Download or read book Topics in Current Aerosol Research written by G. M. Hidy and published by Elsevier. This book was released on 2013-10-22 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Topics in Current Aerosol Research deals with the fundamental aspects of aerosol science, with emphasis on experiment and theory describing highly dispersed aerosols (HDAs) as well as the dynamics of charged suspensions. Topics covered range from the basic properties of HDAs to their formation and methods of generation; sources of electric charges; interactions between fluid and aerosol particles; and one-dimensional motion of charged cloud of particles. This volume is comprised of 13 chapters and begins with an introduction to the basic properties of HDAs, followed by a discussion on the formation of condensation HDAs. Some of the methods of generation of HDAs are considered, including atomization, physical condensation of vapor, and chemical reactions in the gas phase are considered. A ""transport"" model for electrically charged aerosols is described. Subsequent chapters explore methods of investigation of HDAs in suspended state and based on particle precipitation; transfer processes in HDAs, including mass transfer, charge transfer, momentum transfer, and heat transfer; and charging of particulate matter by collection. This book will be a useful resource for practicing scientists and graduate students in such widely diverse fields as physics, physical chemistry, meteorology, geophysics, astronomy, chemical engineering, mechanical engineering, aerospace engineering, environmental sciences, and medicine.

Download or read book Modeling Atmospheric Secondary Organic Aerosol Dynamics Through Chemistry Emissions and Partition Theory written by Wayne Li-wen Chang and published by . This book was released on 2011 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: The detrimental impact on both human health and global climate of atmospheric particular matter (PM) is now well-established. Among the various classifications of PM, a significant portion is comprised of secondary organic aerosol (SOA). Despite its importance, there are still much uncertainty regarding the formation and evolution of SOA in the atmosphere, beginning with the oxidation of organic gases that leads to semi-volatile and low volatility products. The need to further improve the current knowledge SOA is made apparent by the observed large discrepancy between model predictions and field measurements of SOA. Proposed explanations behind the orders of magnitude underprediction of ambient SOA levels by state-of-the-art airshed models include: missing particle-forming oxidized organic products, unidentified SOA precursor emissions, and issues related to the fundamentals of current SOA partition theory, all of which are considered in this study to develop corresponding improvements to the latest airshed models. The model used in this study is the UCI-CIT airshed model, and the improvement scenario tests are set in the urban region of South Coast Air Basin of California. Recent chamber results have shown that the original implementation of alkane-derived SOA provided an underestimate for what was likely to be occurring in urban atmospheres. Thus, the original chemical mechanism is revised to include higher generation products of medium- and long-chain alkanes that can contribute to SOA in this study. Primary organic aerosol (POA) has been identified to be able to evaporate with dilution; therefore, test cases are developed that treat fractions of POA as semi-volatile, a source of SOA, rather than nonvolatile. While current atmospheric models assume that SOA are liquids into which semi-VOCs undergo equilibrium partitioning and grow the particles, recent laboratory and field experiments have shown otherwise. Hence, a new kinetics-driven partition theory is developed and analyzed against the original formulations. The results from the expanded chemical mechanism to include higher-generation products of alkane in the atmosphere shows that only the tetrahydrofurans will contribute to SOA and those contributions are only a small fraction compared to other SOA sources in the model, contrary to the prediction made based on chamber experiments and box models. In the tests for redistribution of POA as gas-phase parent VOCs sources, POA decreased with no commensurate increase in SOA. This is essentially due to the fact that the amount of mass that the POA can contribute is a small fraction of that already in the gas-phase parent VOC pool. Finally, using the newly developed kinetically determined SOA growth mechanism, to achieve the same level of predicted SOA levels as the original equilibrium approach requires 40-50% of SOA parent species to be allocated to the particle phase. The new formulation of SOA partition behavior based on kinetics will require the measurement of new input data and the corresponding parameterization for models in the future. The implication of this new approach should demand wider attention from the community.

Book excerpt: Aerosols have a significant impact on technological processes and human activities. In many cases, aerosols are at the core of human health, environmental and technological problems (climate change and air quality). However, aerosols can be successfully used in industry and technology (new materials, fire suppression and fuel delivery). The current scientific status of aerosol modelling and simulation and measurements and some advances in computational techniques, particle measurement technologies and practical applications of aerosols are reviewed and considered in this book. This book also includes a number of case studies focused on analysis of optical thickness and air quality in various regions.

Book excerpt: The ever-diversifying field of aerosol effects on climate is comprehensively presented here, describing the strong connection between fundamental research and model applications in a way that will allow both experienced researchers and those new to the field to gain an understanding of a wide range of topics. The material is consistently presented at three levels for each topic: (i) an accessible "quick read" of the essentials, (ii) a more detailed description, and (iii) a section dedicated to how the processes are handled in models. The modelling section in each chapter summarizes the current level of knowledge and what the gaps in this understanding mean for the effects of aerosols on climate, enabling readers to quickly understand how new research fits into established knowledge. Definitions, case studies, reference data, and examples are included throughout. Aerosols and Climate is a vital resource for graduate students, postdoctoral researchers, senior researchers, and lecturers in departments of atmospheric science, meteorology, engineering, and environment. It will also be of interest to those working in operational centers and policy-facing organizations, providing strong reference material on the current state of knowledge. Includes a section in each chapter that focuses on the treatment of relevant aerosol processes in climate models Provides clear exposition of the challenges in understanding and reducing persistent gaps in knowledge and uncertainties in the field of aerosol-climate interaction, going beyond the fundamentals and existing knowledge Authored by experts in modeling and aerosol processes, analysis or observations to ensure accessibility and balance

This book was released on 2011-03-27 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aerosols play a critical role in a broad range of scientific disciplines, such as atmospheric chemistry and physics, combustion science, drug delivery and human health. This thesis explores the fundamentals of a new technique for capturing single or multiple particles using light, and for characterising these particles by Raman or fluorescence spectroscopy. The outcome of this research represents a significant development in optical manipulation techniques, specifically in optical tweezing. These findings can be applied to studies of the mass accommodation of gas-phase water molecules adsorbing onto a water surface. Not only is this a fundamental process of interest to physical chemists, but it is important for understanding the role of aerosol particles in the atmosphere, including their ability to become cloud droplets. This new strategy for investigating aerosol dynamics is fundamental in helping us understand the indirect effect of aerosols on the climate.
