Evidence of large scale time dependent flow in the wing-wall interaction wake
Abstract
Results are presented from a wind tunnel experiment conducted to measure characteristics of turbulent large scale, time-dependent organized motion of the flow generated by a wing-wall junction. The motion is possibly associated with the known horseshoe root vortex. The experimental data provide qualitative proof that the structures exist, and that they exhibit out-of-phase motions at mirror-image positions across the plane of symmetry.
