摘要
作为跨声速单级压气机基础研究工作的一部分,本文在过去完成的跨声速流场准三无迭代解的基础上,发展了在任意翘曲的S_1流面和若干个S_2流面上跨声流函数解相互迭代的全三无计算程序体系。对CAS跨声单转子内部流场进行了验算。经过七轮迭代,第一次得到了三元跨声流场(不假定无旋)全三元迭代解,验证了跨声速全三元迭代计算的收敛性。
As a part of the research program for CAS research transonic compressor, a full 3-D iterative solution procedure has been set up, which consists of the calculations of transonis flow fields along a number of arbitrary twisted S1 stream surfaces and a number of S2 stream surfaces.Based on the previously obtained quasi 3-D solution, a converged full 3-D iterative solution to analyze the detailed transonic flow field within the CAS axial compressor rotor has been obtained after seven iterative calculation between S1 and S2 stream surfaces using the present procedure. The characteristics of full 3-D flow field are discussed in detail.
