Download or read book Nonlinear Hyperbolic Waves in Multi-Dimensions written by Phoolan Prasad and published by . This book was released on 1999-05 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The propagation of curved, nonlinear wavefronts and shock fronts is a very complex phenomena. This book provides a self-contained account an d gradual development of mathematical methods for studying successive positions of these fronts. It includes an introduction to shock fronts, derives the ray theory for a nonlinear wavefront, discusses kink phe nomena, develops a new theory for plane and curved shock propagation, and contains Huygens' method of wavefronts construction and an extensi on of Fermat's principle. The book also has approximate equations to d iscuss stability of steady transonic flows. The author includes a num ber of examples of the theory to converging wavefronts in gasdynamics and demonstrates numerical computations. All of the results presented are new and were developed by the author and his research group.
