3D Simulation of Wing fitted with Vortex Generators

Abstract

This paper uses wing characteristics from the Half Scale Unmanned Arial Vehicles (UAV) designed by Defence Technology Institute (DTI). It also demonstrates results from both plain wing and wing fitted with VGs simulation using a commercial Computational Fluid Dynamics (CFD) program. VGs designing processes (sizing and installed position) are also designed according to historical data. Furthermore, six different VGs configurations are tested to find effects to the wing aerodynamics. Stall angle, lift coefficient (CL), and drag coefficient (CD) are obtained through CFD, and they will be discussed.
