Streamline Effect Improvement of Additive Manufactured Airfoil Utilizing Dynamic Stream Control Procedure

Abstract

In the era of fast transport, to create inventive stream ow management solutions that are capable of diminishing the aerodynamic drag of the vehicles, there is a need to modify the ow characteristics over the vehicle by deferring or expelling the position of the ow 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 ow regulations, synthetic jet modules are ingrained at di erent 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 ow 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 nish obtained. By comparing the results, the aerodynamic e ciency showed a signi cant 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 coe cient of lift (Cl) and coe cient of drag (Cd) values showed no progress.

Comparative Study and Aerodynamic Analysis of Rectangular Wing Using High-Lift Systems

“…In recent studies, the increment of the coefficient of the maximum lift was the prime objective, which is intently associated with the avoidance of flow separation. Lift and drag are interrelated and depend upon the design, profile, and other factors [3,4]. An AOA has a remarkable effect on the rise and will increase lift while also increasing drag at the factor in which drag and raise stability stall takes place [5].…”
