Description
Gas turbine engines and systems are designed to convert the energy of a fuel into some form of useful power, such as mechanical shaft power, electrical power, or the high-speed thrust of a jet. Research and development designed to perfect efficient cooling in gas turbines require fundamental and applied investigations of heat transfer. Containing invited contributions from some of the most prominent specialists working in this field today, this unique title reflects current active research and covers a broad spectrum of heat transfer phenomena in gas turbines. All of the chapters follow a unified outline and presentation to aid accessibility and the book provides invaluable information for both graduate researchers and R&D engineers in industry and consultancy.
