distribution characteristics. Comparing the numerical results with the model test results shows that the two agree well with each other, which shows that it is feasible to study the flow characteristics of the spillway tunnel of Panchou hydropower station by numerical simulation. The setting of various boundary conditions is reasonable and can simulate the real situation Of the hydraulic indicators, the results of the body shape optimization has a guiding role.
