Navier-Stokes Turbulence: Theory and Analysis, Second Edition

Navier-Stokes Turbulence: Theory and Analysis, Second Edition by Wolfgang Kollmann
English | PDF EPUB (True) | 2024 | 876 Pages | ISBN : 3031595777 | 212.5 MB

This updated/augmented second edition retains it class-tested content and pedagogy as a core text for graduate courses in advanced fluid mechanics and applied science. The new edition adds revised sections, clarification, problems, and chapter extensions including a rewritten section on Schauder bases for turbulent pipe flow, coverage of Cantwell’s mixing length closure for turbulent pipe flow, and a section on the variational Hessian. Consisting of two parts, the first provides an introduction and general theory of fully developed turbulence, where treatment of turbulence is based on the linear functional equation derived by E. Hopf governing the characteristic functional that determines the statistical properties of a turbulent flow. In this section, Professor Kollmann explains how the theory is built on divergence free Schauder bases for the phase space of the turbulent flow and the space of argument vector fields for the characteristic functional. The second segment, presented over subsequent chapters, is devoted to mapping methods, homogeneous turbulence based upon the hypotheses of Kolmogorov and Onsager, intermittency, structural features of turbulent shear flows and their recognition.

Modeling and Simulation of Fluidized Bed Reactors for Chemical Looping Combustion

Modeling and Simulation of Fluidized Bed Reactors for Chemical Looping Combustion by Ramesh K. Agarwal , Yali Shao
English | PDF EPUB (True) | 2024 | 236 Pages | ISBN : 3031113349 | 61.5 MB

The book describes the clean coal technology of chemical looping combustion (CLC) for power generation with pure CO2 capture. The focus of the book is on the modeling and simulation of CLC. It includes fundamental concepts behind CLC and considers all categories of fluidized beds and reactors, including a variety of oxygen carriers. The book includes process simulations with Aspen Plus® software using coal, natural gas, and biomass and computational fluid dynamics (CFD) simulations using both the Eulerian and Lagrangian methods. It describes various drag models, turbulence models, and kinetics models required for CFD simulations of CLC and covers single reactor, partial, and full-simulations, single/multi-stage as well as single-particle simulations, and CLC with reverse flow. A large number of examples for both process simulations using Aspen Plus and CFD simulations using a variety of fluidized beds/reactors employing both the two-fluid and Computational Fluid Dynamics / Discrete Element Method (CFD-DEM) model are provided.

International Symposium on History of Machines and Mechanisms: Proceedings HMM2004 by Marco Ceccarelli
English | PDF | 2004 | 408 Pages | ISBN : 1402022034 | 21.3 MB

The HMM2004 International Symposium on History of Machines and Mechanisms is the second event of a series that has been started in 2000 as main activity of the IFToMM Permanent Commission for History of MMS, Mechanism and Machine Science. The aim of the HMM Symposium is to be a forum to exchange views, opinions, and experiences on History of MMS from technical viewpoints in order to track the past but also to look at future developments in MMS.
