Book excerpt: The motions of droplets on fibers are important to many industrial applications. In particular, the movements of drops control the performance of fibrous filters. Fibrous filters are widely used in the petrochemical industries to separate aerosol droplets from air to protect the environment and worker health. The performance of a filter medium depends on factors like fiber size, droplet, face velocity, liquid properties and gas conditions. In the operation of a fibrous filter, the droplets carried by a flowing gas are captured by the filter medium due to collisions with the fibers of the medium. Liquid droplets can deform when forces are applied and, when captured on fibers, the droplets can spread over the fiber surface, coalesce into larger drops, and can migrate within the filter as drops or as a flowing film. The movements of the drops on the fibers after they are captured require study to develop theory, correlations, and data to validate models. The overall goal of this dissertation work is to develop new generalized theory for design and manufacture of gas-liquid separation media by developing correlations for gas flow conditions and movements of liquid drops in fibrous media. These relationships will enable the design and development of the next generation of fibrous filtration/separation media with superior performance.There are four experimental tasks to achieve this goal. Experiments on droplet interactions with single fibers, crossing fibers, thin and thick mats. These experiments were conducted to study the shape and migration of drops on fibers and provide fundamental understanding and insight as to how drops attach to, move on and detach from fibers. Different liquids with different drop sizes were tested that give a range of contact angles on the fibers. Different fiber materials with different fiber diameters were evaluated that give a range of surface properties. The liquids, fibers materials and sizes, and droplet sizes were selected as those currently of interest to the filter testing community.
Book Synopsis Aerosol Filtration by : Dominique Thomas
Download or read book Aerosol Filtration written by Dominique Thomas and published by Elsevier. This book was released on 2016-11-30 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Filtration of aerosols is omnipresent in our daily lives, in areas as diverse as health, the protection of people and the environment, and air treatment inside buildings. However, the collection of particles within a filter media is not, contrary to popular belief, linked to a simple screen effect. The phenomena involved are much more complex and require the consideration of aerosol interactions, filter media and process conditions to select the best fiber filter for a given application. Aerosol Filtration, book for students, hygiene or process engineers, fibrous media manufacturers, designers, and filtration system suppliers or users addresses the filtration of aerosols in six chapters. These chapters cover physics and aerosol characterization, the fibrous media, and efficiency and filter clogging by solid or liquid aerosols, with special attention to the filtration of the nanoparticles. - Analyses the behavior of fibrous media against solid and liquid aerosols - Presents models of efficiency and pressure drop - Introduces computing elements for estimating the lifetime of filters - Provides guidance for designing filters and predicting their behavior over time
Book Synopsis Microscale Study of Drop Migration on Fibers in Coalescing Filters by : Saru Dawar
Download or read book Microscale Study of Drop Migration on Fibers in Coalescing Filters written by Saru Dawar and published by . This book was released on 2007 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The micro scale study of drop motion on fibers is significant to many industrial applications such as drop coalescence and drainage in fibrous filter media. Removal of the liquid droplets from the exhaust streams of many chemical, automotive, aeronautics, textile and health and safety industries is of vital importance. These droplets can lead to clogging of the fibrous filters during the cleaning operation. It is significant to design a self cleaning filter, whereby the liquid droplets collect on the filter and drain down onto some collecting device. This reduces the operational and cleaning cost of the filter. The underlying need for all these applications is estimation of the velocity of a drop along the fiber axis. This can be done by defining and determining the drag coefficient correlation. In this work, the drag coefficient is correlated to Reynolds and capillary numbers from experiments and models with the axial and transverse air flow conditions. The experiments are conducted for different types of fibers and using acoustic fields. Correlations to predict the probability of the motion of the drops on fibers are also developed considering the effect of acoustic fields. These correlations are unique approach to determine the velocities of the liquid drops on fibers for different fiber orientations. Very little has been published on the development of such correlations to predict drop migration on fibers which makes this work unique."--Abstract.

Available in PDF, EPUB and Kindle. Book excerpt: This book documents the proceedings of the Symposium on Particles in Fluids: Detection, Characterization and Control held as a part of the 18th Fine Particle Society meeting in Boston, August 3-7, 1987. This was the Premier symposium on this topic and the response was so good that we have decided to organize it on a biennial basis and the second symposium will be held under the rubric Particles in Gases and Liquids: Detection, Characterization and Control at the 20th Fine Particle Society meeting in Boston, August 22-26, 1989. In the modern manufacture of sophisticated and sensitive microelectronic components and other precision parts, there has been a great deal of concern about yield losses due to micrometer- and submicrometer-sized particles. These particles can originate from a number of sources including fluids, i. e. , gases and liquids used in the manufacturing process. So the detection, characterization and control or removal of these undesirable particles is of cardinal importance and this symposium was conceived and o~ganized with this in mind. The purposes of this symposium were to bring together those actively involved in all aspects of particles in fluids, to provide a forum for discussion of the latest techniques for the detection, characterization and control of particles, and to highlight areas which needed intensified R&D efforts. The printed program contained a total of 46 papers and a variety of topics dealing with various ramifications of particles in fluids were presented.

Book excerpt: AEROSOL SCIENCE TECHNOLOGY AND APPLICATIONS Aerosols influence many areas of our daily life. They are at the core of environmental problems such as global warming, photochemical smog and poor air quality. They can also have diverse effects on human health, where exposure occurs in both outdoor and indoor environments. However, aerosols can have beneficial effects too; the delivery of drugs to the lungs, the delivery of fuels for combustion and the production of nanomaterials all rely on aerosols. Advances in particle measurement technologies have made it possible to take advantage of rapid changes in both particle size and concentration. Likewise, aerosols can now be produced in a controlled fashion. Reviewing many technological applications together with the current scientific status of aerosol modelling and measurements, this book includes: Satellite aerosol remote sensing The effects of aerosols on climate change Air pollution and health Pharmaceutical aerosols and pulmonary drug delivery Bioaerosols and hospital infections Particle emissions from vehicles The safety of emerging nanomaterials Radioactive aerosols: tracers of atmospheric processes With the importance of this topic brought to the public's attention after the eruption of the Icelandic volcano Eyjafjallajökull, this book provides a timely, concise and accessible overview of the many facets of aerosol science.
