"Study of Effusion Cooling in Combustion Chamber of a Gas Turbine" provides an in-depth analysis of advanced cooling techniques critical for the performance and durability of modern gas turbines. This book focuses on effusion cooling, a method that involves the injection of a cooling fluid through numerous small holes to create a protective layer over the combustion chamber surfaces. It explores the principles behind effusion cooling, its advantages over traditional cooling methods, and its impact on reducing thermal stresses and extending the lifespan of turbine components. Through comprehensive simulations, experimental data, and real-world applications, this book offers valuable insights into optimizing gas turbine operation, improving fuel efficiency, and reducing emissions. It is an essential resource for engineers and researchers seeking to enhance the reliability and performance of gas turbine technology in high-temperature environments.

Heat transfer enhancement plays an important role in areas, such as electronics cooling, compact heat exchangers, power plants, gas turbine airfoil cooling, etc. Modern high-performance gas turbine engines operate at high entry gas temperature, well above the allowable metal temperature. Therefore, highly efficient cooling technologies (film cooling, impingement cooling, and internal cooling) are required for vanes and blades of advanced gas turbines. In this book, the authors are shows the effect of incorporating ribs in the straight channels with variable aspect ratio. The effect of Reynolds number on fluid flow and heat transfer is also investigated.
