Turbulent Shear Layers in Supersonic Flow is a technical book that focuses on the analysis of turbulent compressible flows, which are crucial for the design and operation of high-speed vehicles. These flows occur, for example, in the external flow over the surfaces of supersonic aircraft and in the internal flow through their engines. Understanding turbulent shear layers is essential for predicting aerodynamic lift, drag, thrust, and maneuverability of high-speed vehicles. The book provides a comprehensive introduction to the topic and establishes a solid foundation for future research in this area. It utilizes available experimental work and results from numerical simulations to develop and illustrate a physical understanding of turbulent compressible flows.
