Summary

How can wind impact on and interact with plant life? This natural phenomenon has been a field of investigation for many scientific disciplines over the last decade or so. In order to provide answers, Emmanuel de Langre and Pascal Hémon, researchers at the hydrodynamics laboratory of the École Polytechnique Paris Saclay, carry out a first full-scale experiment at the Jules Verne wind tunnel in Nantes.
Biomechanicians and aerodynamic specialists or plant biologists have placed a tree in a wind tunnel to study the movement of its leaves subjected to different variations of artificial wind. A cine-camera device (infrared and high-speed) will record the movement of the leaves from various angles. This so-called fine experiment is carried out to collect a maximum of data, measurements and information with the purpose of creating models.
