The objective of this project is to study and analyze the suppression mechanism of rollover vortices on airframes. Effectof rollover vortices on airframes causes major problems for many flying vehicles. Some of the problems are vibrations of wing,flow separation, increases induced drag, and decreased lift of wing. So it is important to suppress the rollover vortices onairframe. Lot of active techniques and methods are available which are very complex to design and difficult to implement. So it isnecessary to develop some passive techniques which are easy to design and implement.The rollover vortices are difficult to determine directly. But it can be find indirectly by analyzing turbulence level in theflow. Vortices affect mostly on the wing. So NACA 2424 wing of span 0.6m and chord 0.15m is meshed and analyzed incommercial CFD software packages. Wedges, notches, slits and booms are the modifications done on the wing to suppress thevortices as taken from literatures.
