Investigation on 3-D Wing of commercial Aeroplane with Aerofoil NACA 2415 using CFD Fluent

An aerofoil is a cross-section of wing that plays an important role in any aeroplane or aircraft for designing the wings because of wings, lift is generated that holds the aircraft in the air. The design of wing with desired aerodynamic characteristics are most important for aircraft like fighter plane, commercial plane, UAV and MAV . The National Advisory Committee for Aeronautics (NACA) has given a proper definition for aerofoils which help us to select aerofoil for designing the wings of aeroplanes. In this work, NACA 2415 aerofoil has been chosen for designing the 3-D wing of commercial aeroplane because of its high lift to drag ratio at low Reynolds number and Mach number. The 3-D wing has chord length 100mm at root & 18mm at tip and span length 177 mm with 60 dihedral angle. Other wings also drawn with change in design of wing with profile (root) and dihedral angle. Spalart-Allamaras turbulence model is used for better accuracy around boundary wall of wing. Investigation on commercial aeroplane 3-D wing designs are investigated to study the Drag coefficient (CD), Lift coefficient (CL) and Lift-to-Drag ratio (L/D) at various angle of attack. The investigation aims to produce better aerodynamic performance for wing designs to reduce the induced drag formed on wing during the flight operation at take-off; in-turn it will improve the efficiency of the aircraft. The geometry of wing models and meshing are carried out by ANSYS 15 software. The computational simulation is carried out by ANSYS FLUENT at low Mach number (0.23). Flow parameters are measured for different design configurations and compared for efficient design.
