A numerical investigation was carried out to analyze the interactions between semi-active
tandem flapping foils at various tandem distances with a chord-based Reynolds number of …

In nature, insects with their forewings and hindwings undergoing small-gap flapping motion
experience strong aerodynamic interaction. Conventional studies mainly focus on the …

Collective movements are common in nature, such as the swimming of fish schools and the
flight of birds in formation. The aero/hydrodynamic performance of such movements is a …

We study a collection of polar self-propelled particles or polar flock on a two dimensional
substrate involving birth and death. Most of the previous studies of polar flock with birth and …

Active flow control was applied to a tandem configuration of two SD7003 airfoils. The
tandem configuration consisted of an upstream airfoil (forefoil) with a pitching motion at a …

Dragonfly-like flapping wings and foils take an in-line arrangement and their performance is
strongly affected by the wing–wing interaction. In this study of tandem pitching-plunging foils …

In this work, we designed and characterized a passive structural wing actuation setup that
was able to realistically mimic the flapping and pitching kinematics of dragonflies. In this …

Motivated by the energy efficient locomotion by flock of birds and school of fish to develop
biomimetic systems, the current study studies the propulsive performance of the tandem …

An investigation is conducted on the propulsion performance of semi-active flapping foils in
tandem configuration of the wave glider, considering different vortex effects and tandem …
