Abstract

The objective of this project is to delay the flow separation over the symmetrical airfoil by placing the synthetic jet actuator. A synthetic jet actuator is a device which moves a fluid in and outside a cavity through a small orifice and also it will maximize the aerodynamic performance of the airfoil. The aerodynamic characteristic of the airfoil have been compared in detail at different angles of attack, for the case with and without adoption of synthetic jet. This control device is having zero mass flux active flow control device. The external flow around the airfoil will be determined by using numerical approach. By changing the angle of attack we can analyse how the separation of flows are varied. Results of this study demonstrated the actuator effectiveness on overall aerodynamic performance and show consistent trends with high-order Computational Fluid Dynamics (CFD).
