This book was released on 2009 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper, a generalized analytical equation for cooling time evaluation is analyzed and compared with existing exact solutions and verified by computation fluid dynamics (CFD) simulation. The process of quenching of semiaxles and cylindrical forgings in water flow is also considered. Two approaches are analyzed. The traditional approach focuses on quenching, which is based on Newton's boundary condition between the solid surface and fluid. The second approach solves a conjugate heat transfer problem based on a full set of Navier--Stokes equations. CFD technology does not require knowledge of the heat transfer coefficients at the surface of steel parts. Both approaches and results of calculations were compared and the results showed that a generalized correlation can be used for cooling time calculation both for simple and complicated configurations. Calculation results coincide with each other, which indicates that the generalized equation is a suitable method for calculations and development of intensive quenching technologies. As an example, the processes for quenching semi-axle and cylindrical forgings are considered. CFD analysis successfully detected small stagnant zones at the surface of the steel. Such zones could be related to quench crack formation. These results can be used for designing and development of intensive quenching processes.

Book Synopsis New Results in Numerical and Experimental Fluid Mechanics VII by : Andreas Dillmann
Download or read book New Results in Numerical and Experimental Fluid Mechanics VII written by Andreas Dillmann and published by Springer Science & Business Media. This book was released on 2010-10-05 with total page 629 pages. Available in PDF, EPUB and Kindle. Book excerpt: th This volume contains the papers presented at the 16 DGLR/STAB-Symposium held at the Eurogress Aachen and organized by RWTH Aachen University, Germany, November, 3 - 4, 2008. STAB is the German Aerospace Aerodynamics Association, founded towards the end of the 1970's, whereas DGLR is the German Society for Aeronautics and Astronautics (Deutsche Gesellschaft für Luft- und Raumfahrt - Lilienthal Oberth e.V.). The mission of STAB is to foster development and acceptance of the discipline “Aerodynamics” in Germany. One of its general guidelines is to concentrate resources and know-how in the involved institutions and to avoid duplication in research work as much as possible. Nowadays, this is more necessary than ever. The experience made in the past makes it easier now, to obtain new knowledge for solving today's and tomorrow's problems. STAB unites German scientists and engineers from universities, research-establishments and industry doing research and project work in numerical and experimental fluid mechanics and aerodynamics for aerospace and other applications. This has always been the basis of numerous common research activities sponsored by different funding agencies. Since 1986 the symposium has taken place at different locations in Germany every two years. In between STAB workshops regularly take place at the DLR in Göttingen.
Book Synopsis The Finite Volume Method in Computational Fluid Dynamics by : F. Moukalled
Download or read book The Finite Volume Method in Computational Fluid Dynamics written by F. Moukalled and published by Springer. This book was released on 2015-08-13 with total page 799 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook explores both the theoretical foundation of the Finite Volume Method (FVM) and its applications in Computational Fluid Dynamics (CFD). Readers will discover a thorough explanation of the FVM numerics and algorithms used for the simulation of incompressible and compressible fluid flows, along with a detailed examination of the components needed for the development of a collocated unstructured pressure-based CFD solver. Two particular CFD codes are explored. The first is uFVM, a three-dimensional unstructured pressure-based finite volume academic CFD code, implemented within Matlab. The second is OpenFOAM®, an open source framework used in the development of a range of CFD programs for the simulation of industrial scale flow problems. With over 220 figures, numerous examples and more than one hundred exercise on FVM numerics, programming, and applications, this textbook is suitable for use in an introductory course on the FVM, in an advanced course on numerics, and as a reference for CFD programmers and researchers.

Book Synopsis Temperature Calculation in Fire Safety Engineering by : Ulf Wickström
Download or read book Temperature Calculation in Fire Safety Engineering written by Ulf Wickström and published by Springer. This book was released on 2016-05-25 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a consistent scientific background to engineering calculation methods applicable to analyses of materials reaction-to-fire, as well as fire resistance of structures. Several new and unique formulas and diagrams which facilitate calculations are presented. It focuses on problems involving high temperature conditions and, in particular, defines boundary conditions in a suitable way for calculations. A large portion of the book is devoted to boundary conditions and measurements of thermal exposure by radiation and convection. The concepts and theories of adiabatic surface temperature and measurements of temperature with plate thermometers are thoroughly explained.Also presented is a renewed method for modeling compartment fires, with the resulting simple and accurate prediction tools for both pre- and post-flashover fires. The final chapters deal with temperature calculations in steel, concrete and timber structures exposed to standard time-temperature fire curves. Useful temperature calculation tools are included, and several examples demonstrate how the finite element code TASEF can be used to calculate temperature in various configurations. Temperature Calculation in Fire Safety Engineering is intended for researchers, students, teachers, and consultants in fire safety engineering. It is also suitable for others interested in analyzing and understanding fire, fire dynamics, and temperature development. Review questions and exercises are provided for instructor use.
