Two tandem cylinders of different diameters in cross-flow: effect of an upstream cylinder on wake dynamics
TL;DR: In this article, the authors provide a systematic experimental study on the wake of two tandem cylinders of unequal diameters, including the time-mean drag coefficient, fluctuating drag and lift coefficients, and the Strouhal number.

A review of energy extraction from wind and ocean: Technologies, merits, efficiencies, and cost
TL;DR: In this paper , the authors focus on energy harvesting techniques of onshore and offshore (both fixed and floating foundations) wind energy as well as ocean energy including ocean thermal energy, wave energy, tidal energy, salinity gradient energy, and bio-inspired energy harvesting.

Vortex shedding from tandem cylinders
TL;DR: In this article, an experimental investigation is conducted on the flow properties of tandem cylinders for ranges of diameter ratio d/D = 0.25-1.0, spacing ratio L/d = 5.5-20, and Reynolds number Re =0.8 × 104-2.42 × 104, where d and D are the diameters of the upstream and downstream cylinders, respectively, L is the distance from the upstream cylinder center to the forward stagnation point of the downstream one.

Experimental study of a passive control of airfoil lift using bioinspired feather flap.
TL;DR: This paper presents a systematic experimental investigation on a passive flow control of a NACA0012 airfoil using real feather flap which is installed on the suction or pressure surface to understand the origin of the aerodynamic benefits introduced by the feather flap.

Post-stall flow control using a sawtooth plasma actuator in burst mode
TL;DR: In this article, a vortex-generator type plasma actuator (VG-PA) was used to control post-stall airfoil aerodynamics using a burst mode (BM) at a Reynolds number Re of 0.77 × 105.
