This book was released on 2012-08-31 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ultrasonic velocity profile (UVP) method, first developed in medical engineering, is now widely used in clinical settings. The fluid mechanical basis of UVP was established in investigations by the author and his colleagues with work demonstrating that UVP is a powerful new tool in experimental fluid mechanics. There are diverse examples, ranging from problems in fundamental fluid dynamics to applied problems in mechanical, chemical, nuclear, and environmental engineering. In all these problems, the methodological principle in fluid mechanics was converted from point measurements to spatio-temporal measurements along a line. This book is the first monograph on UVP that offers comprehensive information about the method, its principles, its practice, and applied examples, and which serves both current and new users. Current users can confirm that their application configurations are correct, which will help them to improve the configurations so as to make them more efficient and effective. New users will become familiar with the method, to design applications on a physically correct basis for performing measurements accurately. Additionally, the appendix provides necessary practical information, such as acoustic properties.

Download or read book Multiphase Flow Metering written by Gioia Falcone and published by Elsevier. This book was released on 2009-11-16 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last two decades the development, evaluation and use of MFM systems has been a major focus for the Oil & Gas industry worldwide. Since the early 1990's, when the first commercial meters started to appear, there have been around 2,000 field applications of MFM for field allocation, production optimisation and well testing. So far, many alternative metering systems have been developed, but none of them can be referred to as generally applicable or universally accurate. Both established and novel technologies suitable to measure the flow rates of gas, oil and water in a three-phase flow are reviewed and assessed within this book. Those technologies already implemented in the various commercial meters are evaluated in terms of operational and economical advantages or shortcomings from an operator point of view. The lessons learned about the practical reliability, accuracy and use of the available technology is discussed. The book suggests where the research to develop the next generation of MFM devices will be focused in order to meet the as yet unsolved problems. The book provides a critical and independent review of the current status and future trends of MFM, supported by the authors' strong background on multiphase flow and by practical examples. These are based on the authors' direct experience on MFM, gained over many years of research in connection with both operators and service companies. As there are currently no books on the subject of Multiphase Flow Metering for the Oil & Gas industry, this book will fill in the gap and provide a theoretical and practical reference for professionals, academics, and students.* Written by leading scholars and industry experts of international standing* Includes strong coverage of the theoretical background, yet also provides practical examples and current developments* Provides practical reference for professionals, students and academics

Download or read book Validating Color Doppler Ultrasound Performance Via a Quantitative Comparison with Particle Image Velocimetry written by Allan Alexander Andranikian and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Color Doppler Ultrasound (CDUS) is a method of non-invasive fluid velocity measurement that is used for regular cardiac screenings as well as during complex surgeries such as valve replacements. A Color Doppler image is a contour map of the velocity field and can thereby indicate the presence of abnormal flows or be used to quantitatively measure velocities. CDUS is inexpensive and completely non-invasive. It is for these same reasons that CDUS has the potential to be a powerful tool not only in the medical field, but in the industrial and engineering research fields as well. While there are many devices that use ultrasonic transducers to determine either pipe-wall corrosion or mean flow rate, to date making accurate velocity measurements has required either a clear visualization section or an invasive form of measurement. An experimental method to quantify the accuracy of Color Doppler Ultrasound velocity measurements in both the laminar and turbulent flow regime through a non-biological media is presented. A clear acrylic tube with a conical nozzle, throat, and a sudden expansion is used to generate a well characterized flow field that includes features typical of physiologic flows and flows within medical devices such as high speed jets and recirculation. The velocity field is measured at three locations using both Color Doppler Ultrasound and Particle Image Velocimetry (PIV) and the measurements are used to generate velocity profiles, which are compared quantitatively. It was found that although it is possible to resolve phenomena such as recirculation and high speed jets, the media through which the imaging occurs has a significant impact on the accuracy of the Ultrasound generated velocity measurements. Due to the large amount of attenuation of sound through acrylic media, the Color Doppler readings show significant error in velocity measurements. For laminar parabolic flows this shifts both the mean and peak velocities down, with a percent difference in both as high as 42% and 55% respectively. However, at the sudden expansion where high speed jets and recirculation zones occur, the velocity profile becomes wider and flatter, and though the peak velocity measurements have a percent difference of approximately 50%, the percent difference in the mean velocity varied from less than 1% to a maximum of 10%."--Abstract.

Download or read book Method and Apparatus for Ultrasonic Doppler Velocimetry Using Speed of Sound and Reflection Mode Pulsed Wideband Doppler written by and published by . This book was released on 2000 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: According to the present invention, a method and apparatus rely upon tomographic measurement of the speed of sound and fluid velocity in a pipe. The invention provides a more accurate profile of velocity within flow fields where the speed of sound varies within the cross-section of the pipe. This profile is obtained by reconstruction of the velocity profile from the local speed of sound measurement simultaneously with the flow velocity. The method of the present invention is real-time tomographic ultrasonic Doppler velocimetry utilizing a to plurality of ultrasonic transmission and reflection measurements along two orthogonal sets of parallel acoustic lines-of-sight. The fluid velocity profile and the acoustic velocity profile are determined by iteration between determining a fluid velocity profile and measuring local acoustic velocity until convergence is reached.
