Available in PDF, EPUB and Kindle. Book excerpt: Test results are presented for the thermal conductivity, over a broad range of temperatures and pressures, of two refractory blown fiber insulations. The data, which were obtained for several bulk densities of each material, are compared with predictions from a theoretical expression that accounts for radiation transmission as well as solid and gas conduction contributions to the effective conductivity. The simple model utilized provides a remarkably accurate prediction of insulation performance for the materials of interest and, therefore, represents a useful tool for design purposes, minimizing the amount of actual testing necessary to characterize candidate materials. Criteria are indicated by which it is possible to determine whether the model will be applicable to a given fiber insulation. This study was accomplished over a two and one-half year period, in support of the Space Shuttle thermal protection system design.

Download or read book Fluid Mechanics Heat Transfer and Mass Transfer written by K. S. Raju and published by John Wiley & Sons. This book was released on 2011-04-20 with total page 1422 pages. Available in PDF, EPUB and Kindle. Book excerpt: This broad-based book covers the three major areas of Chemical Engineering. Most of the books in the market involve one of the individual areas, namely, Fluid Mechanics, Heat Transfer or Mass Transfer, rather than all the three. This book presents this material in a single source. This avoids the user having to refer to a number of books to obtain information. Most published books covering all the three areas in a single source emphasize theory rather than practical issues. This book is written with emphasis on practice with brief theoretical concepts in the form of questions and answers, not adopting stereo-typed question-answer approach practiced in certain books in the market, bridging the two areas of theory and practice with respect to the core areas of chemical engineering. Most parts of the book are easily understandable by those who are not experts in the field. Fluid Mechanics chapters include basics on non-Newtonian systems which, for instance find importance in polymer and food processing, flow through piping, flow measurement, pumps, mixing technology and fluidization and two phase flow. For example it covers types of pumps and valves, membranes and areas of their use, different equipment commonly used in chemical industry and their merits and drawbacks. Heat Transfer chapters cover the basics involved in conduction, convection and radiation, with emphasis on insulation, heat exchangers, evaporators, condensers, reboilers and fired heaters. Design methods, performance, operational issues and maintenance problems are highlighted. Topics such as heat pipes, heat pumps, heat tracing, steam traps, refrigeration, cooling of electronic devices, NOx control find place in the book. Mass transfer chapters cover basics such as diffusion, theories, analogies, mass transfer coefficients and mass transfer with chemical reaction, equipment such as tray and packed columns, column internals including structural packings, design, operational and installation issues, drums and separators are discussed in good detail. Absorption, distillation, extraction and leaching with applications and design methods, including emerging practices involving Divided Wall and Petluk column arrangements, multicomponent separations, supercritical solvent extraction find place in the book.

Download or read book Investigation of the Thermal Properties of High temperature Insulation Materials written by A. E. Wechsler and published by . This book was released on 1963 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: This program encompasses an analytical and experimental investigation of the thermal properties of high temperature insulation materials. Effective thermal conductivities of graphite and zirconia fibers were measured in the temperature range of -320 to 200 F. The results were compared with empirical and theoretical models of heat transfer in fibrous insulations. Measurements of visible and infrared transmission through insulation materials indicated that scattering is the principal mechanism of radiation attenuation. Scattering and absorption cross sections estimated from the transmission data are given and show little effect of insulation temperature. The effective thermal conductivities of evacuated insulation systems were measured in the temperature range from 60 to 4000 F. The stability of materials exposed to high temperature vacuum environment for up to 170 hours was studied.
Download or read book Estimated Viscosities and Thermal Conductivities of Gases at High Temperatures written by Roger A. Svehla and published by . This book was released on 1963 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Viscosities and thermal conductivities, suitable for heat-transfer calculations, were estimated for about 200 gases in the ground state from 100° to 5000° K and 1-atm pressure. Free radicals were included, but excited states and ions were not. Calculations for the transport coefficients were based upon the Lennard-Jones (12-6) potential for all gases. Intermolecular force constants for this potential were obtained from experimental viscosity data or were estimated when data were not available. The same set of constants was used to calculate both viscosity and conductivity. An Eucken-type correction for exchange between internal and translational energies was made for thermal conductivities of polyatomic gases.
