In the era of fast transport, to create inventive stream flow management solutions that are capable of diminishing the aerodynamic drag of the vehicles, there is a need to modify the flow characteristics over the vehicle by deferring or expelling the position of the flow partition. e objective of this study involves the parameterized design of an airfoil utilizing the Bezier curve technique with the assistance of the simulation program. For flow regulations, synthetic jet modules are ingrained at different percentages of the chord to manage the stall characteristics. e parametrization system, combined with the stream control method, can give a much better insight into flow re-energization and pave some way for the reduction of the wake. Digital fabrication technique (3d printing or Rapid Prototyping method) is used to fabricate the end product for aerodynamic testing. e comparative outcome showed a reduction in drag at certain angles of attack due to the surface finish obtained. By comparing the results, the aerodynamic efficiency showed a significant rise of 13.05% at lower angles of attack when compressed gas was used in the synthetic jet closer to the frontier edge of the airfoil. Near the stall angle of attack, the coefficient of lift (Cl) and coefficient of drag (Cd) values showed no progress. 1. Introduction Diminishment of drag over an airfoil is dealt with in two stages. e configuration file is described in the right detail first, and then the flow control device is added later. ere are diverse holes available to model the rib profile curve. ey are adjusted beneath a roof referred to as parameterization procedures. Parameterization tech- niques include Bezier curves, Class-Shape function Transformation, Hicks-Henne “Bump” function and polynomial method, Ferguson curve, and ? 3 [1]. Each parameterization strategies have its own recompenses, Selection of the exact method guarantees the smoothness of the 2d bend, the more parameters the optimization process could seek out more aerofoil shapes. On the other hand, with more design parameters, it would be costly to seek design space unwanted curves. e parameterization technique used here is Bezier curve which comes with the disadvantage of no local control. With this change, the position of a control point affects the entire curve. Bezier curve parameterization is a spline curve with a parametric methodology (u, t) that can be used to more precisely model a 2D aerofoil. e advantage of the Bezier curve over others is the ease of computation, steadiness at the lower degrees of control points, and a Bezier curve can be turned and interpreted by performing operations on the control points, which comes with a disadvantage of no local control. With this change, the position of a control point affects the entire curve.
