Download or read book Development of an Atmospheric Dispersion Model for Heavier Than Air Gas Mixtures written by Jerry A. Havens and published by . This book was released on 1985 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mathematical modeling techniques use to predict atmospheric dispersion of heavy gases are reviewed and critiqued. These dispersion processes are characterized by three phases: (1) near field, negative buoyancy-domainated flow regime; (2) intermediate field, stably stratified shear flow regime; and (3) far field, passive turbulent diffusion regime. Mathematical models of laboratory and natural gravity currents are used to describe the negative buoyancy-dominated regime flow and dilution processes. A laboratory investigation of instantaneous heavy gas releases in calm air demonstrates scaling from small release volumes (0.5 cu m) to large field (2000 cu m) field releases, and is used to develop a mathematical model for the buoyancy-dominated regime. Laboratory data from stratified shear flow mixing experiments are used to develop a model for vertical diffusion of heavy gases in the atmospheric surface layer. The model concepts are consistent with the limiting passive behavior of demonstrated air pollution models. An interactive computer model for heavy gas dispersion (DEGADIS) is developed. The DEGADIS model accounts for the three regimes of heavy gas dispersion processes and can be used to simulate instantaneous, steady state, and transient releases. The model provides predictions of downwind concentration decay which are in good agreement with the full range of field experimental data currently available, and is recommended for incorporation in the Coast Guard hazard assessment computer system.

Download or read book Integrated Regional Risk Assessment Vol II written by A.V. Gheorghe and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over recent years there has been an increasing awareness of the risks of locating hazardous industries near heavily populated, environmentally sensitive areas. This new awareness demands a novel approach to safety planning for hazardous industries; one that looks at the problem from the point of view of integrated regional risk assessment which, besides the risks arising from natural events, should also include the risks arising from the processing plants, storage and the transportation of dangerous goods. Volume I of Integrated Regional Risk Assessment highlights the main procedures for the assessment of risks to health and environmental impacts from continuous emissions of pollutants into air, water and soil under normal operating conditions. Volume II deals with the assessment of consequences of accidental releases, helping to answer such questions as: What can go wrong? What are the effects and consequences? How often will it happen? £/LIST£ The main procedural steps are supported by relevant, internationally recognised methods of risk assessment. The book also reviews criteria and guidelines for the implementation of risk assessment and management at different stages. Audience: Students, engineers, and scientists in charge of developing new methodologies for hazard analysis and risk assessment; practitioners of environmental protection; local and governmental authorities charged with implementing environmental risk impact procedures and guidelines.

Download or read book LNG Risk Based Safety written by John L. Woodward and published by John Wiley & Sons. This book was released on 2010-03-25 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: The expert, all-inclusive guide on LNG risk based safety Liquefied Natural Gas (LNG) is the condensed form of natural gas achieved by cryogenic chilling. This process reduces gas to a liquid 600 times smaller in volume than it is in its original state, making it suitable for economical global transportation. LNG has been traded internationally and used with a good safety record since the 1960s. However, with some accidents occurring with the storage and liquefaction of LNG, a good understanding of its mechanisms, and its potential ramifications to facilities and to the nearby public, is becoming critically important. With an unbiased eye, this book leans on the expertise of its authors and LNG professionals worldwide to examine these serious safety issues, while addressing many false assumptions surrounding this volatile energy source. LNG Risk Based Safety: Summarizes the findings of the Governmental Accountability Office's (GAO) survey of nineteen LNG experts from across North America and Europe Reviews the history of LNG technology developments Systematically reviews the various consequences from LNG releases— discharge, evaporation, dispersion, fire, and other impacts, and identifies best current approaches to model possible consequence zones Includes discussion of case studies and LNG-related accidents over the past fifty years Covering every aspect of this controversial topic, LNG Risk Based Safety informs the reader with firm conclusions based on highly credible investigation, and offers practical recommendations that researchers and developers can apply to reduce hazards and extend LNG technology.

Book excerpt: This is the first book that reviews problems in different fluid mechanics disciplines that led to the concept of canopy, or penetrable roughness. Despite their diversity, many flows may be theoretically united by means of introducing distributed sinks and/or sources of momentum and heat and mass. These and other flows in engineering and environmental situations over surfaces with many obstacles are reviewed in terms of general concepts of fluid mechanics.

This book was released on 2010-09-07 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second edition of this essential reference updates and combines two earlier titles to capture the many technological advances for predicting the "footprint" of a vapor cloud release. Cited by EPA in its 1996 document, "Off-Site Consequence Analysis Guidance," the aim of the book is to encourage and facilitate the development and use of dispersion modeling as an everyday tool, providing practical understanding of basic physical and chemical principles, guidance in selecting release scenarios and the best available models, and information and examples on how to run some models and interpret outputs. Equally useful to beginners and experts, it compares 22 programs based on input from model developers, and presents 7 examples of typical accidental release scenarios. The book comes with a disk providing input and output data for scenarios.

Download or read book Recent Research Advances in the Fluid Mechanics of Turbulent Jets and Plumes written by P.A. Davies and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: Challenging problems involvrllg jet and plume phenomena are common to many areas of fundamental and applied scientific research, and an understanding of plume and jet behaviour is essential in many geophysical and industrial contexts. For example, in the field of meteorology, where pollutant dispersal takes place by means of atmospheric jets and plumes formed either naturally under conditions of convectively-driven flow in the atmospheric boundary layer, or anthropogenically by the release of pollutants from tall chimneys. In other fields of geophysics, buoyant plumes and jets are known to play important roles in oceanic mixing processes, both at the relatively large scale (as in deep water formation by convective sinking) and at the relatively small scale (as with plume formation beneath ice leads, for example). In the industrial context, the performances of many engineering systems are determined primarily by the behaviour of buoyant plumes and jets. For example, (i) in sea outfalls, where either sewage or thermal effluents are discharged into marine and/or freshwater environments, (ii) in solar ponds, where buoyant jets are released under density interfaces, (iii) in buildings, where thermally-generated plumes affect the air quality and ventilation properties of architectural environments, (iv) in rotating machinery where fluid jet~ are used for cooling purposes, and (v) in long road and rail tunnels, where safety and ventilation prcedures rely upon an understanding of the behaviour of buoyant jets. In many other engineering and oceanographic contexts, the properties of jets and plumes are of great importance.
