Available in PDF, EPUB and Kindle. Book excerpt: A wind tunnel model was used to study stack plume dispersion at a surface-mining site. The interaction between plumes and the wake flows behind the stacks and large terrain obstacles (dikes) was investigated. Mean flow Reynolds number was about 25,000 times smaller in the wind tunnel than in the full scale atmospheric flow, affecting the dynamic similarity of the model. Stack wake flows were found to model downwash effects properly despite Reynolds number mismatch, as indicated by measured values of base pressure coefficient, -Cp^ - 0.86, for cylinders at model conditions, which were close to values from Roshko (1960) for cylinder flows at full scale Reynolds numbers. However, model dikes were found to greatly exaggerate the size of recirculation zones and influence of the dike wake flows on downwind velocity and turbulence levels. This problem was corrected using a deflector vane mounted on the model dike crests. A combined-rise formulation was developed which predicts both the momentum and buoyancy effect on plume rise. Momentum rise entrainment constants, predicted from a simple model from Wilson (unpublished) were found to yield accurate momentum rise predictions using the combined-rise formulation. Buoyancy rise entrainment constants $2 were found to vary realistically with changing flow conditions. The momentum flux ratio d).. was found to be well correlated with stack downwash effects, providing a means of prediction for this phenomenon. Dike wakes were found to increase measured ground level concentrations (GLC) from plumes, with a non-linear degree of severity with dike height. The Gaussian dispersion model was found to be adequate in predicting GLC. A correction model was proposed to account for dike effects on GLC through increased vertical plume spread o in the Gaussian model.

This book was released on 2013-03-14 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 24 (thesis year 1979) a total of 10,033 theses titles from 26 Canadian and 215 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. While Volume 24 reports these submitted in 1979, on occasion, certain universities do report theses submitted in previous years but not reported at the time.

Download or read book Deep Sea Mining written by Rahul Sharma and published by Springer. This book was released on 2017-03-28 with total page 535 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive book contains contributions from specialists who provide a complete status update along with outstanding issues encompassing different topics related to deep-sea mining. Interest in exploration and exploitation of deep-sea minerals is seeing a revival due to diminishing grades and increasing costs of processing of terrestrial minerals as well as availability of several strategic metals in seabed mineral resources; it therefore becomes imperative to take stock of various issues related to deep-sea mining. The authors are experienced scientists and engineers from around the globe developing advanced technologies for mining and metallurgical extraction as well as performing deep sea exploration for several decades. They invite readers to learn about the resource potential of different deep-sea minerals, design considerations and development of mining systems, and the potential environmental impacts of mining in international waters.

Download or read book Spills of Diluted Bitumen from Pipelines written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2016-03-22 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diluted bitumen has been transported by pipeline in the United States for more than 40 years, with the amount increasing recently as a result of improved extraction technologies and resulting increases in production and exportation of Canadian diluted bitumen. The increased importation of Canadian diluted bitumen to the United States has strained the existing pipeline capacity and contributed to the expansion of pipeline mileage over the past 5 years. Although rising North American crude oil production has resulted in greater transport of crude oil by rail or tanker, oil pipelines continue to deliver the vast majority of crude oil supplies to U.S. refineries. Spills of Diluted Bitumen from Pipelines examines the current state of knowledge and identifies the relevant properties and characteristics of the transport, fate, and effects of diluted bitumen and commonly transported crude oils when spilled in the environment. This report assesses whether the differences between properties of diluted bitumen and those of other commonly transported crude oils warrant modifications to the regulations governing spill response plans and cleanup. Given the nature of pipeline operations, response planning, and the oil industry, the recommendations outlined in this study are broadly applicable to other modes of transportation as well.

This book was released on 2015-05-09 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout the mining and processing of minerals, the mined ore undergoes a number of crushing, grinding, cleaning, drying, and product sizing operations as it is processed into a marketable commodity. These operations are highly mechanized, and both individually and collectively these processes can generate large amounts of dust. If control technologies are inadequate, hazardous levels of respirable dust may be liberated into the work environment, potentially exposing workers. Accordingly, federal regulations are in place to limit the respirable dust exposure of mine workers. Engineering controls are implemented in mining operations in an effort to reduce dust generation and limit worker exposure.

This book was released on 2000-10-21 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Incineration has been used widely for waste disposal, including household, hazardous, and medical wasteâ€"but there is increasing public concern over the benefits of combusting the waste versus the health risk from pollutants emitted during combustion. Waste Incineration and Public Health informs the emerging debate with the most up-to-date information available on incineration, pollution, and human healthâ€"along with expert conclusions and recommendations for further research and improvement of such areas as risk communication. The committee provides details on: Processes involved in incineration and how contaminants are released. Environmental dynamics of contaminants and routes of human exposure. Tools and approaches for assessing possible human health effects. Scientific concerns pertinent to future regulatory actions. The book also examines some of the social, psychological, and economic factors that affect the communities where incineration takes place and addresses the problem of uncertainty and variation in predicting the health effects of incineration processes.
