Aerodynamic Characteristics of Shark Scale-Based Vortex Generators upon Symmetrical Airfoil

A series of wind tunnel tests were carried out to determine the effect shark scale-based vortex generators (SSVG) on a NACA 0015 symmetrical airfoil’s aerodynamic characteristics. Three different sets SSVG with varying geometrical parameters, such as chord length, amplitude, and wavelength, designed fabricated using 3D printing. The models blended baseline airfoil. experiments performed over test airfoil mounted at various angles attack, ranging from 0° 24° in increments 3°, operating range Re = 2 × 105. results revealed that reduced drag increased maximum coefficient lift (CLmax), thereby enhancing overall performance. offered noteworthy benefits by effectively altering flow causing significant spanwise variation properties. Additionally, attempts made identify optimum chordwise location blend for effective use.
