This book was released on 2009-12-01 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is devoted to investigation of a series of problems of convective heat and mass transfer in rotating-disk systems. Such systems are widespread in scienti?c and engineering applications. As examples from the practical area, one can mention gas turbine and computer engineering, disk brakes of automobiles, rotating-disk air cleaners, systems of microclimate, extractors, dispensers of liquids, evaporators, c- cular saws, medical equipment, food process engineering, etc. Among the scienti?c applications, it is necessary to point out rotating-disk electrodes used for experim- tal determination of the diffusion coef?cient in electrolytes. The system consisting of a ?xed disk and a rotating cone that touches the disk by its vertex is widely used for measurement of the viscosity coef?cient of liquids. For time being, large volume of experimental and computational data on par- eters of ?uid ?ow, heat and mass transfer in different types of rotating-disk systems have been accumulated, and different theoretical approaches to their simulation have been developed. This obviously causes a need of systematization and generalization of these data in a book form.

This book was released on 2015-07-15 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Brief describes systematically results of research studies on a series of convective heat transfer phenomena from rotating disks in air crossflow. Phenomena described in this volume were investigated experimentally using an electrically heated disk placed in the test section of a wind tunnel. The authors describe findings in which transitions between different heat transfer regimes can occur in dependency on the involved Reynolds numbers and the angle of incidence, and that these transitions could be related to phenomenological Landau and Landau-de Gennes models. The concise volume closes a substantial gap in the scientific literature with respect to flow and heat transfer in rotating disk systems and provides a comprehensive presentation of new and recent results not previously published in book form.

This book was released on 2015-07-24 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph presents results of the analytical and numerical modeling of convective heat and mass transfer in different rotating flows caused by (i) system rotation, (ii) swirl flows due to swirl generators, and (iii) surface curvature in turns and bends. Volume forces (i.e. centrifugal and Coriolis forces), which influence the flow pattern, emerge in all of these rotating flows. The main part of this work deals with rotating flows caused by system rotation, which includes several rotating-disk configurations and straight pipes rotating about a parallel axis. Swirl flows are studied in some of the configurations mentioned above. Curvilinear flows are investigated in different geometries of two-pass ribbed and smooth channels with 180° bends. The author demonstrates that the complex phenomena of fluid flow and convective heat transfer in rotating flows can be successfully simulated using not only the universal CFD methodology, but in certain cases by means of the integral methods, self-similar and analytical solutions. The book will be a valuable read for research experts and practitioners in the field of heat and mass transfer.

Available in PDF, EPUB and Kindle. Book excerpt: This volume is devoted to the flow and heat transfer between co-rotating discs, and unifies the subject by means of physical insight and mathematical models, validated using experimental data. Many phenomena, unique to rotating flows, are explained, and empirical correlations and theoretical methods, suitable for design purposes, are presented. Data is provided within the book for validating CFD codes which are being increasingly used to compute the flow in rotating-disc systems. Since the publication of Volume 1 in 1989, there has been an increasing interest in rotating disc systems, mainly from research workers and engine designers concerned with understanding and computing the complex flow and heat transfer that occur inside the internal cooling-systems of gas-turbine engines. This book should be of interest to them as it may assist them in making more efficient use of cooling air systems, resulting in both economic and environmental benefits.

This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Flow and heat transfer of NH[sub 3] and He were studied in a rotating disk system with applications to chemical vapor deposition reactors. Flow field and disk heat flux were obtained over a range of operating conditions. Comparisons of disk convective heat transfer were made to infinite rotating disk results to appraise uniformity of transport to the disk. Important operating variables include disk spin rate, disk and enclosure temperatures, flow rate, composition, pressure, and gas mixture temperature at the reactor inlet. These variables were studied over ranges of the spin Reynolds number, Re[omega]; disk mixed convection parameter, MCP[sub w]; and wall mixed convection parameter, MCP[sub w]. Results obtained for NH[sub 3] show that increasing Re[omega] from 314.5 to 3145 increases the uniformity of rotating disk heat flux and results in thinner thermal boundary layers at the disk surface. At Re[omega]=314.5, increasing MCP[sub d] to 15 leads to significant departure from the infinite disk result with nonuniform disk heat fluxes and recirculating flow patterns; flow becomes increasingly complex at larger values of MCP[sub d]. At Re[omega] of 3145, results are closer to the infinite disk for MCP[sub d] up to 15. For large negative (hot walls) and positive (cold walls) values of MCP[sub w], flow recirculates and there is significant deviation from the infinite disk result; nonuniformities occur at both values of Re[omega]. The influence of MCP[sub w] on flow stability is increased at larger MCP[sub d] and lower Re[omega]. To determine the influence of viscosity and thermal conductivity variation with temperature, calculations were made with He and NH[sub 3]; He transport property variation is low relative to NH[sub 3]. Results show that the flow of NH[sub 3] is less stable than that of He as MCP[sub d] is increased for MCP[sub w]=0 and Re[omega]=314.5. 16 refs., 15 figs., 1 tab.

Available in PDF, EPUB and Kindle. Book excerpt: The flow and heat transfer of NH3 and He have been studied in a rotating disk system with applications to chemical vapor deposition reactors. Influence of the important operating parameters were studied numerically over ranges of the primary dimensionless variables: (1) the spin Reynolds number, Re{sub {omega}}, (2) the disk mixed convection parameter, MCP{sub d}, and (3) a new parameter, the wall mixed convection parameter, MCP{sub w}. Inlet velocities were set to the corresponding infinite rotating disk asymptotic velocity. Results were obtained primarily for NH3. Results show that increasing Re{sub {omega}} from 314.5 to 3,145 increases the uniformity of the rotating disk heat flux and results in thinner thermal boundary layers at the disk surface. At Re{sub {omega}} = 314.5, increasing MCP{sub d} to 15 leads to significant departure from the infinite disk result with nonuniform disk heat fluxes and recirculating flow patterns. At Re{sub {omega}} = 3,145, the results are closer to the infinite disk for MCP{sub d} up to 15. For large values of MCP{sub w}, the flow recirculates and there is significant deviation from the infinite disk result. The influence of MCP{sub w} on flow stability is increased at larger MCP{sub d} and lower Re{sub {omega}}. The results show that because of variable transport properties, the flow of NH3 is less stable than that of He as MCP{sub d} is increased for MCP{sub w} = 0 and Re{sub {omega}} = 314.5.
