Interaction of vortex streets with a downstream wing

Effect of Wing Sweep Angle on the Vortex Interaction of a Tail-Wing Configuration

The goal of this investigation is to study the effect of wing sweep angle on the horizontal wing-body- tail configurations in subsonic flow. For this purpose, a series of wind tunnel tests were conducted on a model having a moveable horizontal tail and a wing planform with different sweep angles. Tests were performed at different tail deflection angles. Static surface pressure distribution over...

Vortex Streets on a Sphere

Experimental Study of Vortex Shapes behind a Wing Equipped with Different Winglets

An extensive experimental study is conducted to examine effects of different winglet-shapes and orientations on the vortex behind a wing, static surface pressure over the wing, and wing wake of a swept wing at various angles of attack. Four types of winglets, spiroid (forward and aft), blended, and winggrid are used in this investigation. Wing static surface pressure measurements are obtained f...

Studies of Two-Dimensional Vortex Streets

Periodic vortex streets, often considered as a model for the organized structures observed in the wake of two-dimensional (2D) bluff bodies, are revisited. After the generation of the shear layers the formation of the vortices is mainly an inviscid process. An intrinsic scaling for the formation of vortex streets is found based on the invariants of motion for 2D inviscid flows; namely the kinet...
