The flap** or bending of a flexible planar structure in a surrounding fluid flow, which
includes the flap** of flags and the self-streamlining of flexible bodies, constitutes a …

Fluid-induced flag vibrations provide unattended, efficient, low-cost, and scalable solutions
for energy harvesting to power distributed wireless sensor nodes, heat transfer …

We have introduced a modified penalty approach into the flow-structure interaction solver
that combines an immersed boundary method (IBM) and a multi-block lattice Boltzmann …

We establish through numerical simulation conditions for optimal undulatory propulsion for a
single fish, and for a pair of hydrodynamically interacting fish, accounting for linear and …

Experiments are reported on the behavior of two hydrofoils arranged in an in-line
configuration as they undergo prescribed pitching motions over a wide range of phase lags …

A fish may gain hydrodynamic benefits from being a member of a school. Inspired by fish
schools, a two-dimensional simulation was performed for flexible fins propelled in tandem …

The mechanism by which aggregates of active swimmers are formed is an intriguing
problem. In this Letter we show that, for two tandem self-propelled filaments driven by …

The coordinated motion of animal groups through fluids is thought to reduce the cost of
locomotion to individuals in the group. However, the connection between the spatial patterns …

The swimming of aquatic animals and flying of insects and birds have fascinated physicists
and biologists for more than a century. In this regard, great efforts have been made to …

Two tandem flexible flags in viscous flow were modelled by numerical simulation using an
improved version of the immersed boundary method. The flexible flap** flag and the …
