【摘要】 通过对单缸10万千瓦汽轮机末级流场的试验研究,掌握了湿蒸汽区的测试技术,证实了按三元流控制涡理论设计的末级叶片和根据轴对称势位流动流线法设计的排汽缸扩压器是成功的.并具有良好的变工况性能.更多还原

【Abstract】 Based on the experimental test on the last stage flow field of a 100 MW single casing steam turbine, method for wet steam zone measuring was obtained. The design of the last stage blade based on the philosophy of three dimensional controllable eddy current as well as the design of the diffuser according to the flow line of the symmetrical potential flow are proved to be successful and present a fairly good performance under variable operating conditions.更多还原
