摘要
向心压气机的通流部件主要包括:进气道、动叶栅、静叶栅、出气道,本文对除静叶栅、动叶栅之外的静止通流部件的子午面进行设计,进气道、出气道子午面设计采用等截面法,能保证进出气均匀、轴向对称;并对所设计的向心压气机进行了整机模拟及变工况分析。结果表明,所设计的向心式压气机气动性能符合要求,向心式压气机是可行的。
Centripetal compressor mainly consists of four component include an inlet, a rotor cascade, a stator cascade and an outlet. The inlet and outlet passage are regarded as constant cross section to ensure the uniformity of air distribution and axial symmetry during the design of the inlet and outlet passage. And numerical ~nalysis on the designed compressor and its flow characteristics are carried out both in design and off;design conditions in the paper. Result shows that the designed compressor have good performance, the centripetal compressor is feasible.
