Scramjet Combustion (eBook)

Scramjet Combustion explores the development of a high-speed scramjet engine operating in the supersonic/hypersonic range for various air and space transport applications. The book explains the basic structure, components, working cycle, and the relevant governing equations in a clear manner that speaks to both advanced and more novice audiences. Particular attention is paid to efficient air-fuel combustion, looking at both the underlying fundamentals of combustion as well strategies for obtaining optimum combustion efficiency. Methods for reaching the chemically correct air-fuel ratio, subsequent flame, and combustion stabilization as air enters at supersonic speed are also outlined. Further, it includes the continuous on-going efforts, innovations, and advances with respect to the design modification of scramjet combustors, as well as different strategies of fuel injections for obtaining augmented performance while highlighting the current and future challenges.

• Outlines the fundamentals of scramjet engines including their basic structure and components, working cycle, governing equations, and combustion fundamentals affecting the combustion and mixing processes
• Presents new design modifications of scramjet combustors and different fuel injection strategies including combined fuel injection approaches
• Discusses core topics such as chemical kinetics in supersonic flow, fuel-air mixing methods, strategies for combating combustion difficulties, and subsequent flame and combustion stabilization that can be applied to scramjets
• Describes the pedagogy for computational approaches in simulating supersonic flows

Dr. Gautam Choubey is presently working as Assistant Professor in the Department of Mechanical and Aerospace Engineering at the Institute of Infrastructure Technology Research and Management (IITRAM), Ahmedabad, India. He holds a PhD in the field of supersonic combustion and an M. Tech in thermal engineering from the National Institute of Technology Silchar, Assam, India. For the past 8 years, his research has focused on computational fluid dynamics modelling of supersonic compressible flow. Dr. Choubey has authored more than 30 publications in reputed SCI journals. His research interest mainly includes scramjet combustion, supersonic combustion, turbulence modelling in high-speed flows, and shock-boundary layer interaction. He also figured among top 2% researchers and scientists of the world in a report published by Stanford University (United States) and Elsevier BV (Netherlands) for the year 2020.
