Book excerpt: This book sets down the fundamentals of the theory and measurement of building ventilation and describes the various techniques for predicting and measuring ventilation. It addresses both envelope flows and internal air motion. The first part of the book is primarily concerned with physical descriptions and theoretical models: starting with an overview of the basic mechanisms and characteristics of envelope flows, it then addresses the treatment of the flow characteristics of individual openings and mathematical models for complete building envelopes. Theories for internal air motion are then discussed in detail: mechanisms of mass transport in terms of air motion and age distribution, primary air flows in isolation, resulting flows in enclosed spaces, and flows through large internal openings. The second part, concerned with measurement techniques both at full scale and at model scale, begins with techniques for determining flow characteristics of envelope openings. The use of tracer gases in the study of age distribution and ventilation efficiency is dealt with in detail. Scale modelling for investigating both envelope flows and internal motions is also addressed. The final chapter deals with Computational Fluid Dynamics, since one of its main applications is an alternative to conventional experimental techniques. Natural ventilation is re-emerging as an alternative to mechanical systems in some commercial buildings and both natural and mechanical ventilation are dealt with in detail.
Download or read book Ventilation of Buildings written by H.B. Awbi and published by Routledge. This book was released on 2004-06-02 with total page 537 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hazim Awbi's Ventilation of Buildings has become established as the definitive text on the subject. This new, thoroughly revised, edition builds on the basic principles of the original text drawing in the results of considerable new research in the field. A new chapter on natural ventilation is also added and recent developments in ventilation concepts and room air distribution are also considered. The text is intended for the practitioner in the building services industry, the architect, the postgraduate student undertaking courses or research in HVAC, building services engineering, or building environmental engineering, and the undergraduate studying building services as a major subject. Readers are assumed to be familiar with the basic principles of fluid flow and heat transfer and some of the material requires more advanced knowledge of partial differential equations which describe the turbulent flow and heat transfer processes of fluids. The book is both a presentation of the practical issues that are needed for modern ventilation system design and a survey of recent developments in the subject

Download or read book Elementary Buoyancy driven Ventilation written by Karl Terpager Andersen and published by . This book was released on 2019-01-04 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Buoyancy-driven ventilation is a part of natural ventilation, where wind forces may participate, but only buoyancy-driven ventilation (i.e. driven by the difference between outdoor and indoor air density) is considered in this book. The buoyancy-driven part is to some extent complicated from a theoretical point of view and requires a well-founded theory based on the fundamental flow equations to ensure reliable results. In the book, a model is set up for a room with two openings to the surroundings and with a uniform indoor temperature. From this basic model, variants are developed for rooms with several openings and/or with a stratified indoor temperature. Further, for each variant, versions are set up where the difference between outdoor and indoor air density, or the difference between the indoor and outdoor temperature, or the net heat input rate is the independent thermal variable. The scope of application is determined, and the opening area ratios are analysed with the aim to obtain optimal ventilation conditions. The book is of interest for building engineers who are or want to specialise in natural ventilation, to under-graduates who wish to have natural ventilation as their special subject, and to postgraduates who work with subjects where it is relevant to involve buoyancy-driven ventilation. For undergraduates in general, especially Chapters 2 and 3 are of interest.
Download or read book Buoyancy Driven Flows written by Eric P. Chassignet and published by Cambridge University Press. This book was released on 2012-03-05 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: Buoyancy is one of the main forces driving flows on our planet, especially in the oceans and atmosphere. These flows range from buoyant coastal currents to dense overflows in the ocean, and from avalanches to volcanic pyroclastic flows on the Earth's surface. This book brings together contributions by leading world scientists to summarize our present theoretical, observational, experimental and modeling understanding of buoyancy-driven flows. Buoyancy-driven currents play a key role in the global ocean circulation and in climate variability through their impact on deep-water formation. Buoyancy-driven currents are also primarily responsible for the redistribution of fresh water throughout the world's oceans. This book is an invaluable resource for advanced students and researchers in oceanography, geophysical fluid dynamics, atmospheric science and the wider Earth sciences who need a state-of-the-art reference on buoyancy-driven flows.

This book was released on 2015-07-14 with total page 445 pages. Available in PDF, EPUB and Kindle. 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.

Download or read book Natural Ventilation in the Urban Environment written by Francis Allard and published by Earthscan. This book was released on 2012-06-25 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout the world, there is an increasing interest in ecological design of buildings, and natural ventilation has proved to be the most efficient low-energy cooling technique. Its practical application, however, is hindered by the lack of information on the complex relationship between the building and its urban environment. In this book, a team of experts provide first-hand information and tools on the efficient use of natural ventilation in urban buildings. Key design principles are explained, enabling readers to decide on the best solution for natural ventilation of buildings, taking into account climate and urban context. In the initial sketches, architects need answers to open problems such as 'what kind of solution to adopt' and 'how to modify existing strategies to exploit the potential of the site'. This book formalizes the multi-criteria analysis of candidate solutions based on quantitative and qualitative estimation of the driving forces (wind and buoyancy), as well as of the barriers induced by the urban environment (wind speed reduction, noise and pollution) and gives a methodology for optimal design of openings. The book is accompanied by a FREE CD, containing software for assessing the potential of a given site, estimating wind speed and dimensioning the openings for natural ventilation. The methodologies and tools are tested, self-contained and user friendly. About the editors The editors, Cristian Ghiaus and Francis Allard, are affiliated with the University of La Rochelle, France. The authors and reviewers combine expertise from universities, research institutions and industry in Belgium, France, Great Britain, Greece, Portugal and Switzerland.

Book excerpt: This guide sets out recommendations for every phase of the planning, construction and operation of natural ventilation systems in these buildings, including local climatic factors that need to be taken into account, how to plan for seasonal variations in weather, and the risks in adopting different implementation strategies. All of the recommendations are based on analysis of the research findings from richly-illustrated international case studies. This is the first technical guide from the Council on Tall Buildings and Urban Habitat's Tall Buildings & Sustainability Working Group looking in depth at a key element in the creation of tall buildings with a much-reduced environmental impact, while taking the industry closer to an appreciation of what constitutes a sustainable tall building, and what factors affect the sustainability threshold for tall.
Download or read book Direct and Large Eddy Simulation XI written by Maria Vittoria Salvetti and published by Springer. This book was released on 2019-02-02 with total page 608 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gathers the proceedings of the 11th workshop on Direct and Large Eddy Simulation (DLES), which was held in Pisa, Italy in May 2017. The event focused on modern techniques for simulating turbulent flows based on the partial or full resolution of the instantaneous turbulent flow structures, as Direct Numerical Simulation (DNS), Large-Eddy Simulation (LES) or hybrid models based on a combination of LES and RANS approaches. In light of the growing capacities of modern computers, these approaches have been gaining more and more interest over the years and will undoubtedly be developed and applied further. The workshop offered a unique opportunity to establish a state-of-the-art of DNS, LES and related techniques for the computation and modeling of turbulent and transitional flows and to discuss about recent advances and applications. This volume contains most of the contributed papers, which were submitted and further reviewed for publication. They cover advances in computational techniques, SGS modeling, boundary conditions, post-processing and data analysis, and applications in several fields, namely multiphase and reactive flows, convection and heat transfer, compressible flows, aerodynamics of airfoils and wings, bluff-body and separated flows, internal flows and wall turbulence and other complex flows.
