摘　　要：以连续方程、动量方程、Reynolds应力方程和RANG湍流k-ε模型为控制方程,采用流固耦合理论追踪耦合界面,建立了混流式水轮机数值模型。通过ADINA软件平台,采用流固耦合模块,实现了转轮叶片与内部流场耦合的模拟,得到了转轮结构的应力应变、流场的压力、流速和k-ε分布。The mathematical model of the Francis turbine was developed by using continuity equation,momentum equation,Reynolds stress equations and RANG turbulence k-ε model as the governing equations,and the fluid-structure interaction method to trace the interaction surface.Based on the ADINA software platform,the flow field of Francis turbine was simulated,and the stress-strain of runner,the distribution of pressure,velocity and k-ε of flow field were obtained.
