This book was released on 2004 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the small fuel and air channels of the nozzle used, seeding the airflow with solid particles to perform PIV experiments was not an option. Instead liquid was injected in the air stream and a MATLAB routine was developed to identify the size of the seeding drops and filter out those that were larger than 3 x 3 pixels. The key to reducing combustion emissions such as nitrogen oxides (NOx) and carbon monoxide (CO) is fast and thorough mixing of fuel and air. The aim of multi-point lean direct injection (LDI) technique is to improve mixing and atomization by injecting fuel in small amounts through multiple injection ports. Multiple small injectors are used instead of a main injector introducing fuel and air streams in the combustion chamber. Various combustion studies reported in the literature showed that multi-point lean direct injection (LDI) nozzles had lower emissions compared to other ordinary nozzles. Besides these overall combustion performance studies there are no detailed investigations of the nozzle flow and the role of mixing and atomization in achieving the low emission performance. The objectives of this study were: (1) Characterize turbulence and spray fields; and (2) Investigate the effect of lateral jet interaction on spray quality and mixing. This work is an experimental investigation of the flow downstream of a multi-point LDI nozzle. The nozzle is a 3 x 3 square matrix of 9 small swirling air jets with fuel inject at the center of each jet. The design swirl number was 0.8 and the Reynolds number of the flow was 40 000. The experiments were conducted under non-burning conditions at atmospheric conditions. Particle image velocimetry (PIV) and Phase Doppler particle anemometry (PDPA) were used to map the velocity and spray properties. The investigation covered the region within the first 18 jet diameters downstream of the nozzle exit plane. The results showed that: (1) Lateral jet interaction slows the spreading rate of the jets and improves turbulence, thus mixing. The improved turbulence is due mostly to the opposing direction of the tangential component; (2) Increased spray number density and droplets relative velocity in the matrix favors coalescence; (3) Although smaller injectors achieve better atomization than ordinary nozzles, jet-jet interaction occurring when matrices of small jets are used offsets this gain in atomization quality; and (4) Results suggest that the emission reduction is due to improved mixing.

Available in PDF, EPUB and Kindle. Book excerpt: This book has been conceived to provide guidance on the theory and design of cyclone systems. Forthose new to the topic, a cyclone is, in its most basic form, a stationary mechanical device that utilizes centrifugal force to separate solid or liquid particles from a carrier gas. Gas enters near the top via a tangential or vaned inlet, which gives rise to an axially descending spiral of gas and a centrifugal force field that causes the incoming particles to concentrate along, and spiral down, the inner walls of the separator. The thus-segregated particulate phase is allowed to exit out an underflow pipe while the gas phase constricts, and - in most separators - reverses its axial direction of flow and exits out a separate overflow pipe. Cyclones are applied in both heavy and light industrial applications and may be designed as either classifiers or separators. Their applications are as plentiful as they are varied. Examples include their use in the separation or classification of powder coatings, plastic fines, sawdust, wood chips, sand, sintered/powdered meta!, plastic and meta! pellets, rock and mineral cmshings, carbon fines, grain products, pulverized coal, chalk, coal and coal ash, catalyst and petroleum coke fines, mist entrained off of various processing units and liquid components from scmbbing and drilling operations. They have even been applied to separate foam into its component gas and liquid phases in recent years.

Book excerpt: This successful textbook emphasizes the unified nature of all the disciplines of Fluid Mechanics as they emerge from the general principles of continuum mechanics. The different branches of Fluid Mechanics, always originating from simplifying assumptions, are developed according to the basic rule: from the general to the specific. The first part of the book contains a concise but readable introduction into kinematics and the formulation of the laws of mechanics and thermodynamics. The second part consists of the methodical application of these principles to technology. In addition, sections about thin-film flow and flow through porous media are included.

Available in PDF, EPUB and Kindle. Book excerpt: A new, thoroughly updated edition of a comprehensive overview of knowledge management (KM), covering theoretical foundations, the KM process, tools, and professions. The ability to manage knowledge has become increasingly important in today's knowledge economy. Knowledge is considered a valuable commodity, embedded in products and in the tacit knowledge of highly mobile individual employees. Knowledge management (KM) represents a deliberate and systematic approach to cultivating and sharing an organization's knowledge base. This textbook and professional reference offers a comprehensive overview of the field. Drawing on ideas, tools, and techniques from such disciplines as sociology, cognitive science, organizational behavior, and information science, it describes KM theory and practice at the individual, community, and organizational levels. Chapters cover such topics as tacit and explicit knowledge, theoretical modeling of KM, the KM cycle from knowledge capture to knowledge use, KM tools, KM assessment, and KM professionals. This third edition has been completely revised and updated to reflect advances in the dynamic and emerging field of KM. The specific changes include extended treatment of tacit knowledge; integration of such newer technologies as social media, visualization, mobile technologies, and crowdsourcing; a new chapter on knowledge continuity, with key criteria for identifying knowledge at risk; material on how to identify, document, validate, share, and implement lessons learned and best practices; the addition of new categories of KM jobs; and a new emphasis on the role of KM in innovation. Supplementary materials for instructors are available online.
