Hypersonic Shock Wave Turbulent Boundary Layers

This book provides an essential overview of experimental knowledge of hypersonic turbulent boundary layers, and summarises the state-of-the-art of Direct Numerical (DNS) and Large Eddy Simulation (LES) of hypersonic turbulent boundary layers. It also provides a roadmap for both future experiments and DNS and LES simulations. The book comprises eight chapters plus appendices. Chapter 1 presents an introduction to hypersonic flight with emphasis on both historical and recent civilian and military vehicles. The need for understanding the flow physics of hypersonic flight, in particular the turbulent boundary layers on the vehicle surface, is emphasized with historical examples of the unintended consequences of inadequate knowledge of the flow physics. Chapter 2 presents the mathematical theory of hypersonic turbulent boundary layers with a detailed discussion of the state-of-the-art methods of numerical simulation through Direct Numerical Simulation (DNS) and Large Eddy Simulation (LES). Chapter 3 examines the structure of equilibrium turbulent boundary layers (i.e., in the absence of strong pressure gradients due to shock wave) as deduced from experiment and theory. Chapters 4 and 5 present the state-of-the-art of experimental investigations of equilibrium hypersonic turbulent boundary layers (Chapter 4) and shock wave turbulent boundary layer interaction (Chapter 5). These two chapters constitute the complete experimental dataset for validation of DNS and LES modelling of hypersonic turbulent boundary layers. Chapters 6 and 7 summarize the state-of-the-art modelling of hypersonic turbulent boundary layers using DNS and LES. Chapter 8 details the future needs for modelling turbulent boundary layers and provides a roadmap for both experimental and modelling research.
