Description

This research aims with the advent of advancements in the evaluation of liquids and gases, Computational Fluid Dynamics technique has found widespread applications in various fields including aerodynamics. The wing is an important aerodynamic feature that has seen modifications in recent years to suffice the growing need for a greater maximum lift coefficient (CL). Existing designs make use of greater lift gadgets such as flaps and slats these are enhancers of the lift force and are at large used as attachments on the main wing body. This project investigates the 4 digit NACA 2412 airfoil improved using a 5 digit NACA 24012 Fowler flap. The two airfoils are set at particular angles to each other with an overlap and gap distance. Optimization of the flap deflection angle ?flap, the horizontal gap, and overlap between the flap and wing is simulated using CFD tools and the obtained coefficients of lift and drag experimentally validated to determine the optimum model configurations. It is noted that the coefficients of lift and drag increase to a certain point as the flap deflection angle increases. However, beyond a certain angle, CL drops. This new multi-element wing configuration will find its applications in low-speed aircraft used for general aviation and to reduce the need for longer runways. TJPRC Pvt. Ltd.
