Applied Gas Dynamics

Applied Gas Dynamics introduces the science and technology of gas dynamics, beginning with the definition of the subject (Gas Dynamics is a science of fluid flow where both density and temperature changes associated with the flow are significant) and introduces the three essential process of this science, namely, the isentropic process, shock and expansion process, and Fanno and Rayleigh flows, in such a manner that any beginner can follow the subject comfortably. This text is developed covering both theoretical and application aspects of Gas Dynamics. The coverage begins with the basic features of the flow physics and moves to advanced topics of devices involving internal and external flows such as thrust producing rocket nozzles and lift generating aerofoils. The physics of flows with significant changes in both density and temperature are discussed highlighting their theory and application throughout the book. At every stage appropriate practical examples are given to emphasizing the application of the theory, as are exercise problems with answers at the end of every chapter. Isentropic, normal shock, oblique shock and Fanno and Rayleigh Tables are given in the appendix.

Ethirajan Rathakrishnan is a Professor of Aerospace Engineering at the Indian Institute of Technology, Kanpur, where he is in charge of the high speed aerodynamics laboratory. Rathakrishnan's research interests are experimental and theoretical gas dynamics and rarefied flows, as well as applied gas dynamics in high speed jets, sudden expansion problems, aeroacoustics, and active and passive control of jets and base flows. He has led numerous research projects with the Indian Space Research Organization (ISRO), Defense Research and Development Organisation (DRDO), National Aerospace Laboratory (NAL), Hindustan Aeronautics Limited (HAL) and IIT Kanpur. He has been a visiting professor at Clarkson University, Florida State University, Hyperschall Technologie Gottingen, the International Centre for Theoretical Physics, Trieste, Italy, and the University of Tokyo. Honors include the Excellence in Aerospace Education Award from the President of India and Best Teacher Award by the Uttar Pradesh Chapter of Publishers. Rathakrishnan is also an active conference organizer and keynote speaker. He holds a BSc in Mathematics from Madras University, DMIT in Aerodynamics, Propulsion, and Aircraft Structures from MIT Madras, an M Tech in Aerodynamics from IIT Madras, and a PhD in Gas Dynamics: Rarefied and Continuum Regimes from IIT Madras.
