Available in PDF, EPUB and Kindle. Book excerpt: Calculations of steady laminar incompressible fluid-flow and heat transfer in a spherical annulus are presented. Steady pressures, temperatures, velocities, and heat transfer coefficients are calculated for an insulated outer sphere and a 0°C isothermal inner sphere with 50°C heated water flowing in the annulus. The inner sphere radius is 13.97 cm, the outer sphere radius is 16.83 cm and the radius ratio is 1.2. The transient axisymmetric equations of heat, mass, and momentum conservation are solved numerically in spherical coordinates. The transient solution is carried out in time until steady state is achieved. A variable mesh is used to improve resolution near the inner sphere where temperature and velocity gradients are steep. It is believed that this is the first fully two-dimensional analysis of forced flow in a spherical annulus. Local and bulk Nusselt numbers are presented for Reynolds numbers from 4.4 to 440. Computed bulk Nusselt numbers ranged from 2 to 50 and are compared to experimental results from the literature. Inlet flow jetting off the inner sphere and flow separation are predicted by the analysis. The location of wall jet separation was found to be a function of Reynolds number, indicating the location of separation depends upon the ratio of inertia to viscous forces. Wall jet separation has a pronounced effect on the distribution of local heat flux. The area between inlet and separation was found to be the most significant area for heat transfer. Radial distributions of azimuthal velocity and temperature are presented for various angles beginning at the inlet. Inner sphere pressure distribution is presented and the effect on flow separation is discussed.

Download or read book Free Convective Heat Transfer written by Oleg G. Martynenko and published by Springer Science & Business Media. This book was released on 2005-12-06 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: Free Convective Heat Transfer is a thorough survey of various kinds of free-convective flows and heat transfer. Reference data are accompanied by a large number of photographs originating from different optical visualization methods illustrating the different types of flow. The formulas derived from numerical and analytical investigations are valuable tools for engineering calculations. They are written in their most compact and general form in order to allow for an extensive range of different variants of boundary and initial conditions, which, in turn, leads to a wide applicability to different flow types. Some specific engineering problems are solved in the book as exemplary applications of these formulas.

Download or read book Studies on Heat Transfer in Laminar Free Convection with the Zehnder Mach Interferometer written by Ernst Rudolf Georg Eckert and published by . This book was released on 1948 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heat transfer in thermal free convection of air was investigated with the aid of a Zehnder-Mach interferometer on bodies with different shapes such as vertical plates; horizontal cylinders with circular and square cross-sections; arrangements of two and three horizontal cylinders; and an air-space enclosed between two horizontal concentric cylinders. All forms had in common that the convection flow set-up was two-dimensional. Free convection heat transfer has immediate application-possibilities for modern aircraft power plants for cooling and insulating problems connected with the handling of jet-engine fuels and rocket propellants. In the course of the studies, it was found that valuable information can be gained, by the interferometer method used, on turbulence. Data on thermal convection are useful also in understanding radial flow phenomena, which are caused by centrifugal forces in turbo-compressors and turbines. Data on heat transfer in turbulent-free convection will be presented at a later data.

Book excerpt: Interest in studying the phenomena of convective heat and mass transfer between an ambient fluid and a body which is immersed in it stems both from fundamental considerations, such as the development of better insights into the nature of the underlying physical processes which take place, and from practical considerations, such as the fact that these idealised configurations serve as a launching pad for modelling the analogous transfer processes in more realistic physical systems. Such idealised geometries also provide a test ground for checking the validity of theoretical analyses. Consequently, an immense research effort has been expended in exploring and understanding the convective heat and mass transfer processes between a fluid and submerged objects of various shapes. Among several geometries which have received considerable attention are plates, circular and elliptical cylinders, and spheres, although much information is also available for some other bodies, such as corrugated surfaces or bodies of relatively complicated shapes. The book is a unified progress report which captures the spirit of the work in progress in boundary-layer heat transfer research and also identifies potential difficulties and areas for further study. In addition, this work provides new material on convective heat and mass transfer, as well as a fresh look at basic methods in heat transfer. Extensive references are included in order to stimulate further studies of the problems considered. A state-of-the-art picture of boundary-layer heat transfer today is presented by listing and commenting also upon the most recent successful efforts and identifying the needs for further research.
