Fishes have learned how to achieve outstanding swimming performance through the
evolution of hundreds of millions of years, which can provide bio-inspiration for robotic fish …

Aquatic organisms are known for their ability to generate efficient propulsion with low energy
expenditure. While existing research has sought to leverage bio-inspired structures to …

Natural swimmers usually perform undulations to propel themselves and perform a range of
maneuvers. These include various biological species ranging from microsized organisms to …

Symmetric flap** foils are known to produce deflected jets at high frequency–amplitude
combinations even at a zero mean angle of attack. This reduces the frequency range of …

Tandem flap**-wing micro aerial vehicles, which are inspired by dragonflies, are unique
in that they have two pairs of wings, and this could increase their maneuverability during …

To optimize flap** foil performance, in the current study we apply deep reinforcement
learning (DRL) to plan foil non-parametric motion, as the traditional control techniques and …

Tandem flap** foils can achieve high propulsive efficiency through beneficial wake
interactions. Present study investigates the propulsive performance of tandem foils through …

Wake evolution of an oscillating foil with combined heaving and pitching motion is evaluated
numerically for a range of phase offsets (pairs observed consistently for oscillating foils with …

Three-dimensional wake of an oscillating foil with combined heaving and pitching motion is
numerically evaluated at a range of chord-based Strouhal number (0.32≤ S tc≤ 0.56) and …
