Due to the increase in computational power and new discoveries in propagation phenomena for linear and nonlinear waves, the area of computational wave propagation has become more significant in recent years. Exploring the latest developments in the field, Effective Computational Methods for Wave Propagation presents several modern, valuable computational methods used to describe wave propagation phenomena in selected areas of physics and technology.Featuring contributions from internationally known experts, the book is divided into four parts. It begins with the simulation of nonlinear dispersive waves from nonlinear optics and the theory and numerical analysis of Boussinesq systems. The next section focuses on computational approaches, including a finite element method and parabolic equation techniques, for mathematical models of underwater sound propagation and scattering. The book then offers a comprehensive introduction to modern numerical methods for time-dependent elastic wave propagation. The final part supplies an overview of high-order, low diffusion numerical methods for complex, compressible flows of aerodynamics. Concentrating on physics and technology, this volume provides the necessary computational methods to effectively tackle the sources of problems that involve some type of wave motion.

Modeling and Simulation of Multiphase and Reactive Flows: From Fundamentals to Engineering Applications offers integrated coverage of state-of-the-art advancements in the study of computational fluid dynamics. The book accompanies readers on a pedagogically progressive journey that exposes them first to the fundamental physics of multicomponent flows and then moves on to more advanced topics in a number of target applications of current interest, with particular emphasis on aerospace, automotive, thermal, and nuclear engineering. A wide spectrum of flows including bubbly flows, liquid atomization, cavitation, chemically reactive flows, spray combustion, hypersonic flows, and detonation motion are discussed.Further cognizance of how to control and manipulate these phenomena is enabled by leveraging powerful technologies for numerical modeling and simulation techniques, with worked-out computational exercises and sample case studies also being featured to encourage practical endeavors to promisingly enhance the performance of many propulsion and energy systems.Covers fluid dynamics and its modeling, along with in-depth to ground understanding of key characteristics and behaviors of multi-component flowsFosters a case-based learning approach to survey all relevant types of fluid flows and their engineering applications, investigating common issues and remedies through helpful computational methodsIncludes a MATLAB toolbox that visualizes high-fidelity simulation results
