摘要: 本文提供了一个带有透平级子午通道形式(可以规定等内径。等中径、等外径或某个直径的具体数值)、子午通道扩张角、轮毂比范围、动叶片最大应力、与荡动频率有关的D 中/L、展弦比以及与余速损失有关的α 2等多种约速成条件的最高透平级效率的级几何参数选择与平均截面上最佳气动热力学参数的计算方法。文中要用了较新的AMDC-KA损失模型,并给出了计算程序框图和具体算例。

Abstract: This paper is based on the solution of the target function ηt an optimum parameter selection method of geometrics with some constraints of engineering construction conditions has been offered. These constraint conditions are the maximum allowable centrifugal stress, the form of the meridian passage(may be lqual top diameter equal middle diameter equal root diameter or fixed concrete value of any diameter) the limitation of the passage expansion angle γ,the limitation of the minimumα2, the limitation of the Dm/ L and chord span ratio L/b.In this method a relative new loss model-AMDC-KA has been useb, only one minute on computer TQ16, we can get a satisfactory result.
