Abstract: The primary investigation in the aerodynamics is to study how the objects fly in the air. Study of lift and drag forces are the important forces to be considered in the aircraft wing design. In this research we focus on the comprehensive study of tapered 3D unsymmetrical airfoil wing. Tapered wing is modeled in CATIA V5 considering NACA 64-210 at the tip and NACA 64-215 at the root. Computational Fluid Dynamics is carried out using ANSYS Fluent R20. Reynolds number 5.8x106(50m/s) is considered, which resembles the subsonic speed. Pressure and velocity distribution over the 3D tapered unsymmetrical wing surface is studied. Lift and drag forces are determined at various angles of attack, the results are tabulated and graphs are drawn for lift force versus different angles of attack and drag force versus different angles of attack. Study reveals that results clearly justify the Ludwig Prandtl boundary layer theory where pressure and velocity are inversely proportional.
