Investigation of several passive and active methods for turbulent flow separation control
TL;DR: In this article, the relative performance of several passive and active methods for controlling two-dimensional turbulent separated flow associated with a curved backward-facing ramp was investigated at low speeds, and the results indicated that submerged vortex generators, vortex generator jets, elongated arches at +-alpha, and large-eddy breakup devices at + -alpha placed near the baseline separation location reduce flow separation and increase pressure recovery.

Comparative Study of Control Techniques for Two-Dimensional Low-Speed Turbulent Flow Separation
TL;DR: In this article, the relative performance of several passive and active methods for controlling two-dimensional turbulent separated flow associated with a curved backward-facing ramp was investigated at low speeds, and it was shown that Spanwise cylinders reduce flow separation but decrease pressure recovery downstream, whereas elongated arches and huge-eddy breakup devices (LEBU's) with α ≤ 0° have no significant effect in reducing separation.
