These devices are made up of simple sheet metal plates which are placed at upstream of the separated area with a predetermined cross angle with the flow. The oldest and the simplest means of flow control for separated areas is using mechanical devices called vortex generators (VGs). Keywords: Energy, temperature, computational fluid dynamics, aerofoil, wing, heat transfer, turbulence, aerodynamics.įlow separation occurs in various flow conditions and at various locations around an aircraft, especially flow separation over the wing is of serious concern as it directly affects the aircraft performance. All computations will be carried out using the RANS modeling which is available in commercially CFD package. The best shape and location of the VGs for each of the flow regimes will be determined. The analysis has to be carried out at subsonic (M=0.5), transonic (M=1.0) and supersonic (M=2.0) flow regimes. The drag and lift characteristics of each shape and locations of VGs have to be studied. Complete three dimensional results to be for the flow over wing equipped with Vortex Generators with various shapes and locations over the wing.
The project work (report) deals with the CFD analysis of VGs on a wing. Vortex Generators are highly efficient aerodynamic devices that are used widely in both external and internal aerodynamics as means of flow control.
Aim is to understand the flow complexity and how to improve these two parameters with the help of vortex generator kind of devices. In order to reduce the drag and improve lift forces to achieve better performance with less power consumption for NACA 64215, which is newly developed aerofoil wing, drag and lift forces are very critical parameters to optimize the performance.
