Flexible slender structures are ubiquitous in biological systems and engineering
applications. Fluid-structure interaction (FSI) plays a key role in the dynamics of such …

We revisit the grid-point requirement estimates in Choi and Moin [“Grid-point requirements
for large eddy simulation: Chapman's estimates revisited,” Phys. Fluids 24, 011702 (2012)] …

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 …

A detailed flow field behind a stationary square cylinder with attached rigid and flexible
splitter plates has been studied using particle image velocimetry, constant temperature …

Inspired from deformable caudal fins, continuous bending motion is utilized to improve the
propulsive performance of flapping foils for underwater vehicles. The propulsive …

The present study investigates the mechanisms of wake-induced flow dynamics in tandem
National Advisory Committee for Aeronautics 0015 flapping foils at low Reynolds number of …

Experiments are reported on the performance of a pitching and heaving two-dimensional foil
in a water channel in either continuous or intermittent motion. We find that the thrust and …

The flapping dynamics of vertically clamped three-dimensional flags in a Poiseuille flow was
studied numerically by using the immersed boundary method. First, the flapping dynamics of …

The effect of non-uniform chordwise stiffness distribution on the self-propulsive performance
of three-dimensional flexible plates is studied numerically. Some typical stiffness …

In this study, numerical simulations are employed to investigate the hydrodynamic
performance and wake topology of a swimming Rhinoptera javanica. The study is motivated …
