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 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.

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.



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

Numerical study of Heat Transfer Enhancement by Deformable Twin Plates in Laminar Heated Channel flow

Fluid-structure interaction (FSI) of thin flexible fins coupled with convective heat transfer has applications in energy harvesting and in understanding functioning of several biological systems. We
