Cell wall sculpting and microflows in plants and insects. — •Desislava Todorova1 and Eleni Katifori1,2 — 1Max-Planck Institute for Dynamics and Self-Organization, Göttingen, Germany — 2Department of Physics and Astronomy, University of Pennsylvania, Philadelphia, USA
Remarkably similar types of corrugated architecture have evolved on the internal surfaces of the organs serving for fluid distribution in vascular plants and insects. We focus on examining the relation between the geometric properties of the xylem vessels of plants and the tracheal cells of insects and their functional adaptation for maximizing water flow and gas delivery and exchange, respectively.
We use computational fluid dynamics techniques to study the low Reynolds number flows which naturally occur in such systems and discuss configurations corresponding to optimal functionality.
