Book Synopsis Aerosol Measurement by : Paul A. Baron
Download or read book Aerosol Measurement written by Paul A. Baron and published by Wiley-Interscience. This book was released on 2001-10 with total page 1170 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, industry has become increasingly interested in modern aerosol measurement methods, not only to protect the health of their workers but also to augment productivity and thereby gain competitive advantage. Aerosol Measurement: Principles, Techniques, and Applications, Second Edition offers scientists and practitioners the fundamental principles used in deciding which aerosol properties to measure and how to interpret the results. Divided into three parts, the material reviews the physical understanding of aerosols, covers specific instrumental techniques, and explains applications in fields ranging from health care to mining and upper-atmosphere research. Leading experts contribute to the review of such areas as direct-reading techniques, bioaerosol sampling, indoor air evaluations, industrial aerosol processing, and measurement in semiconductor clean rooms. Plus, all the chapters in this latest edition have been updated and some have been rewritten by new authors. Two new chapters have been added: one on historical aspects of aerosol measurements and the other on real-time single particle analysis.

Book Synopsis A Study of Turbulent Flow in Rough Pipes by : James Mueller Robertson
Download or read book A Study of Turbulent Flow in Rough Pipes written by James Mueller Robertson and published by . This book was released on 1965 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The considerable literature on turbulent flow past rough surfaces is correlated in terms of modes of presenting the smooth-to-rough transition and the influences of roughness density and shape. Flow measurements in a 3 in. smooth and sand roughened pipe and in an 8 in. steel pipe with 'natural' roughness are reported. The temporal-mean velocity and friction measurements show transitional (between smooth and fully rough behavior) variations. The pipe factor variation is also elucidated; the sand-roughened pipe studies indicate a shift in Nikuradse's presentation. The turbulence - as intensity divided by shear velocity and macroscale in ratio to pipe radius - in rough pipe flow appears the same in rough as in smooth pipe flow. The relative turbulence intensity is constant, or at most decreases slowly with increase in flow Reynolds number. (Author).
Book Synopsis Velocity Measurements in a High-speed Flow Through a Square Duct Containing a 90° Bend by : Preyank Sheth
Download or read book Velocity Measurements in a High-speed Flow Through a Square Duct Containing a 90° Bend written by Preyank Sheth and published by . This book was released on 2009 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study is aimed at better understanding the nature of bend effects in a high Reynolds number duct flow. Bend effects have been previously studied using laser Doppler velocimetry and hot wire anemometry, but these are point measurement techniques, which limits the amount and type of data that can be obtained. The current work employs particle image velocimetry to present detailed field measurements of the flow velocity throughout the bend, including upstream and downstream sections. Additionally, velocity measurements have been carried out at three different Reynolds numbers to establish the dependence or independence of the bend effects on the flowrate. Associated turbulence quantities have also been calculated and presented in an intuitive, graphical manner. The test section is a square cross-sectioned duct, containing a 90 degree bend preceded by an 5Dh[subscript] upstream section and a 10Dh[subscript] downstream straight section, where Dh[subscript] is the hydraulic diameter. Turbulent flow entering the upstream section is fully-developed to allow the isolation of the bend effects. At Re ~ 2.76X105, detailed velocity measurements are acquired at 12 streamwise locations in three streamwise-radial planes at different heights (top, middle and bottom). Complementary data are obtained in a more limited set of locations at Re~1.76X105 and Re~3.20X105 to allow comparison of the bend effects at different flowrates. Turbulence intensities and the Reynolds shear stress components are calculated and presented for all three Reynolds numbers. One of the major aims of this work is to provide a benchmark for computational codes developed to study bend effects in a turbulent pipe flow. To allow easy comparison of these codes to the results of the current study, all the measured and calculated quantities are plotted in a curvilinear coordinate system in addition to the native cartesian (global) coordinate system.

Book Synopsis Laws of Flow in Rough Pipes by : J. Nikuradse
Download or read book Laws of Flow in Rough Pipes written by J. Nikuradse and published by . This book was released on 1950 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation is made of the turbulent flow of water in pipes with various degrees of relative roughness. The pipes range in size from 25 to 100 millimeters in diameter and from 1800 to 7050 millimeters in length. Flow velocities permitted Reynolds numbers from about 10 (sup. 4) to 10 (sup. 6). The laws of resistance and velocity distributions were obtained as a function of relative roughness and Reynolds number. Mixing length, as described by Prandtl's mixing-length formula, is discussed in relation to the experimental results.

Book Synopsis Evaluation of High Reynolds Number Flow in a 180 Degree Turn-Around-Duct by : National Aeronautics and Space Administration (NASA)
Download or read book Evaluation of High Reynolds Number Flow in a 180 Degree Turn-Around-Duct written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-07-02 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mean and turbulent velocities were measured for the flow in a 180 degree turn-around-duct over a Reynolds number range from 600,000 to greater than 900,000. The measurements were made in water using a forward scattering laser velocimeter. A duct of 100 x 10 cm constant cross-section, with a mean radius of curvature (centerline) of 10 cm was employed for the study. The measurements are in agreement with previous studies in that the use of local bulk velocity to nondimensionalize the mean and turbulent velocities reduce the Reynolds number variations. The basic phenomenon of relaminarization along the inner surface at the exit of the turn are similar to the flow observed at low Reynolds numbers. The separation bubble region shows a systematic variation with Reynolds number, however the Reynolds number effect may be of second order in the calculation of the overall flow. Large tangential, radial, and lateral turbulent velocities are measured along the outer surface of the turn. Sandborn, V. A. and Marcy, S. J. Unspecified Center NAS8-38186...
Book Synopsis Measurements with Particle Image Velocimetry on Fully Developed Turbulent Pipe Flow at Low Reynolds Number by : J. Westerweel
Download or read book Measurements with Particle Image Velocimetry on Fully Developed Turbulent Pipe Flow at Low Reynolds Number written by J. Westerweel and published by . This book was released on 1992 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measurements with particle image velocimetry were carried out in fully developed turbulent pipe flow at a Reynolds number of 5,277. Data were obtained in a plane through the centerline of the pipe, across the full diameter. Statistical properties of the flow obtained by ensemble averaging of the data along the axial direction were in good agreement with direct numerical simulation. Maps of instantaneous tangential vorticity reveal spatial structures near the pipe wall that resemble coherent flow structures predicted by direct numerical simulation. (Author).
