Aerodynamic Analysis of S809 Airfoil: A Stall Validation with RANS k-ω Turbulence Models

This study examines the aerodynamic efficacy of the S809 airfoil at six angles of attack: ?14.23°, ?5.15°, 0°, 5.13°, 9.22°, and 10.21°. It uses steady two-dimensional RANS with two closures: k–? SST (Menter) and k–? Standard. It also checks the results against wind-tunnel data from NREL. We digitized experimental pres...
