摘　　要：本文讨论了准三维S1、S2流面迭代及全三维流场计算的特点,对叶轮机械气动设计流程中的S1计算部分作了改进:通过定量分析全三维流场计算结果并从中提取若干S1流面上的物理参数,反馈给S2流面计算进行迭代以及修改叶片造型,将多个S1流面的计算与全三维校核融为一体,从而简化了设计流程,并提高设计的准确性。按照改进的流程设计了一级风扇,效果良好,验证了该方法的可行性。Some characteristics of quasi-3D S1/S2 streamsurface iteration and full-3D flow field calculation are discussed in this paper,and some improvements on S1 calculation of turbomechinery aerodynamic design process are made： some parameters on S1 streamsurfaces are extracted by analyzing full-3D flow field calculation quantitative,then feedbacked to S2 streamsurface calculation and blade modeling.This method combines S1 streamsurfaces calculation and full-3D check together,which could make design process simpler and improve accuracy.One-stage fan was designed with the improved method effectively,which validates the feasibility of this method.
