Plant Biology Biophysics Design biomimetics bio-inspired design biomimicry leaf morphology botany heterophylly heat and mass transfer thermal exchanger evapotranspiration evaporative cooling boundary layer building envelopes Interfaces for air-mediated and evaporative transfer help process heat and substances in a variety of technical systems, from electronic to architectural. Because geometry affects the hydraulics, aerodynamic properties and thermal behavior of these devices, their performance can be tuned and passively enhanced through design. For biological interfaces such as plant leaves, geometry is also a determining factor in the exchange of gases, water management and thermal endurance against environmental exposures. Leaf shape, specifically, modulates the leaf’s boundary layer, transpiration, evaporative cooling and convective exchange. In this body of work, design principles extracted from dissipative leaf morphologies were translated into varied evaporative structures (e.g. paper models, ceramic tiles, asphalt shingles). Multiple botanical and design studies were conducted to demonstrate the impact of planar dissection, edge extension, protrusion shape, elongation, scale and dimensionality on evaporative transfer, in controlled and outdoor environments. Overall, this research breaks new interdisciplinary ground and provides further insights into the interpretation of leaves as functionally shaped exchangers. The design outcomes illustrate the potential of leaf-inspired interfaces for thermoregulating the built environment. Ultimately, experimental biomimetics based on design studies with physical models is shown to provide a unique framework for innovating on evaporative technical exchangers. 2020-08-25 English text University of Akron / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=akron15929515707363 http://rave.ohiolink.edu/etdc/view?acc_num=akron15929515707363 restricted--full text unavailable until 2022-08-31 This thesis or dissertation is protected by copyright: all rights reserved.
