典型高负荷大弯角压气机叶型的标准叶栅试验
Standard cascade test for typical high-load and large turning angle compressor arfoils
摘要
Abstract
Reliable and comprehensive compressor cascade test data are essential for establishing high-load com-pressor design systems and verifying the accuracy of numerical methods.In response to the demand for standard cas-cade test data of high-load compressor blade roots,the absence of authoritative test data of China,the inadequacy of publicly available data for high-load design needs,and the issue of data misuse due to the lack of flow field quality de-tection,the National Science and Technology Major Project Group conducted extensive research and discussions.With the support of the research results from Northwestern Polytechnical University on the influence mechanisms and regulation strategies of planar cascade wind tunnel flow field quality,the independently designed modern high-load compressor standard model cascade NPU-28(with a blade camber angle of 43.5°,solidity of 1.72,and diffusion fac-tor of 0.5)was established.This study obtained extensive experimental data,including cascade attack angle charac-teristics,isotropic Mach number on the blade surface,total pressure loss coefficient at the cascade channel exit,and exit flow angle for nine operating conditions within the inflow Mach number range of 0.4 and attack angle range of-10.9° to 5.1°.The data also provide flow field quality parameters,such as inflow Mach number uncertainty,axial velocity density ratio,and exit periodic index,along with measurement positions,test conditions,and inflow turbu-lence intensity,offering complete test information.关键词
