亚声速低反力度吸附式压气机的非定常数值研究
Unsteady Simulation of a Subsonic Low-reaction Aspirated Compressor
摘要
Abstract
ABSTRACT:In order to discover the influence of rotor-stator interaction on the aspirated compressor aerodynamic performance, numerical simulations were performed on a subsonic low-reaction aspirated compressor, and detail study was carried out to compare the difference of the aerodynamic parameters and flow field with the steady and unsteady methods. As a result, under the rotor-stator interaction, the total pressure ratio and efficiency almost have no change, and the aspirated massflow increases in the suction while decreases in the endwall; the potential effect of the stator on the rotor reduces the rotor total pressure ratio near the midspan; the rotor anti-C type wake is future twisted in the stator passage, and both ends of it are drawn together towards the midspan, which makes the stage outlet aerodynamic parameters distributions much more evenly.关键词
