Design With Constructal Theory

eBook Download

BOOK EXCERPT:

Design course on the universal principle of configurations in nature and engineering-the constructal law Design with Constructal Theory offers a revolutionary new approach based on physics for understanding and predicting the designs that arise in nature and engineering, from the tree and the forest to the cooling of electronics, urban design, decontamination, and vascular smart materials. This book shows how you can use the method of constructal theory to design human-made systems in order to reduce trial and error and increase the system performance. First developed in the late 1990s, constructal theory holds that flow architecture arises from the natural evolutionary tendency to generate greater flow access in time and in flow configurations that are free to morph. It unites flow systems with solid mechanical structures, which are viewed as systems for the flow of stresses. Constructal theory unites nature with engineering, and helps us generate novel designs across the board, from high-density packages to vascular materials with new functionalities (self-healing, self-cooling), and from tree-shaped heat exchangers to svelte fluid-flow and solid structures. Design with Constructal Theory starts with basic principles and then shows how these principles are applied to understanding and designing increasingly complex systems. Problems and exercises at the end of each chapter give you an opportunity to use constructal theory to solve actual design problems. This book is based on a design course developed by the two authors for upper-level undergraduates and graduate students at Duke University and other universities all over the world. With the authors' expert guidance, students and professionals in mechanical, civil, environmental, chemical, aerospace, and biomedical engineering will understand natural systems, and then practice design as science, by relying on constructal strategies to pursue and discover novel and effective designs.

Constructal Law And The Unifying Principle Of Design

eBook Download

BOOK EXCERPT:

Design happens everywhere, whether in animate objects (e.g., dendritic lung structures, bacterial colonies, and corals), inanimate patterns (river basins, beach slope, and dendritic crystals), social dynamics (pedestrian traffic flows), or engineered systems (heat dissipation in electronic circuitry). This “design in nature” often takes on remarkably similar patterns, which can be explained under one unifying Constructal Law. This book explores the unifying power of the Constructal Law and its applications in all domains of design generation and evolution, ranging from biology and geophysics to globalization, energy, sustainability, and security. The Constructal Law accounts for the universal tendency of flow systems to morph into evolving configurations that provide greater and easier access over time. The Constructal Law resolves the many and contradictory ad hoc statements of “optimality”, end design, and destiny in nature, such as minimum and maximum entropy production and minimum and maximum flow resistance, and also explains the designs that are observed and copied in biomimetics. Constructal Law and the Unifying Principle of Design covers the fundamentals of Constructal Theory and Design, as well as presenting a variety of state-of-the-art applications. Experts from the biological, physical and social sciences demonstrate the unification of all design phenomena in nature, and apply this knowledge to novel designs in modern engineering, such as vascularization for self-healing and self-cooling materials for aircraft, and tree fins and cavities for heat transfer enhancement.

Thermohydrodynamic Programming And Constructal Design In Microsystems

eBook Download

BOOK EXCERPT:

Thermohydrodynamic Programming and Constructal Design in Microsystems explains the direction of a morphing system configuration that is illustrated by life evolution in nature. This is sometimes referred to as the fourth law of thermodynamics, and was first applied in thermofluidic engineering, with more recent applications in physics and biology. The book specifically focuses on synthetic modeling and constructal optimization in the design of microsystemic devices, which are of particular interest to researchers and practitioners in the sphere of micro- and nanoscale physics, a mechanistically deviation from conventional theory. The book is an important reference resource for researchers working in the area of micro- and nanosystems technology and those who want to learn more about how thermodynamics can be effectively applied at the micro level. - Explains how the application of constructal theory can lead to more effective microsystems design - Offers an introduction to the fundamentals and application to different flow and heat/mass transport systems - Bridges the gap between theoretical design and optimization, from a practical point-of-view

Critique Of Constructal Theory

eBook Download

BOOK EXCERPT:

Constructal theory has been extensively used to analyze and optimize many different shapes and structures in both living and non-living systems. It is generally considered to be a law that could govern the evolutions of shapes and structures in biology, physics, technology, and social organization. Accordingly, it seems that the constructal method is suitable for designing and analyzing all kinds of shapes and structures in the world. However, in most cases, the details for its applications were not carefully checked, meaning that it was often incorrectly applied, and that many unreasonable or inaccurate results were provided. This book systematically reviews and checks the applications of constructal theory in street design, economics, heat transfer optimization, flow systems, and explanations of natural structures and social phenomena. Every detail of the models, methods, optimizations, applications, results and conclusions is analysed, with careful consideration of theoretical derivations and typical examples. Accordingly, the problems and mistakes in the applications of the theory are directly pointed out and discussed in detail. The abuse and limitation of the constructal approach are also discussed. In many cases, it is shown that the theory has significant flaws and is even not applicable in certain circumstances. As constructal theory is widely used in the analysis and design of shapes and structures, this book will be essential for scientists, researchers, engineers, teachers, postgraduates and undergraduates in the fields of structure analysis, design and optimization in physics, biology, flow dynamics, heat transfer and thermodynamics.

Constructal Human Dynamics Security And Sustainability

eBook Download

BOOK EXCERPT:

Globalization, security infrastructure and energy sustainability can be designed based on a scientific principle. In this book, these objectives are approached based on constructal theory, which means to design such projects as global ‘flow’ architectures that are ‘alive’ with movement of personnel, equipment, information, education, etc. Constructal Human Dynamics, Security and Sustainability highlights the progress made during the NATO Advanced Research Workshop held in Évora, Portugal in May 2008. This workshop brought together social scientists with physicists, engineers and biologists. Together they addressed main topics such as human dynamics viewed as natural phenomena of design generation, flow networks for distribution and collection, large-scale construction projects (e.g., airports, waste storage), logistics, decontamination, energy supply routes, distributed energy systems, water resources management, environmental security sustainability and globalization. The chapters selected for this book represent the interdisciplinary approach and team atmosphere that emerged in Évora.
