Aerodynamics design of two-stage counter-rotating turbine
摘要
Abstract
The factors which had impact on the forms of counter-rotating turbine were analyzed in detail based on the characteristics of counter-rotating turbine. By analyzing the counter-rotating turbine velocity triangles and how the efficiency and work ratio varied by the parameters of the velocity triangles, the regular of how to select the velocity triangles of counter-rotating turbine was developed. A new counter-rotating turbine which had premeditated the coolant was designed. The results of 3D viscous numerical simulation show that the turbine meets the design requirements with a high efficiency, and the regular was tested an verified.关键词
