Bio-Inspired Hydrodynamic Dampening Array

Design and prototype a modular, passive-actuated flow control device capable of mitigating vortex-induced vibration (VIV) on a cylindrical pylon submerged in high-velocity current. The mechanism must utilize flexible, biomimetic materials to adjust its surface topology in response to Reynolds number variations, thereby minimizing drag coefficient without external energy input. Validate the efficiency of your dampener by measuring the suppression of transverse oscillations in a scaled water-channel simulation.

Materials: Flexible silicone sheeting, thin high-density polyethylene strips, waterproof structural adhesive, weighted fishing line, a deep plastic storage bin, and a variable-speed submersible aquarium pump.
