Effect of incident flow unsteadiness on the wake of a bluff body
The paper describes the results of studying the influence of a freestream disturbance localized in time and space on the structure of the wake of a symmetric teardrop-shaped airfoil in the range of angles of attack from −20° to +20°. It is demonstrated that the existence of such a disturbance leads...

Summary: | The paper describes the results of studying the influence of a freestream disturbance localized in time and space on the structure of the wake of a symmetric teardrop-shaped airfoil in the range of angles of attack from −20° to +20°. It is demonstrated that the existence of such a disturbance leads to the suppression of vortex formation at certain angles of attack. Ranges of angles of attack in which the wake structure remains unchanged are found. |
