The book "Gas Turbine Heat Transfer and Cooling Technology" by Je-Chin Han, Sandip Dutta, and Srinath Ekkad provides a comprehensive overview of the heat transfer and cooling technologies used in gas turbines. The authors discuss the fundamental need for turbine blade cooling, driven by the increasing turbine inlet temperatures (TIT) to enhance thermal efficiency and power output. They cover various cooling techniques, including internal cooling, film cooling, and impingement cooling, and their impact on turbine performance and durability. The book is structured into several chapters, each focusing on different aspects of gas turbine heat transfer and cooling. Chapter 1 introduces the need for turbine blade cooling, detailing recent developments in aircraft engines and land-based gas turbines. Chapter 2 delves into turbine heat transfer, discussing the challenges and experimental methods for measuring heat flux and mass transfer. Chapter 3 focuses on film cooling, explaining its principles and the effects of various parameters such as coolant-to-mainstream ratios and hole geometry. Chapter 4 explores internal cooling, including jet impingement, rib-turbulated, and pin-fin cooling techniques. Chapter 5 examines the effects of rotation on cooling, while Chapter 6 covers experimental methods for heat transfer and cooling measurements. Chapter 7 discusses numerical modeling techniques, and Chapter 8 provides final remarks and suggestions for future research. The authors emphasize the importance of advanced cooling technologies and modern experimental and computational methods to address the complex heat transfer and cooling challenges in gas turbines. They also highlight the need for continued research and development to improve the performance and durability of gas turbine components.The book "Gas Turbine Heat Transfer and Cooling Technology" by Je-Chin Han, Sandip Dutta, and Srinath Ekkad provides a comprehensive overview of the heat transfer and cooling technologies used in gas turbines.
