This book was released on 2019-07-20 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: The following study is a compilation on the research and development in the field of horizontal axis wind turbines. It is known that in the wind energy industry, the horizontal axis wind turbines take lead over all other types. They are applicable on the domestic level too but this work focuses on the large scale machines. A driving factor is that they are a source of green energy. The other reason is that the horizontal axis wind turbines are more efficient than the vertical axis wind turbines. They have a number of mechanical components but the ones emphasized in this study are primarily the aerodynamics related ones. To confine, rotor has been the major area of study and research. The vital part is blade, so, the work is majorly around performance aspects of the blade. An effort is made to explore the possibilities of improvement in blade design variables. A cursory investigation is also done on another related structural component, tower, which affects the performance of rotor. A brief review of the horizontal axis wind turbine life cycle is also included in order to mark the environmental implications of it as a product. Analyses of the researchers have been studied and many important and recent findings have been highlighted. Modern techniques which are used for the enhancement of design variables, are investigated and recent works on correction factors for the governing equations have been discussed.

Analyses of the researchers have been studied and many important and recent findings have been highlighted. Modern techniques which are used for the enhancement of design variables, are investigated and recent works on correction factors for the governing equations have been discussed. The aim of this study is to review the current research on the HAWTs. The purpose is to explore the possibilities toward the improvement of design variables relating to the aerodynamic performance. To mention explicitly, the study focuses on the improvement in the design aspects of rotor which predominantly depends on the blade. The intent is to investigate the pros and cons of altering various parameters of the blade; aiming at the improved performance, keeping in view the material, manufacturing and the environmental aspects of the stated WTs as a product.The work starts with the overview of the wind energy capacity of various countries, to have surface knowledge of the importance of the technology. The study covers the basic features of HAWTs as well as VAWTs, that is, the other wind energy technology. A basic review is had on the various relevant aspects of the wind farm which directly affect the performance of HAWTs. To investigate HAWT as a product; its environmental impacts have been estimated in order to justify the technology. Starting from the aerodynamic efficiency limit, that is, Betz's limit, various governing equations previously derived have been highlighted and along with that the correction factors have been discussed which refine the analyses based on the applied theories.An investigation on the performance of the blade, as the main part of the rotor, has been done. Correlation of various design variables has been observed. Some findings relevant to the performance improvement have been stated. Novel approaches like using VAWTs as the supporting machines for HAWTs and having multi rotor WTs have been studied to see if they are viable at some scale of power generation. There is a limit to the optimization of the blade that the researchers can do. So, according to applications, the workability of the stated novel approaches is studied as well as recommended for future research.

Appearing annually in Choice's January issue, this prestigious list of publications reflects the best in scholarly titles and attracts extraordinary attention from the academic library community. The authoritative reference on wind energy, now fully revised and updated to include offshore wind power A decade on from its first release, the Wind Energy Handbook, Second Edition, reflects the advances in technology underpinning the continued expansion of the global wind power sector. Harnessing their collective industrial and academic expertise, the authors provide a comprehensive introduction to wind turbine design and wind farm planning for onshore and offshore wind-powered electricity generation. The major change since the first edition is the addition of a new chapter on offshore wind turbines and offshore wind farm development. Opening with a survey of the present state of offshore wind farm development, the chapter goes on to consider resource assessment and array losses. Then wave loading on support structures is examined in depth, including wind and wave load combinations and descriptions of applicable wave theories. After sections covering optimum machine size and offshore turbine reliability, the different types of support structure deployed to date are described in turn, with emphasis on monopiles, including fatigue analysis in the frequency domain.

Available in PDF, EPUB and Kindle. Book excerpt: Rotating machinery or turbomachinery is a machine with a rotating component that transfers energy to a fluid or vice versa. Rotating machines are one of the most widely used machines. They are used in everyday life, at least once a day. We find a turbomachine (fan) in a hair dryer and in a computer. We find a turbomachine (pump) in a refrigerator. Other commonly used household machines are clothes washers and dish washers. These machines need to drain the dirty water and replace with clean water. To do so an important component of these machines is a pump that is used to remove the dirty water. A water pump (hydrodynamic pump) is also essential to our car?s operation by maintaining an optimum operating temperature of the engine. The pump ensures that the coolant keeps circulating through the engine block, hoses and radiator, and maintains an optimum operating temperature. Turbomachines are also key machines used in power generation, fluid transportation, the processing industry and energy conversion. This book presents recent developments in improving the aero-thermal performance and the efficiencies of rotating machines.

Download or read book Wind Turbine Aerodynamic Performance Calculation written by Tongguang Wang and published by Springer Nature. This book was released on 2023-12-15 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with horizontal-axis wind turbine aerodynamic performance prediction methods. It focuses on the traditional and newly-developed methods for the wind turbine aerodynamic performance calculation. The fundamental theories of fluid mechanics essential for understanding the other parts of this book are firstly introduced in Part I, followed by the blade element momentum theory in Part II, with special attentions to a systematic review of various correction models. Part III is mainly about the prescribed and free vortex wake methods, while the state-of-art computational fluid dynamics (CFD) methods are detailed in Part IV. Part III thoroughly describes the prescribed and free vortex wake methods which are still of great importance towards realistic investigation of wind turbine performance. Despite the highly computational cost, the CFD methods in Part IV have received increasing interest from the academic community since they provide more detailed information about the flow field around the wind turbine. This has shed a light in combination with the correction models introduced in Part II on more advanced research for wind turbine. This book is intended for researchers and students interested in aerodynamics of wind turbine and is particularly suitable for practicing engineers in wind energy. Readers can gain a comprehensive understanding in both classical and up-to-date methods for the study of wind turbine aerodynamics. The authors hope that this book can promote the research and development of wind turbines.
