Available in PDF, EPUB and Kindle. Book excerpt: This book provides a theoretical description of the liquid atomization and spray formation. It is the first in series of books on droplets, sprays and aerosol. The atomization process is a combination of several different liquid breakup processes. It involves of the formation of waves on the liquid surface, which are generated by a variety of effects, such as by the large relative velocity between the liquid and its surrounding gas. The waves may grow in amplitude, stretch out of the core liquid flow, and eventually breakup into cylindrical or sheet-like ligaments. Liquid ligaments may become unstable and breakup into droplets. Droplets may deform and breakup into smaller droplets by the drag forces or by collision with other droplets or solid surfaces. The physical principal behind the above processes can be simplified into several liquid instability processes. These include instabilities of liquid sheets, jets, and droplets. These instabilities are mainly governed by Kelvin-Helmholtz, Rayleigh-Plateau, and Rayleigh-Taylor instabilities, which respectively come about due to a velocity difference between the liquid and its surrounding gas; due to capillary forces, and by the acceleration of one fluid onto the other. Droplet-droplet collisions and droplet impact on solid surfaces are two other important processes that occur in sprays. Droplets may coalesce after collision forming larger droplets or breakup into smaller droplets. Phenomenological models are used to provide droplet sizes that emerge. Similarly, when a droplet impacts on a solid surface, it may spread, splash, or bounce off. Models for the relevant outcomes to atomization are provided for this process. Finally, the atomization processes is modeled by combining various instability theories to obtain characteristic droplet sizes for different types of spray.

Book excerpt: Providing a clear and systematic description of droplets and spray dynamic models, this book maximises reader insight into the underlying physics of the processes involved, outlines the development of new physical and mathematical models and broadens understanding of interactions between the complex physical processes which take place in sprays. Complementing approaches based on the direct application of computational fluid dynamics (CFD), Droplets and Sprays treats both theoretical and practical aspects of internal combustion engine process such as the direct injection of liquid fuel, subcritical heating and evaporation. Including case studies that illustrate the approaches relevance to automotive applications, it is also anticipated that the described models can find use in other areas such as in medicine and environmental science.

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.

Book excerpt: Technically, an aerosol is a suspension of fine solid particles or liquid droplets in a gas. Examples are smoke, oceanic haze, air pollution, smog and CS gas. In general conversation, "aerosol" usually refers to an aerosol spray can or the output of such a can. The word aerosol derives from the fact that matter "floating" in air is a suspension (a mixture in which solid or liquid or combined solid-liquid particles are suspended in a fluid). To differentiate suspensions from true solutions, the term sol evolved -- originally meant to cover dispersions of tiny (sub-microscopic) particles in a liquid. With studies of dispersions in air, the term aerosol evolved and now embraces both liquid droplets, solid particles, and combinations of these. An aerosol may come from sources as various as a volcano or an aerosol can. this book focuses on the chemistry, environmental impact and health effects of aerosols.

Book excerpt: This textbook aims to be a one stop shop for those interested in aerosols and their impact on the climate system. It starts with some fundamentals on atmospheric aerosols, atmospheric radiation and cloud physics, then goes into techniques used for in-situ and remote sensing measurements of aerosols, data assimilation, and discusses aerosol-radiation interactions, aerosol-cloud interactions and the multiple impacts of aerosols on the climate system. The book aims to engage those interested in aerosols and their impacts on the climate system: graduate and PhD students, but also post-doctorate fellows who are new to the field or would like to broaden their knowledge. The book includes exercises at the end of most chapters. Atmospheric aerosols are small (microscopic) particles in suspension in the atmosphere, which play multiple roles in the climate system. They interact with the energy budget through scattering and absorption of solar and terrestrial radiation. They also serve as cloud condensation and ice nuclei with impacts on the formation, evolution and properties of clouds. Finally aerosols also interact with some biogeochemical cycles. Anthropogenic emissions of aerosols are responsible for a cooling effect that has masked part of the warming due to the increased greenhouse effect since pre-industrial time. Natural aerosols also respond to climate changes as shown by observations of past climates and modelling of the future climate.

Available in PDF, EPUB and Kindle. Book excerpt: A bioaerosol is a colloidal suspension of liquid droplets or solid particles in air whose components contain or have attached to them one or more microorganisms. Bioaerosols are an exciting and vital object of study because the attached microbes play a critical role in human, animal and environmental health. In an era of genetically engineered microorganisms and the application of biopesticides, bioaerosols are increasingly an environmental problem, both indoors and outdoors, and can affect entire ecosystems. Atmospheric Microbial Aerosols examines naturally occuring bioaerosols, as well as bioaerosols generated by human activity. Included in this volume is a complete array of topics concerned with outdoor microbial bioaerosols ranging from the physical and chemical to the meteorological and microbial. It will be of great interest as a starting point for researchers interested in outdoor microbial bioaerosols as well as for those interested in atmospheric dispersion models, new equipment, and government regulations.
