支板型线对压气机中介机匣性能影响的试验研究
An experimental study of the effect of the struts profile on the performance of the compressor intermediate duct
摘要
Abstract
To clarify the influence of struts on the aerodynamic performance of the intermediate duct,a comparative experimental study was conducted on two types of struts of the same compressor intermediate duct in a ship gas tur-bine.Results showed that the total pressure loss coefficient of the modified struts decreased by 37%,79%,and 77%at 0.2,0.3,and 0.4Ma,respectively.The wake loss of the prototype strut was much greater than that of the modified strut,but the oil flow in the mainstream area was similar to the aerodynamic measurement results,impl-ying that the axial pressure change in the main flow is unaffected by the profile of the struts.However,compared with the original strut,the modified struts can effectively reduce the aerodynamic loss of the intermediate duct.关键词
