Compressible fluid dynamics and shock waves This book offers comprehensive coverage of compressible flow phenomena and their applications and is intended for undergraduate graduate students practicing professionals and researchers interested in the topic. Thanks to the clear explanations provided of a wide range of basic principles the equations and formulas presented here can be understood with only a basic grasp of mathematics. The book particularly focuses on shock waves offering a unique approach to the derivation of shock wave relations from conservation relations in fluids together with a contact surface slip line or surface; in addition the thrust of a rocket engine and that of an air breathing engine are also formulated. Furthermore the book covers important fundamentals of various aspects of physical fluid dynamics and engineering including one dimensional unsteady flows and two dimensional flows in which oblique shock waves and Prandtl Meyer expansion can be observed. Propagation of pressure waves Motions of gas particles related to thermodynamics Basic equations for flow Discontinuity Quasi one dimensional flows System with source terms Two dimensional flows Unsteady one dimensional flows Riemann problem Method of characteristics Generation and applications of compressible flows Shock like phenomena.
