Download or read book PC Aided Numerical Heat Transfer and Convective Flow written by Akira Nakayama and published by CRC Press. This book was released on 1995-04-07 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: PC-Aided Numerical Heat Transfer and Convective Flow is intended as a graduate course textbook for Mechanical and Chemical Engineering students as well as a reference book for practitioners interested in analytical and numerical treatments in the subject. The book is written so that the reader can use the enclosed diskette, with the aid of a personal computer, to systematically learn both analytical and numerical approaches associated with fluid flow and heat transfer without resorting to complex mathematical treatments. This is the first book that not only describes solution methodologies but also provides complete programs ranging from SOLODE to SAINTS for integration of Navier-Stokes equation. The book covers boundary layer flows to fully elliptic flows, laminar flows to turbulent flows, and free convection to forced convection. The student will learn about convection in porous media, a new field of rapid growth in contemporary heat transfer research. A basic knowledge of fluid mechanics and heat transfer is assumed. It is also assumed that the student knows the basics of Fortran and has access to a personal computer.The material can be presented in a one-semester course or with selective coverage in a seminar.

This book was released on 1979 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thick, fully rough, and transitionally rough turbulent boundary layers were studied in order to investigate the differences between fully rough and transitionally rough behavior and to observe how downstream development affects these flows as the boundary layers become very thick. Measurements included Stanton numbers, skin friction coefficients, mean temperature and velocity profiles, Reynolds stress tensor component profiles, and spectra of the longitudinal velocity fluctuations. Predictions of wall heat transfer, wall shear, and mean profiles were made using a mixing-length and turbulent Prandtl number closure scheme which accounted for the effects of wall roughness in the boundary layer equations. The turbulent layers were artificially thickened using an array of solid obstacles which produced a two-dimensional equilibrium flow field with properties representative of natural bounday layers, at least up to the level of the turbulent correlations on a smooth wall, and to the level of the spectra of longitudinal velocity fluctuations on a rough wall. A rough-wall boundary layer environment was provided in which all measurements of lower order than the turbulence correlations could be discussed regarding the influence of roughness, and considered to have properties representative of natural behavior.

Available in PDF, EPUB and Kindle. Book excerpt: Spacecraft, space platform, and manned and unmanned space exploration of the future will require increasingly large sources of power for which a variety of conventional and novel systems are being designed. These systems will require heat exchangers as key components, as well as for waste heat rejection. Electronics will be utilized which will also require heat exchangers for cooling. To meet these future waste heat rejection requirements, it is of paramount importance to encourage researchers and practitioners to develop innovative heat exchanger concepts for aerospace applications. The 46 papers in this volume disseminate state-of-the-art information on current developments in this field. The choice of topics reflect the variety and diversity of recent progress in aerospace heat exchanger technology.

Available in PDF, EPUB and Kindle. Book excerpt: An analysis of combined heat and mass transfer from a flat plate has been made in terms of Prandtl's simpified physical concept of the turbulent boundary layer. The results of the analysis show that tor conditioins of reasonably small heat and mass transfer, the ratio of the mass- and heat-transfer coefficients is dependent on the Reynolds number of the boundary layer, the Prandtl number of the medium of diffusion, and the Schmidt number of the diffusing fluid in the medium of diffusion. For the particular case of water evaporating into air, the ratio of mass-transfer coefficient to heat-transfer coefficient is found to be slightly greater than unity.

Available in PDF, EPUB and Kindle. Book excerpt: Progress in Heat and Mass Transfer, Volume 5: Heat and Mass Transfer in Rheologically Complex Fluids compiles selected papers presented at the International Seminar held in Herceg Novi, Yugoslavia on September 8-12, 1970. This book discusses the continuum foundation of rheology; transport phenomena in turbulent flow of rheologically complex fluids; and heat-transfer effects in flowing polymers. The thixotropic effects in viscoelastic media; non-equilibrium thermodynamics and rheology of viscoelastic fluids; and flow instability due to convective time changes of consistency are also elaborated. This publication also covers the prediction method for turbulent momentum and heat transfer in viscous non-Newtonian liquids; methods for determining thermal properties of anisotropic systems; and convection in ferromagnetic fluid due to magneto caloric effect. This volume is beneficial to students and researchers interested in the heat and mass transfer in rheologically complex fluids.

This book was released on 2013-04-18 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is concerned with the transport of thermal energy in flows of practical significance. The temperature distributions which result from convective heat transfer, in contrast to those associated with radiation heat transfer and conduction in solids, are related to velocity characteristics and we have included sufficient information of momentum transfer to make the book self-contained. This is readily achieved because of the close relation ship between the equations which represent conservation of momentum and energy: it is very desirable since convective heat transfer involves flows with large temperature differences, where the equations are coupled through an equation of state, as well as flows with small temperature differences where the energy equation is dependent on the momentum equation but the momentum equation is assumed independent of the energy equation. The equations which represent the conservation of scalar properties, including thermal energy, species concentration and particle number density can be identical in form and solutions obtained in terms of one dependent variable can represent those of another. Thus, although the discussion and arguments of this book are expressed in terms of heat transfer, they are relevant to problems of mass and particle transport. Care is required, however, in making use of these analogies since, for example, identical boundary conditions are not usually achieved in practice and mass transfer can involve more than one dependent variable.
