摘　　要：为满足井下紧凑的空间和特殊的叶片设计需求,对涡轮发电系统中的关键部件涡轮进行优化和性能预测。涡轮叶片采用一元流理论进行叶栅设计,借助参数化造型建模方法、运用计算流体力学(Computational Fluid Dynamics,CFD)软件对井下涡轮进行全三维粘性流场数值分析和性能预测。实验表明涡轮转速范围在2 000~5 000 r·min^(-1),排量范围在600~850 L·min^(-1),功率大于500 W,满足设计要求。In order to meet the compact underground space and special blade design requirements,the key components of turbine power generation system were optimized and performance forecast.The whole three-dimensional viscous flow field is numerically analyzed and its performance is predicted by means of parametric modeling method and Computational Fluid Dynamics(CFD)software.The experimental results show that the turbine speed range is 2000~5000 r·min^(-1),the displacement range is 600~850 L·min^(-1),and the power is greater than 500 W,which meets the design requirements.
