Drag reduction of a blunt body through reconfiguration of rear flexible plates

We investigate the quasi-static reconfiguration of rear parallel flexible plates on the drag coefficient of a blunt body. The drag coefficient, plates deformation, and main features of the turbulent

On the distinct drag, reconfiguration and wake of perforated structures

Using especially designed laboratory experiments, we demonstrate that the flow-driven deformation of sufficiently porous, wall-mounted, flexible plates can exhibit positive Vogel exponent $V$, i.e.

On the Dynamics of Flexible Plates under Rotational Motions

The reconfiguration of low-aspect-ratio flexible plates, required power and induced flow under pure rotation were experimentally inspected for various plate stiffness and angular velocities ω.

Flow-induced motions of flexible plates: fluttering, twisting and orbital modes

The unsteady dynamics of wall-mounted flexible plates under inclined flows was fundamentally described using theoretical arguments and experiments under various Cauchy numbers

Modelling flow-induced reconfiguration of variable rigidity aquatic vegetation

ABSTRACT Aquatic vegetation is an important component of coastal and riverine environments and plays a significant role in shaping their evolution. The extent and nature of eco-hydraulic interaction

This review paper surveys the mechanics of FSI on individual plants and covers the dynamical phenomena of wave action, flutter, and vortex-induced vibrations.



Drag reduction of flexible plates by reconfiguration

Through an extensive and systematic experimental investigation of two geometries of flexible plates in air, it is shown that a properly defined scaled Cauchy number allows collapsing all drag

Drag reduction through self-similar bending of a flexible body

This work uses a flexible fibre immersed in a flowing soap film to measure the drag reduction that arises from bending of the fibre by the flow, and uses a model that couples hydrodynamics to bending to predict a reduced drag growth compared to the classical theory.

Large coupled bending and torsional deformation of an elastic rod subjected to fluid flow

How flexibility induces streamlining in a two-dimensional flow

Recent work in bio-fluid dynamics has studied the relation of fluid drag to flow speed for flexible organic structures, such as tree leaves, seaweed, and coral beds, and found a reduction in drag

Scaling laws for drag of a compliant body in an incompressible viscous flow

Motivated by an important discovery on the drag scaling law (the 4/3 power law) of a flexible fibre in a flowing soap film by Alben et al. (Nature vol. 420, 2002, p.479) at high Reynolds numbers

Bending of elastic fibres in viscous flows: the influence of confinement ‡

Abstract We present a mathematical model and corresponding series of microfluidic experiments examining the flow of a viscous fluid past an elastic fibre in a three-dimensional channel. The fibre’s
