Active flow control of airfoils via multi-sweeping jets at ultra low Reynolds numbers
The primary focus is on implementing multiple sweeping jets to eliminate the requirement for high-lift equipment with mechanical components, which are at risk for mechanical failures and increase weight due to redundant control mechanisms.

| Sumario: | The primary focus is on implementing multiple sweeping jets to eliminate the requirement for high-lift equipment with mechanical components, which are at risk for mechanical failures and increase weight due to redundant control mechanisms. This project deals with the investigation of aerodynamic and performance parameters of Airfoils under subsonic flow regimes. This mainly includes the Active flow control techniques such as multi-sweeping jets used in Airfoils that will help us analyse the lift and drag parameters. The jet configurations are studied and modified to reduce viscous drag, improve pressure distribution and interference effects over and below the airfoil, and maximize lift coefficient. Pre and Post-processing stages would include the generation of a complete airfoil design with built-in sweeping jets using Fusion 360. It requires parametric inputs like altering the position of jets in order to calculate the induced drag and thus decrease the drag effects. The use of this open source also results in advanced visualization capabilities that include pressure, velocity distribution, turbulent kinetic energy, and eddy viscosity contours of the airfoil. This analysis and simulation have been carried out using ANSYS Fluent, industryleading fluid simulation software. |
