Optimization Design of High Diffusion Factor Slotted Compressor Stator Blades
摘要
Abstract
As compressor blade slotting can control the development of suction surface boundary layer and reduce flow loss,this article,by adopting a slot with inlet from the leading edge of the blade and outlet from the suction surface,effectively suppresses the development of the boundary layer on the suction surface utilizing the inflow velocity impulse.The key channel geometry parameters are determined by automatic optimization method.Slotting is designed for a compressor stator blade with an inlet Mach number of 0.4/0.55/0.7 and a diffusion factor of 0.6.The results show that at the designed intake angle,the separation area of the boundary layer on the suction surface of the blade becomes smaller and the wake decreases as well,due to the control effect of the slotted jet on the boundary layer of the suction surface,which results in a decrease in the total pressure loss of the slotted blades.At large positive angles of attack,the separation area of the suction surface boundary layer thickens,and the slotted jet has a better control effect on the suction surface boundary layer,while at large negative angles of attack,the boundary layer of the blade suction surface becomes thinner,the slotting basically fails to reduce losses.关键词
