Explosion Dynamics Structured and comprehensive introductory guide to understanding and applying explosion dynamics concepts Explosion Dynamics thoroughly explores the physical phenomena of explosions and enables readers to understand controlling variables that govern temperature, pressure, and rate of increase in pressure respectively, while also providing a mathematical framework for characterizing and applying key concepts. To promote seamless reader comprehension, this comprehensive textbook provides working examples, case studies, and assignments for self-study, as well as additional material such as property data for common gases and dusts, which supports the examples presented throughout the text. Written by two highly qualified authors, topics covered in Explosion Dynamics include: Similitude theory, similarity solutions, nonlinear systems of differential equations, gas dynamics, and chemical kinetics How a flammable mixture of gas or vapor or a suspension of powder, dust particles, or droplets forms in the industrial processing of hazardous materials Range of temperature, pressure, and concentration in which a flame can ignite and propagate How the “rate-of-pressure-rise” affects the overall explosion hazard and the viability of various explosion protection measures Providing a structured and comprehensive approach to the subject, Explosion Dynamics is an indispensable textbook that allows chemistry and engineering students, along with professional engineers and professionals in the chemical and food industries, to understand the fundamental mathematics and physics involved in explosions and develop appropriate protection and prevention measures.

Dust Explosion Dynamics focuses on the combustion science that governs the behavior of the three primary hazards of combustible dust: dust explosions, flash fires, and smoldering. It explores the use of fundamental principles to evaluate the magnitude of combustible dust hazards in a variety of settings. Models are developed to describe dust combustion phenomena using the principles of thermodynamics, transport phenomena, and chemical kinetics. Simple, tractable models are described first and compared with experimental data, followed by more sophisticated models to help with future challenges. Dr. Ogle introduces the reader to just enough combustion science so that they may read, interpret, and use the scientific literature published on combustible dusts. This introductory text is intended to be a practical guide to the application of combustible dust models, suitable for both students and experienced engineers. It will help you to describe the dynamics of explosions and fires involving dust and evaluate their consequences which in turn will help you prevent damage to property, injury and loss of life from combustible dust accidents. - Demonstrates how the fundamental principles of combustion science can be applied to understand the ignition, propagation, and extinction of dust explosions - Explores fundamental concepts through model-building and comparisons with empirical data - Provides detailed examples to give a thorough insight into the hazards of combustible dust as well as an introduction to relevant scientific literature

This sequel to Randall Collins' world-influential micro-sociology of violence introduces the question of time-dynamics: what determines how long conflict lasts and how much damage it does. Inequality and hostility are not enough to explain when and where violence breaks out. Time-dynamics are the time-bubbles when people are most nationalistic; the hours after a protest starts when violence is most likely to happen. Ranging from the three months of nationalism and hysteria after 9/11 to the assault on the Capitol in 2021, Randall Collins shows what makes some protests more violent than others and why some revolutions are swift and non-violent tipping-points while others devolve into lengthy civil wars. Winning or losing are emotional processes, continuing in the era of computerized war, while high-tech spawns terrorist tactics of hiding in the civilian population and using cheap features of the Internet as substitutes for military organization. Nevertheless, Explosive Conflict offers some optimistic discoveries on clues to mass rampages and heading off police atrocities, with practical lessons from time-dynamics of violence.

This book deals with explosive instabilities in mechanics, deriving a solution to a system of PDEs that arise in practical situations. It begins with a relatively simple account of blow-up in systems of interaction-diffusion equations. Among the topics presented are: classical fluid equations, catastrophic behavior in nonlinear fluid theories, blow-up in Volterra equations, and rapid energy growth in parallel flows.
