Biomimicry for Materials, Design and Habitats: Innovations and
Applications and is a survey of the recent work of recognized
experts in a variety of fields who employ biomimicry and related
paradigms to solve key problems of interest within design, science,
technology, and society. Topics covered include innovations from
biomimicry in materials, product design, architecture, and
biological sciences. The book is a useful resource for educators,
designers, researchers, engineers, and materials scientists, taking
them from the theory behind biomimicry to real world applications.
Living systems have evolved innovative solutions to challenges that
humans face on a daily basis. Nonlinear multifunctional systems
that have a symbiotic relationship with their environment are the
domain of nature. Morphological solutions for buildings inspired by
nature can be used for skins, surfaces, and structures to
facilitate environmental adaptation of buildings to increase
occupant comfort and reduce energy demands. Birds can teach us to
produce novel structures, 3D printing can be informed by oysters
and mussels, and mycelium may show us the way to fabricate new
biocomposites in architecture. Therefore, it is in nature that we
seek inspiration for the solutions to tomorrow's challenges.
The solutions to technical challenges posed by flight and space
exploration tend to be multidimensional, multifunctional, and
increasingly focused on the interaction of systems and their
environment. The growing discipline of biomimicry focuses on what
humanity can learn from the natural world. Biomimicry for
Aerospace: Technologies and Applications features the latest
advances of bioinspired materials-properties relationships for
aerospace applications. Readers will get a deep dive into the
utility of biomimetics to solve a number of technical challenges in
aeronautics and space exploration. Part I: Biomimicry in Aerospace:
Education, Design, and Inspiration provides an educational
background to biomimicry applied for aerospace applications. Part
II: Biomimetic Design: Aerospace and Other Practical Applications
discusses applications and practical aspects of biomimetic design
for aerospace and terrestrial applications and its
cross-disciplinary nature. Part III: Biomimicry and Foundational
Aerospace Disciplines covers snake-inspired robots, biomimetic
advances in photovoltaics, electric aircraft cooling by bioinspired
exergy management, and surrogate model-driven bioinspired
optimization algorithms for large-scale and complex problems.
Finally, Part IV: Bio-Inspired Materials, Manufacturing, and
Structures reviews nature-inspired materials and processes for
space exploration, gecko-inspired adhesives, bioinspired automated
integrated circuit manufacturing on the Moon and Mars, and smart
deployable space structures inspired by nature.
Unsteady 3-D RANS simulations have been performed on a highly
loaded transonic turbine stage and results are compared to steady
calculations as well as to experiment. A low Reynolds number
k-epsilon turbulence model is employed to provide closure for the
RANS system. A phase-lag boundary condition is used in the
tangential direction. This allows the unsteady simulation to be
performed by using only one blade from each of the two rows. The
objective of this work is to study the effect of unsteadiness on
rotor heat transfer and to glean any insight into unsteady flow
physics. The role of the stator wake passing on the pressure
distribution at the leading edge is also studied. The simulated
heat transfer and pressure results agreed favorably with
experiment. The time-averaged heat transfer predicted by the
unsteady simulation is higher than the heat transfer predicted by
the steady simulation everywhere except at the leading edge. The
shock structure formed due to stator-rotor interaction was
analyzed. Heat transfer and pressure at the hub and casing were
also studied. Thermal segregation was observed that leads to the
heat transfer patterns predicted by steady and unsteady simulations
to be different.
