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.

This book was released on 1987 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: U.S. Air Force and other agencies which handle, store and transport chemicals, fuels and oxidizers are interested in determining the potential area of hazard posed by the dispersion of vapors generated by accidental spills. This report describes the mathematical models developed to described a variety of source types and the dispersion of vapor clouds/plumes in the atmosphere. Sixteen different source types are modeled including pressurized liquid releases, flashing and aerosol formation, two phase jet releases, explosive releases and releases of high vapor pressure liquids, cryogenic liquids and gases. Dispersion model takes into account the differences in source characteristics, high-than-air density of clouds (due to aerosol presence, temperature or molecular weight). Reactions of the chemicals, if any, .th water vapor in the air are modeled and considered in the dispersion model. Transition from heavy gas dispersion to near neutral density dispersion is modeled without abrupt changes in size or discontinuity in concentrations. Keywords: Heavy gas, Dispersion, Mathematical model, Reaction, Source models, Concentration contours.

Download or read book Development of an Atmospheric Dispersion Model for Heavier-Than-Air Gas Mixtures. Volume 2. Laboratory Calm Air Heavy Gas Dispersion Experiments written by Jerry A. Havens and published by . This book was released on 1985 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: Laboratory experimental instantaneous releases of right circular cylindrical volumes of heavy gas (Freon-12/air) with initial volumes ranging from 0.034 cu m to 0.531 cu m and specific gravities ranging from 2.2 to 4.2 are described. Releases with initial height-to-diameter ratios of 0.4, 1.0, and 1.57 are reported. The heavy gas flow field surrounding the release is described by time series of gas concentration at various radial and vertical coordinates with respect to release center. Measurements of the gravity current velocities are determined from time-of-onset of measured gas concentration. Calm-air instantaneous heavy gas releases are demonstrated to scale with a characteristic length cube root of V sub i where V sub i is the initial volume, and a characteristic time (V sub i to the 1/6 power)/(sq root of the reduced gravitational acceleration). The scaled laboratory releases predict the gravity-spreading and dilution process occurring during the buoyancy-dominated flow phase of the 2000 cu/m Freon/air instantaneous releases conducted by the British Health and Safety Executive at Thorney Island, UK. The gravity spread and dilution data are used to validate the buoyancy-dominated flow submodel which is incorporated in DEGADIS, the general purpose heavy gas dispersion model developed for the Coast Guard.

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.
