Performance of Supercritical Aerofoil using the CO-Flow Jet

Abstract

The paper aims to evaluate the behavior of a supercritical aerofoil at cruise conditions. The simulation study was performed using the pressure-based solver with the turbulence model of Spalart Allmaras at cruise conditions level. The obtained data proved that the supercritical aerofoil using the co-flow jet method increases the lift coefficient by 43% and lowers the drag by 3% compared to the regular aerofoil. The proposed work's novelty is the co-flow jet's design over a transonic aerofoil by introducing the design behind the mid of chord, which was used to evaluate and improve the performance through the jet velocity concept of a supercritical aerofoil. In traditional methods, the injection suction is positioned close to the leading and trailing edges, respectively. The suggested method can be used in commercial, Military, and wind turbine-related applications.
