Providing ample detail for self study and the sort of elegant writing rarely found in so thorough a treatment, he provides insight into all the vital topics and issues associated with the devices and instruments used for fluid mechanics and gas dynamics experiments. Extremely organized, this work presents easy access to the principles behind the science and goes on to elucidate the current research and findings needed by those seeking to make further advancement.
Unique and Thorough Coverage of Uncertainty Analysis The author provides valuable insight into the vital issues associated with the devices used in fluid mechanics and gas dynamics experiments. Leaving nothing to doubt, he tackles the most difficult concepts and ends the book with an introduction to uncertainty analysis.
Structured and detailed enough for self study, this volume also provides the backbone for both undergraduate and graduate courses on fluids experimentation. Coverage is also given to the instrumental requirements for these applications, with respect to the high pressure instrumentation and the spectroscopic components of the equipment. The pedagogical style of the book is supplemented by the inclusion of "study questions" which aim to make it useful for graduate-level courses. It offers breadth and inclusiveness.
Most existing works on automotive painting cover only a single aspect of this complex topic, such as the chemistry of paint or paint booth technology. The Monozukuri-Hitozukuri perspective is drawn from essential principles on which the Toyota approach to problem-solving and continuous improvement is based. The editors provide case studies and examples -- drawn from Mr.
This hands-on book thoroughly discusses the nature of turbulence effects on optical imaging systems, techniques used to overcome these effects, performance analysis methods, and representative examples of performance. Neatly pulling together widely scattered material, it covers Fourier and statistical optics, turbulence effects on imaging systems, simulation of turbulence effects and correction techniques, speckle imaging, adaptive optics, and hybrid imaging.
Imaging Through Turbulence is written in tutorial style, logically guiding you through these essential topics. It helps you bring down to earth the complexities of coping with turbulence. His assignment was to work at the supersonic wind tunnels of the rocket laboratories of the German Army. Here Wernher von Braun led a team that developed the V-2, the world's first large rocket-powered guided missile, and laid much of the groundwork for postwar rocket development.
He tells how he was working one night in August when the Allies bombed the laboratories, but left the wind tunnels undamaged. The tunnels were moved to Bavaria, and Wegener was ordered to follow in After the war, the tunnels were moved again--this time to the United States, accompanied by the author and other German scientists. Shortly before the end of the war, Wegener visited Germany's underground V-2 production plant to retrieve archival material on aerodynamics that had been stored in caves for safekeeping.
He describes the appalling history of the concentration camps where SS guards watched over inmates who toiled underground in inhuman conditions and often did not survive.
