摘要：
Based on the k-ω SST turbulence model，the dynamic stall process of DU91-W2-250 airfoil segment with vortex generators （VGs）installedat different spacing （z）and installation angle （αvg） is numerically studied. The airfoil segment performs a typical sinusoidal pitch oscillation motion，and the influence of the VGs installation parameters on the flow control effect of the airfoil segment is investigated. It is found that changing the z has little effect on the aerodynamic performance，while changing the αvg has great effect；when z is from 6 to 8 mm，and αvg is from 13.4° to 16.4°，the VGs have a good effect on improving the aerodynamic performance of the airfoil segment. The strength of streamwise vortices is a major factor affecting the flow control effect of VGs. © 2023 Science Press. All rights reserved.
