“…Robert Jones [14] described the advantages of single winglets for small transports, on which they can provide 10% reduction in induced drag compared with elliptical wings. Winglets are being incorporated into most new transports [15], the Boeing and McDonnell Douglas airliners, and the McDonnell Douglas military transport. [16] The induced drag of a non-planar system can be lower than that of a planar system of the same lift and span.…”

The present article is an effort to examine the potential of multiple winglets to reduce the induced drag of the aerodynamic surface. The advantages of using multiple winglets include reduction of induced drag, increased L/D and improved performance of the Wind turbine. Computational Fluid Dynamics is utilized as to approach the effects of multiple winglets with NACA 24012 airfoil section for untwisted, rectangular wing. The testing of configurations is done at Reynolds number 290,000. FLUENT solver incorporated in ANSYS used for the numerical investigation of the steady flow over the wing. A substantial improvement in lift curve slope occurs with dihedral spread of the winglets. The dihedral spread also distributes the tip vortices.
