Available in PDF, EPUB and Kindle. Book excerpt: Experiments showed that fully developed heattransfer results, predicted by a previous analysis, were confirmed over the range of Rayleigh numbers investigated. The concept of locally fully developed heat transfer was established. Thermal entrance region data were obtained for pure forced convection and for combined forcedAND FREE CONVECTION. The analysis of laminar pure forced convection in the thermal entrance region conducted by Siegel, Sparrow, and Hallman (Appl. Sci. Res., Sec. A, Vol. 7, No. 5, 386-392, 1958) was experimentally confirmed. A tansition to an eddy motion, indicaed by a fluctuation in wall temperature, was found in many of the upflow runs. A stability correlation was found. The fully developed Nusselt numbers in downflow were below those for pure forced convection but fell about 10 percent above the analytical curve. Quite large circumferential variations in wall temperature were observed in downflow as compared with those encountered in upflow. With larger heating rates in downflow the wall temperature distributions strongly suggested a cell flow near the bottom. At still larger heating rates the wall temperatures varied in a periodic way.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Explore the Radiative Exchange between Surfaces Further expanding on the changes made to the fifth edition, Thermal Radiation Heat Transfer, 6th Edition continues to highlight the relevance of thermal radiative transfer and focus on concepts that develop the radiative transfer equation (RTE). The book explains the fundamentals of radiative transfer, introduces the energy and radiative transfer equations, covers a variety of approaches used to gauge radiative heat exchange between different surfaces and structures, and provides solution techniques for solving the RTE. What’s New in the Sixth Edition This revised version updates information on properties of surfaces and of absorbing/emitting/scattering materials, radiative transfer among surfaces, and radiative transfer in participating media. It also enhances the chapter on near-field effects, addresses new applications that include enhanced solar cell performance and self-regulating surfaces for thermal control, and updates references. Comprised of 17 chapters, this text: Discusses the fundamental RTE and its simplified forms for different medium properties Presents an intuitive relationship between the RTE formulations and the configuration factor analyses Explores the historical development and the radiative behavior of a blackbody Defines the radiative properties of solid opaque surfaces Provides a detailed analysis and solution procedure for radiation exchange analysis Contains methods for determining the radiative flux divergence (the radiative source term in the energy equation) Thermal Radiation Heat Transfer, 6th Edition explores methods for solving the RTE to determine the local spectral intensity, radiative flux, and flux gradient. This book enables you to assess and calculate the exchange of energy between objects that determine radiative transfer at different energy levels.

Download or read book Convective Heat Transfer Second Edition written by Sadik Kakaç and published by CRC Press. This book was released on 1994-12-16 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: Convective Heat Transfer presents an effective approach to teaching convective heat transfer. The authors systematically develop the topics and present them from basic principles. They emphasize physical insight, problem-solving, and the derivation of basic equations. To help students master the subject matter, they discuss the implementations of the basic equations and the workings of examples in detail. The material also includes carefully prepared problems at the end of each chapter. In this Second Edition, topics have been carefully chosen and the entire book has been reorganized for the best presentation of the subject matter. New property tables are included, and the authors dedicate an entire chapter to empirical correlations for a wide range of applications of single-phase convection. The book is excellent for helping students quickly develop a solid understanding of convective heat transfer.
