This book was released on 2011 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spray nozzles and atomizers have several applications in many forms of industry such as aerospace, automotive, combustion, pharmaceutical, and spray coating industries. These nozzles vary in design and performance depending on the application they are used in. Nevertheless, the primary objective for all atomizers is to disperse liquids in a controlled and uniformed manner while minimizing the amount of energy needed in the breakup process to achieve high quality atomization. Air-assist and air-blast atomizers are fuel injector nozzles commonly used in gas turbine engines in the aerospace, and power generation industries. The flow in these atomizers is considered to be two-phase flow since a portion of air taken from the compressor is also used to assist in the breakup of the fuel inside the combustion chamber. These nozzles play a critical role in determining the efficiency of gas turbine engines as their ability to disperse liquid fuel into fine droplets allows for better mixture and evaporation rates; therefore, improving engine performance, reducing emissions, and maximizing fuel efficiency. The objective of this study is to experimentally analyze two gas turbine fuel injector nozzles. The first nozzle is a standard hollow cone nozzle currently used in gas turbine engines, whereas the other is a hollow elliptical nozzle designed to offer greater control over fuel distribution as well as improve overall atomization. The nozzles are investigated under varying gas to liquid ratios (GLR) where key spray parameters such as droplet diameter, velocity, volume flux, as well as spray angle are measured to characterize the nozzles using methods such as Shadowgraph, Optical Patternation, Phase Doppler Particle Analyzer (PDPA), and Particle Image Velocimetry (PIV).

This book was released on 2013-11-11 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a great deal of interest in extending nondestructive technologies beyond the location and identification of cracks and voids. Specifically there is growing interest in the application of nondestructive evaluation (NOEl to the measurement of physical and mechanical properties of materials. The measurement of materials properties is often referred to as materials characterization; thus nondestructive techniques applied to characterization become nondestructive characterization (NDCl. There are a number of meetings, proceedings and journals focused upon nondestructive technologies and the detection and identification of cracks and voids. However, the series of symposia, of which these proceedings represent the fourth, are the only meetings uniquely focused upon nondestructive characterization. Moreover, these symposia are especially concerned with stimulating communication between the materials, mechanical and manufacturing engineer and the NDE technology oriented engineer and scientist. These symposia recognize that it is the welding of these areas of expertise that is necessary for practical development and application of NDC technology to measurements of components for in service life time and sensor technology for intelligent processing of materials. These proceedings are from the fourth international symposia and are edited by c.o. Ruud, J. F. Bussiere and R.E. Green, Jr. . The dates, places, etc of the symposia held to date area as follows: Symposia on Nondestructive Methods for TITLE: Material Property Determination DATES: April 6-8, 1983 PLACE: Hershey, PA, USA CHAIRPERSONS: C.O.

Book Synopsis Automotive Painting Technology by : Kimio Toda
Download or read book Automotive Painting Technology written by Kimio Toda and published by Springer Science & Business Media. This book was released on 2012-12-21 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers unique and valuable contributions to the field. It offers breadth and inclusiveness. Most existing works on automotive painting cover only a single aspect of this complex topic, such as the chemistry of paint or paint booth technology. Monozukuri and Hitozukuri are Japanese terms that can be translated as “making things” and “developing people” but their implications in Japanese are richer and more complex than this minimal translation would indicate. The Monozukuri-Hitozukuri perspective is drawn from essential principles on which the Toyota approach to problem-solving and continuous improvement is based. From this perspective, neither painting technology R&D nor painting technology use in manufacturing can be done successfully without integrating technological and human concerns involved with making and learning in the broadest sense, as the hyphen is meant to indicate. The editors provide case studies and examples -- drawn from Mr. Toda’s 33 years of experience with automotive painting at Toyota and from Dr. Saito’s 18 years experience with IR4TD, the research-for-development group he leads at the University of Kentucky -- that give details on how these two principles can be integrated for successful problem-solving and innovation in industry, in university R&D, and in the collaboration between the two. The book will bring readers up to date on progress in the field over the last decade to provide a basis for and to indicate fruitful directions in future R&D and technology innovation for automotive painting.
