TL;DR: In this paper, a 3D oscillatory flow is constructed from uncorrelated 2D snapshots of particle image velocimetry data, using proper orthogonal decomposition, a phase-averaging technique and an azimuthal symmetry associated with helical structures.

TL;DR: In this article, a growing recirculation bubble between the main jet and the attachment wall is identified as an underlying mechanism that causes a main jet to oscillate, and a proper orthogonal decomposition was applied to random flow field snap shots for phase reconstruction of one oscillation cycle.

TL;DR: In this paper, an experimental investigation of separation and circulation control was carried out using corona discharge as well as dielectric barrier discharge actuators at typical micro air vehicle (MAV) Reynolds numbers.

TL;DR: In this article, the utility of constant blowing as an aerodynamic load control concept for wind turbine blades was explored experimentally, and a NACA 0018 airfoil model equipped with control slots near the leading edge and at mid-chord was investigated initially under quasi-static conditions at Reynolds numbers ranging from 1.25·105 to 3.75·105.

TL;DR: In this article, the internal and external flow field of a fluidic oscillator with two feedback channels were examined experimentally within the incompressible flow regime, and it was shown that the oscillation mechanism is based on fluid feeding into a separation bubble between the jet and mixing chamber wall which pushes the jet to the opposite side.
