摘要
介绍了采用紊流模型和有限体积方法,通过数值模拟解决几类典型的高坝水力学问题:(1)水垫塘三元典型流态模拟、水垫塘水体消能分区;(2)具有未知底边界的冲刷坑水流模拟;(3)洞塞消能、竖井旋流式消能和龙抬头式泄洪洞反弧段的流场模拟;(4)掺气挑坎形成的高紊动掺气水流的流场模拟。这些问题来源于实际工程,成果也已应用于工程设计中。
This paper introduces turbulent model and finite volume method. Hydraulic problems on high dam are solved by numerical simulation. Four typical study cases are introduced in the paper： （1） 3D flow pattern simulation in cushion pool , the regionalization of cushion pool regarding energy dissipation; （2） flow pattern simulation in scouring pool with the moving boundaries; （3） flow field simulation in shaft spillway with whirling current as well as flow on ogee dam in flooding tunnel with high inlet ; （4） strong aerification turbulent flow formed by air entrainment on aerated weir. All these cases are from real hydraulic engineering projects and the study results have been applied to engineering design.
