Mechanics of a plant in fluid flow

FP Gosselin - Journal of Experimental Botany, 2019 - academic.oup.com
Plants live in constantly moving fluid, whether air or water. In response to the loads
associated with fluid motion, plants bend and twist, often with great amplitude. These large …

Morphological plant modeling: unleashing geometric and topological potential within the plant sciences

A Bucksch, A Atta-Boateng, AF Azihou… - Frontiers in plant …, 2017 - frontiersin.org
The geometries and topologies of leaves, flowers, roots, shoots, and their arrangements
have fascinated plant biologists and mathematicians alike. As such, plant morphology is …

Analytical solutions of flow velocity profile based on the morphological response of flexible vegetation

WJ Wang, YF Zhao, S Ren, XB Liu, F Dong, JJ Li… - Journal of …, 2023 - Elsevier

On the scaling of drag reduction by reconfiguration in plants

E De Langre, A Gutierrez, J Cossé - Comptes Rendus Mécanique, 2012 - Elsevier
Slender flexible structures such as plants are deformed by external flow. When the
deformation is significant, this results in a reduction of drag. We give a theoretical value of …

Nonlinear flow response of soft hair beds

J Alvarado, J Comtet, E De Langre, AE Hosoi - Nature Physics, 2017 - nature.com
We are 'hairy'on the inside: beds of passive fibres anchored to a surface and immersed in
fluids are prevalent in many biological systems, including intestines, tongues, and blood …

Hydrodynamics of vegetated channels

J Aberle, J Järvelä - Rivers–physical, fluvial and environmental processes, 2015 - Springer
Hydrodynamics of vegetated channels and streams is a rapidly developing research area,
and this chapter summarizes the current knowledge considering both aquatic and riparian …

An improved Cauchy number approach for predicting the drag and reconfiguration of flexible vegetation

P Whittaker, CAME Wilson, J Aberle - Advances in water resources, 2015 - Elsevier
An improved model to describe the drag and reconfiguration of flexible riparian vegetation is
proposed. The key improvement over previous models is the use of a refined …

A drag force model to incorporate the reconfiguration of full-scale riparian trees under hydrodynamic loading

P Whittaker, C Wilson, J Aberle… - Journal of Hydraulic …, 2013 - Taylor & Francis
This paper investigates the response of full-scale submerged riparian vegetation to
hydrodynamic loading, using data from towing tank experiments of high resolution and …

Flow‐induced reconfiguration of aquatic plants, including the impact of leaf sheltering

X Zhang, H Nepf - Limnology and Oceanography, 2020 - Wiley Online Library
Many aquatic plants are flexible and bend in response to current. This reconfiguration can
reduce the drag on the plant, both by reducing the frontal area and by creating a more …
