摘要:
以25MW凝气式汽轮机的某级叶片为研究对象,利用ANSYS Workbench平台中的旋转机械分析系统对该级叶片进行了静、动联合三维数值模拟优化.结果表明,优化后叶片压力系数分布较好,降低了叶片表面压差分布,有效控制径向二次流损失;总压损失系数有所减小,平均总压损失系数降低1 % ;等嫡效率由原来的92.099%提高至93.157% .优化后的叶型明显提高了气动性能,降低叶型能量损失，增加了汽轮机效率.
Abstract:
The three-dimensional numerical simulation and optimization of the last stage of a 25 MW condensa-ble steam turbine are conducted by using ANSYS Workbench,a platform of analysis system specially for therotating machinery. The results show that the modified blade has a better pressure coefficient distribution,re-duces the differential pressure distribution of blade surface,effectively controls the radial secondary flow los-ses.Total pressure loss coefficient is reduced,and the average total pressure loss coefficient is reduced by 1% . Isentropic efficiency increases from 92. 099 % to 93.157 % . After optimization,the aerodynamic per-formance of the blade increases obviously,the energy loss in the blade is reduced and the efficiency of steamturbine increases.
