Flutter analysis and wind-tunnel experiments of a flat plate suspended by wires
Nihon Kikai Gakkai ronbunshu, 2023 In the construction work, flat plates for building materials are transported by a suspension mechanism using wires in air flow. Then, a flutter could be caused to the suspended plates due to the interaction between plate motion and fluid flow.

Stereo PIV measurements of vortex behavior produced by a pitch-oscillating discoid airfoil
Journal of Fluid Science and Technology, 2014 Flying animals and insects flap their wings using a combination of pitching and heaving oscillations. Unsteady fluid forces presumably play an important role in the flight mechanism, and also in the propulsive force of swimmers performing the front crawl.
