 This revised and updated sixth edition continues to provide the most accessible and readable approach to the study of all the vital topics and issues associated with gas dynamic processes.

With a strong emphasis on the basic concepts and problem-solving skills, this text is suitable for a course on Gas Dynamics/Compressible Flows/High-speed Aerodynamics at both undergraduate and postgraduate levels in aerospace engineering, mechanical engineering, chemical engineering and applied physics.

In this edition, detailed analytical derivations of the shock polar relation, expressions for the pressure and density ratio across an expansion fan, the relation between the Mach numbers of incident and reflected shocks and the mathematical steps in arriving at the q−b−M relation of oblique shock are incorporated. Besides, the book includes several new solved examples on important analytical relations. New problems have been added in a number of chapters to help students practice applications of the theory studied.

Some of the Distinguishing Features of the Book 
• Concise coverage of the thermodynamic concepts to serve as a revision of the background material.
• Logical and systematic treatment of fundamental aspects of gas dynamics, waves in the supersonic regime and gas dynamic processes.
• In-depth presentation of potential equations for compressible flows, similarity rule and two-dimensional compressible flows.
• Introduction to measurements in compressible flows and optical flow visualization techniques.
• Introduction to rarefied gas dynamics and high-temperature gas dynamics.
• Solutions Manual for instructors containing the complete worked-out solutions to chapter-end problems.
• Computer program to calculate the coordinates of contoured nozzle in C-language.

About the author (2017)

 ETHIRAJAN RATHAKRISHNAN, Ph.D., is Professor of Aerospace Engineering at the Indian Institute of Technology Kanpur. He is well known internationally for his research in the area of high-speed jets. The limit for the passive control of jets, called Rathakrishnan Limit, is his contribution to the field of jet research. The concept of breathing blunt nose (BBN), which reduces the positive pressure at the nose and increases the low pressure at the base simultaneously, is his contribution to drag reduction at hypersonic speeds. He has published a large number of research articles in many reputed international journals. He is a Fellow of many professional societies, including the Royal Aeronautical Society.

Professor Rathakrishnan serves as the Editor-in-Chief of the International Review of Aerospace Engineering (IREASE) and International Review of Mechanical Engineering (IREME) journals. He has authored two books, Fundamentals of Engineering Thermodynamics, 2nd ed. and Fluid Mechanics: An Introduction, 3rd ed., published by PHI Learning, Delhi. Besides, he has also authored eight other books, namely, Gas Tables; Instrumentation, Measurements, and Experiments in Fluids; Theory of Compressible Flows; Gas Dynamics Work Book; Applied Gas Dynamics; Elements of Heat Transfer; Theoretical Aerodynamics; High Enthalpy Gas Dynamics.
