Stall Characteristics Study of Aircraft Wing with Fence

Abstract

In the present work, we studied aerodynamic characteristics of lift, drag and stalling characteristics. . The accumulative stalling angle is a greater mission in the wing. But our examination is primarily focused on the behavior of lift. A computational study, to improve the stall characteristics of NACA 0012 wing at high angles of attack, with and without fence configuration is done here. Wing fences, also known as boundary layer fences and potential fences are fixed aerodynamic devices attached to aircraft wings. Single Fence was fixed in the exactly middle of the wing span and two fences are fixed at 25 percentage of wing span from their corresponding wing tip. The main aim of the project is to improve the lift and stalling angle. A rectangular wing with different angles of attack is used. Modeling was done in CATIA V5 R20 and meshing and analyzing was taken in ANSYS workbench and CFX. Then the graph is drawn for CL and CD for various angles of attack and various models.
