Download or read book SAE 2004 30 0038 An Experimental Validation of a Genetic Algorithm Coupled with a CFD Code for Combustion Chamber Design written by C.Y. Choi and published by . This book was released on 1999 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: An extensive evaluation was conducted to determine the feasibility of coupling the Genetic Algorithm (GA) optimization methodology with a combustion CFD code for production use. This methodology was applied to a Caterpillar research diesel engine and the optimal design produced by the GA was tested. Results showed that the optimal design performed as predicted at a target high-load operating condition by reducing both NOx and soot at equivalent brake specific fuel consumption (BSFC) when compared to a baseline Mexican-hat bowl and conventional nozzle configuration. Furthermore, the CFD code correctly predicted the magnitude of change in performance between optimal and baseline designs in 5 out of 6 emissions metrics over 3 operating modes. The optimal design did not outperform the baseline at all modes tested; however, results have validated both the predictive capability of the code as well as the feasibility of using a GA to produce viable engine designs that meet performance targets. The results suggest that to produce a design that is truly optimal over the entire speed-load range of a diesel engine, multi-modal optimizations should be performed in the future.

Download or read book Active Protective Coatings written by Anthony E. Hughes and published by Springer. This book was released on 2016-03-01 with total page 429 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers a broad range of materials science that has been brought to bear on providing solutions to the challenges of developing self-healing and protective coatings for a range of metals. The book has a strong emphasis on characterisation techniques, particularly new techniques that are beginning to be used in the coatings area. It features many contributions written by experts from various industrial sectors which examine the needs of the sectors and the state of the art. The development of self-healing and protective coatings has been an expanding field in recent years and applies a lot of new knowledge gained from other fields as well as other areas of materials science to the development of coatings. It has borrowed from fields such as the food and pharmaceutical industries who have used, polymer techniques, sol-gel science and colloidosome technology for a range encapsulation techniques. It has also borrowed from fields like hydrogen storage such as from the development of hierarchical and other materials based on organic templating as “nanocontainers” for the delivery of inhibitors. In materials science, recent developments in high throughput and other characterisation techniques, such as those available from synchrotrons, are being increasing used for novel characterisation – one only needs to look at the application of these techniques in self healing polymers to gauge wealth of new information that has been gained from these techniques. This work is largely driven by the need to replace environmental pollutants and hazardous chemicals that represent risk to humans such as chromate inhibitors which are still used in some applications.

Download or read book Advances in Concentrating Solar Thermal Research and Technology written by Manuel Blanco and published by Woodhead Publishing. This book was released on 2016-11-10 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: After decades of research and development, concentrating solar thermal (CST) power plants (also known as concentrating solar power (CSP) and as Solar Thermal Electricity or STE systems) are now starting to be widely commercialized. Indeed, the IEA predicts that by 2050, with sufficient support over ten percent of global electricity could be produced by concentrating solar thermal power plants. However, CSP plants are just but one of the many possible applications of CST systems. Advances in Concentrating Solar Thermal Research and Technology provides detailed information on the latest advances in CST systems research and technology. It promotes a deep understanding of the challenges the different CST technologies are confronted with, of the research that is taking place worldwide to address those challenges, and of the impact that the innovation that this research is fostering could have on the emergence of new CST components and concepts. It is anticipated that these developments will substantially increase the cost-competiveness of commercial CST solutions and reshape the technological landscape of both CST technologies and the CST industry. After an introductory chapter, the next three parts of the book focus on key CST plant components, from mirrors and receivers to thermal storage. The final two parts of the book address operation and control and innovative CST system concepts. - Contains authoritative reviews of CST research taking place around the world - Discusses the impact this research is fostering on the emergence of new CST components and concepts that will substantially increase the cost-competitiveness of CST power - Covers both major CST plant components and system-wide issues

Download or read book Atmospheric Aerosols written by Olivier Boucher and published by Springer. This book was released on 2015-05-18 with total page 322 pages. Available in PDF, EPUB and Kindle. 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.
