Download or read book Biophysics of Insect Flight written by N. Chari and published by Springer Nature. This book was released on 2022-01-04 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book basically involves the study of flight parameters, wing beat frequency, moment of inertia, and wing movements for developing various aerodynamic forces which have been calculated. The book is intended for biologists, physicists, nanotechnologists, and aerospace engineers. Resilin, an elastic polymer (4 λ) which is present at the base of insect, plays a major role in Neurogenic and Myogenic insect flyers and influences the physiology of flight muscles. Leading edge vortex (LEV) is a special feature of insect flight. Insect wings have stalling angle above 60 degrees as compared to a man-made aeroplane stalling angle which is 16 degree. Reynolds number, the knowledge of LEV, and detailed study of moment of inertia help in developing flapping flexible wings for micro-aerial-vehicles. This book serves as an interface between biologists and engineers interested to develop biomimicking micro-aerial-vehicles. The contents of this book is useful to researchers and professionals alike.

This book was released on 2012-12-06 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of environmental biophysics probably began earlier in man's history than that of any other science. The study of organism-environment interaction provided a key to survival and progress. Systematic study of the science and recording of experimental results goes back many hundreds of years. Ben jamin Franklin, the early American statesman, inventor, printer, and scientist studied conduction, evaporation, and radiation. One of his observations is as follows: My desk on which I now write, and the lock of my desk, are both exposed to the same temperature of the air, and have therefore the same degree of heat or cold; yet if I lay my hand successively on the wood and on the metal, the latter feels much the coldest, not that it is really so, but being a better conductor, it more readily than the wood takes away and draws into itself the fire that was in my skin. 1 Franklin probably was not the first to discover this principle, and certainly was not the last. Modem researchers rediscover this principle frequently in their own work. It is sometimes surprising how slowly progress is made. Progress in environmental biophysics, since the observa tions of Franklin and others, has been mainly in two areas: use of mathematical models to quantify rates of heat and mass transfer and use of the continuity equation that has led to energy budget analyses.

Download or read book Why Don't Jumbo Jets Flap Their Wings? written by David Alexander and published by Rutgers University Press. This book was released on 2009-06-02 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: What do a bumble bee and a 747 jet have in common? It’s not a trick question. The fact is they have quite a lot in common. They both have wings. They both fly. And they’re both ideally suited to it. They just do it differently. Why Don’t Jumbo Jets Flap Their Wings? offers a fascinating explanation of how nature and human engineers each arrived at powered flight. What emerges is a highly readable account of two very different approaches to solving the same fundamental problems of moving through the air, including lift, thrust, turning, and landing. The book traces the slow and deliberate evolutionary process of animal flight—in birds, bats, and insects—over millions of years and compares it to the directed efforts of human beings to create the aircraft over the course of a single century. Among the many questions the book answers: Why are wings necessary for flight? How do different wings fly differently? When did flight evolve in animals? What vision, knowledge, and technology was needed before humans could learn to fly? Why are animals and aircrafts perfectly suited to the kind of flying they do? David E. Alexander first describes the basic properties of wings before launching into the diverse challenges of flight and the concepts of flight aerodynamics and control to present an integrated view that shows both why birds have historically had little influence on aeronautical engineering and exciting new areas of technology where engineers are successfully borrowing ideas from animals.

Available in PDF, EPUB and Kindle. Book excerpt: Both a landmark text and reference book, Steven Vogel's Life in Moving Fluids has also played a catalytic role in research involving the applications of fluid mechanics to biology. In this revised edition, Vogel continues to combine humor and clear explanations as he addresses biologists and general readers interested in biological fluid mechanics, offering updates on the field over the last dozen years and expanding the coverage of the biological literature. His discussion of the relationship between fluid flow and biological design now includes sections on jet propulsion, biological pumps, swimming, blood flow, and surface waves, and on acceleration reaction and Murray’s law. This edition contains an extensive bibliography for readers interested in designing their own experiments.

Download or read book Unsteady Aerodynamics and Propulsive Characteristics of Flapping Wings with Applications to Avian Fight [sic] written by Michael Shawn Vest and published by . This book was released on 1996 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Propulsive forces can be generated with flapping or heaving wings traveling through a fluid, as demonstrated in animal flight. The flow field of a bird in flight is one of the most complex aerodynamic problems that can be examined. Many other bird flight theories are based on quasi-steady fluid dynamic assumptions even though the flow field is inherently unsteady. To help examine the time dependency of bird flight, an unsteady three dimensional potential flow panel code was developed. Another problem in studying the aerodynamics of avian flight is the limited amount of quantitative experimental data on flapping wings. To gain further understanding of avian flight and to develop an experimental database for comparison of the fluid dynamic model, a mechanical bird was constructed and placed in a wind tunnel. The mechanical bird, modeled after a pigeon, is capable of flapping at various angles to the freestream flow. For the current study, however, the flapping motion was limited to a plane normal to the oncoming flow. Results of the numerical model were compared to the measured forces on the mechanical bird as well as to the limited data available on real birds. In one case, the model was applied to a flapping wing in a wind tunnel at high advance ratios $(J=4.31)$ where the computed average lift and thrust were within the error bounds of the experimental data. The model was also applied to high frequency flapping flight $(J=0.76)$ of a pigeon flying in a wind tunnel, where the predicted lift matched the weight of the bird. Time histories of the mechanical pigeon agreed well with the numerical predictions for high $(J=5.38)$ and low $(J=0.84)$ advance ratios. The model was also extended to examine the effect of wing twist on flight efficiencies. Flight characteristics of the mechanical bird and a real pigeon were also compared.

Download or read book Glimpses of Creatures in Their Physical Worlds written by Steven Vogel and published by Princeton University Press. This book was released on 2009-08-24 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Glimpses of Creatures in Their Physical Worlds offers an eye-opening look into how the characteristics of the physical world drive the designs of animals and plants. These characteristics impose limits but also create remarkable and subtle opportunities for the functional biology of organisms. In particular, Steven Vogel examines the size and scale, and trade-offs among different physical processes. He pays attention to how the forms and activities of animals and plants reflect the materials available to nature, and he explores the unique constraints and possibilities provided by fluid flow, structural design, and environmental forces. Each chapter of the book investigates a facet of the physical world, including the drag on small projectiles; the importance of diffusion and convection; the size-dependence of acceleration; the storage, conduction, and dissipation of heat; the relationship among pressure, flow, and choice in biological pumps; and how elongate structures tune their relative twistiness and bendiness. Vogel considers design-determining factors all too commonly ignored, and builds a bridge between the world described by physics books and the reality experienced by all creatures. Glimpses of Creatures in Their Physical Worlds contains a wealth of accessible information related to functional biology, and requires little more than a basic background in secondary-school science and mathematics. Drawing examples from creatures of land, air, and water, the book demonstrates the many uses of biological diversity and how physical forces impact biological organisms.

Available in PDF, EPUB and Kindle. Book excerpt: From Galileo, who used the hollow stalks of grass to demonstrate the idea that peripherally located construction materials provide most of the resistance to bending forces, to Leonardo da Vinci, whose illustrations of the parachute are alleged to be based on his study of the dandelion’s pappus and the maple tree’s samara, many of our greatest physicists, mathematicians, and engineers have learned much from studying plants. A symbiotic relationship between botany and the fields of physics, mathematics, engineering, and chemistry continues today, as is revealed in Plant Physics. The result of a long-term collaboration between plant evolutionary biologist Karl J. Niklas and physicist Hanns-Christof Spatz, Plant Physics presents a detailed account of the principles of classical physics, evolutionary theory, and plant biology in order to explain the complex interrelationships among plant form, function, environment, and evolutionary history. Covering a wide range of topics—from the development and evolution of the basic plant body and the ecology of aquatic unicellular plants to mathematical treatments of light attenuation through tree canopies and the movement of water through plants’ roots, stems, and leaves—Plant Physics is destined to inspire students and professionals alike to traverse disciplinary membranes.
