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.

Download or read book Laminar Flow Forced Convection in Ducts written by R. K. Shah and published by Academic Press. This book was released on 2014-06-28 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: Laminar Flow Forced Convection in Ducts is a sourcebook for compact heat exchanger analytical data. This book describes the analytical solutions for laminar fluid flow and forced convection heat transfer in circular and noncircular pipes, including applicable differential equations and boundary conditions involving velocity and temperature problems of fluid flow. The book also discusses fluid flow—how much power is required to pump fluids through the heat exchanger, as well as the heat transfer—the determination of q" distribution, and the temperature of fluid and walls. The text also analyzes the coolant or heat transfer fluid flows in a nuclear power reactor composed of a bundle of circular section fuel rods located inside a round tube. R.A. Axford addresses fluid flow and heat transfers results for the rod bundle geometry in "Heat Transfer in Rod Bundles." The book also provides an overview and guidelines that can be used for the designer and the applied mathematician. This book is suitable for engineers working in electronics, aerospace, instrumentation, and biomechanics that use cooling or heating exchanges or solar collection systems.
