This book was released on 1989 with total page 670 pages. Available in PDF, EPUB and Kindle. Book excerpt: A direct numerical simulation of a fully developed turbulent channel flow with passive heat transfer is performed. The time-dependent three-dimensional Navier-Stokes equations and advection-diffusion equation are solved numerically using a pseudospectral technique with 1,064,960 grid points in physical space (128 x 65 x 128 in x, y, z). No subgrid scale model is employed since all essential turbulence scales are resolved. The Reynolds number is 2262, based on the half channel height and bulk velocity, and the Prandtl number is 1. The Nusselt number is predicted to be 25.36. A large number of one-point turbulence statistics are computed and compared with existing experimental data taken at similar Reynolds and Nusselt numbers. Agreement with the existing experimental data is excellent except for some discrepancies in the near wall region, y$sp+$ $

Book excerpt: Numerical Prediction of Flow, Heat Transfer, Turbulence and Combustion: Selected Works of Professor D. Brian Spalding focuses on the many contributions of Professor Spalding on thermodynamics. This compilation of his works is done to honor the professor on the occasion of his 60th birthday. Relatively, the works contained in this book are selected to highlight the genius of Professor Spalding in this field of interest. The book presents various research on combustion, heat transfer, turbulence, and flows. His thinking on separated flows paved the way for the multi-dimensional modeling of turbulence. Arguments on the universality of the models of turbulence and the problems that are associated with combustion engineering are clarified. The text notes the importance of combustion science as well as the problems associated with it. Mathematical computations are also presented in determining turbulent flows in different environments, including on curved pipes, curved ducts, and rotating ducts. These calculations are presented to further strengthen the claims of Professor Spalding in this discipline. The book is a great find for those who are interested in studying thermodynamics.

This book was released on 1992 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study, a directional-implicit Computational Fluid Dynamics (CFD)finite difference code is developed so as to simulate the direct and indirect heat removal through conduction and convection processes from the rectangular blocks attached to the lower surface of a narrow- channel geometry. Two dimensional, unsteady, incompressible, laminar form of the Navier -Stokes (N-S) equations are considered. L sing the stream function-vorticity approach, they are discretized via finite difference technique, under the assumption of the Taylor series expansions. The discretized equations than reduced to a three-banded form of a matrix equality ready to be used conjugate solution formulation. In the same manner, two dimensional unsteady' energy· equation discretized with the source term included into three-banded matrix form. Tw-o field equations are solved numerically for various channel-rectangular block geometries so as to study the steady--state heat transfer characteristics inside channel with possible heat generation inside the blocks. It is shown that the numerical model is capable of simulating the main features of the flow- field. Detailed benchmarks of the present numerical model is attempted so as to validate the devoloped algorithm. The streamvise extension of the recirculation zone behind the rectangular block which is a function of the Reynolds number is very well simulated. Furthermore, it was shown that the heat transfer characteritics of the zone agrees well with the experinıental and theoretical observations in the literature. Prepared algorithm is a highly' stable algorithm but show'ing slow convergence to a steady state value. Conjugate solution property of the present approach enables one to study complex thermal characteristics of fluid-solid and solid-solid interactions. Beside the classical boundary conditions of the thermal field, the problem domain is further complicated by the presence of discrete heat sources in the rectangular blocks in form of the infinite small heat generating sheet. Heat generatedat various transfer positions are convected by the fluid downstream. The near wall flow temperature and the Nusselt number distributions over the surface depict the most features of the complex fluid-solid interaction. The steady state temperature inside the blocks and in the substrate are found to be functions of the flow Reynolds number. Prandtl number, heat source position and substrate bottom surface temperature. Due to the heat generation the flow is heated well above its inlet value. This causes continous heat flow from fluid to the lower plate in the recirculating regions of the rectangular blocks and in the cavities where there are more than one obstacle. The present model can simulate the chip cooling problems for integrated circuit components, i.e, chips, on a horizontal printed curcuit board which is containing heat generatin; rectangular blocks attached to a single layer substrate. Results consistency with other studies, which are reported in literature, is discussed.

Download or read book Direct Numerical Simulation of Turbulent Flow and Heat Transfer in a Square Duct at Low Reynolds Number written by M. Piller and published by . This book was released on 2001 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper, we present the results from Direct Numerical Simulations of turbulent, incompressible flow through a square duct, with an imposed temperature difference between two opposite walls, while the other two walls are assumed perfectly insulated. The mean flow is sustained by an imposed, mean pressure gradient. The most interesting feature, characterizing this geometry, consists in the presence of turbulence-sustained mean secondary motions in the cross-flow plane. In this study, we focus on weak turbulence, in that the Reynolds number, based on bulk velocity and hydraulic diameter, is about 4450. Our results indicate that secondary motions do not affect dramatically the global parameters, like friction factor and Nusselt number, in comparison with the plane-channel flow. This issue is investigated by looking at the distribution of the various contributions to the total heat flux, with particular attention to the mean convective term, which does not appear in the plane channel flow.

Available in PDF, EPUB and Kindle. Book excerpt: Illustrates Calculations Using Machine and Technological Processes The conjugate heat transfer (CHT) problem addresses the thermal interaction between a body and fluid flowing over or through it. This is an essential consideration in nature and different areas of engineering, including mechanics, aerospace, nuclear engineering, biology, and meteorology. Advanced conjugate modeling of the heat transfer process is now used extensively in a wide range of applications. Conjugate Problems in Convective Heat Transfer addresses the latest theory, methods, and applications associated with both analytical and numerical methods of solution CHT problems and their exact and approximate solutions. It demonstrates how the true value of a CHT solution is derived by applying these solutions to contemporary engineering design analysis. Assembling cutting-edge information on modern modeling from more than 200 publications, this book presents more than 100 example applications in thermal treatment materials, machinery operation, and technological processes. Creating a practical review of current CHT development, the author includes methods associated with estimating heat transfer, particularly that from arbitrary non-isothermal surfaces in both laminar and turbulent flows. Harnesses the Modeling Power of CHT Unique in its consistent compilation and application of current knowledge, this book presents advanced CHT analysis as a powerful tool for modeling various device operations and technological processes, from relatively simple procedures to complex multistage, nonlinear processes.
