摘要
介绍了湿冷汽轮机变负荷末级 1036mm叶片的气动特性.从叶型特点、数值计算方法、分析参数分布规律及在50%、75%、100%负荷下反动度和效率等方面介绍该叶片.
Abstract
This paper introduces the 1036mm high-efficiency last stage blade which was applied to the wet cooling steam turbine.The characteristics of blade are illustrated.The Three-dimensional steady numerical results showed that the 1036mm blade has better performance than the same level blade by compared the efficiency and reactionary degree of pressure under 50%,75%and 100%load.
