摘要
目前,对大型水轮机组稳定性问题的研究成为热点和前沿问题。三峡电站的运行水头变幅大,负荷变幅也大, 机组稳定性问题更为突出,成为人们关注的焦点。应用CFD技术对混流式水轮机的内部流场进行模拟分析,对可能影响 水轮机运行性能的若干因素进行研究,可以为改善水轮机的水力稳定性能提供依据。
Research for stability of huge turbine units is very important and urgent nowadays. And stability of turbine for the three gorges becomes the focus because of its big range of height and power. Within the great progress of CFD technique, numerical simulation of the whole turbulent flow-field through a turbine can be processed. On the base of analyzing factors influencing the hydraulic properties, some ideas for enhancing design of the turbine may be offered.
