Book excerpt: Over Australia's 2019-20 Black Summer bushfire season, scientists estimate that more than three billion native animals were killed or displaced. Many species - koalas, the regent honeyeater, glossy black cockatoo, the platypus - are inching towards extinction at the hands of mega-blazes and the changing climate behind them. In Flames of Extinction, award-winning science writer John Pickrell investigates the effects of the 2019-2020 bushfires on Australian wildlife and ecosystems. Journeying across the firegrounds, Pickrell explores the stories of creatures that escaped the flames, the wildlife workers who rescued them, and the conservationists, land managers, Aboriginal rangers, ecologists and firefighters on the front line of the climate catastrophe. He also reveals the radical new conservation methods being trialled to save as many species as possible from the very precipice of extinction.

This book was released on 2017-07-18 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents pioneering experimental and numerical studies on three aspects of the combustion characteristics of lean premixed syngas/air flames, namely the laminar flame speed, extinction limit and flammability limit. It illustrates a new extinction exponent concept, which enriches the combustion theory. Above all, the book provides the following: a) a series of carefully measured data and theoretical analyses to reveal the intrinsic mechanisms of the fuel composition effect on the propagation and extinction of lean syngas/air flames; b) a mixing model and correlation to predict the laminar flame speed of multi-component syngas fuels, intended for engineering computations; c) a new “extinction exponent” concept to describe the critical effects of chemical kinetics on the extinction of lean premixed syngas/air flames; and d) the effects and mechanism of the dilution of incombustible components on lean premixed syngas/air flames and the preferential importance among the thermal, chemical and diffusion effects.

Available in PDF, EPUB and Kindle. Book excerpt: Several researchers have examined the concept of flame stability and there has been little agreement regarding the reasons governing this phenomenon. The experiments described within were devised to establish the dominating stabilization mechanism in lifted flames. Specifically, the flame base of lifted methane-jet diffusion flames were examined through the use of various combinations of synchronized laser-based techniques involving particle image velocimetry (PIV), planar laser-induced fluorescence (PLIF), and Rayleigh scattering. Results indicate the presence of a structure termed a flame. Results involving the gradient in the Rayleigh signal across the flame base, in addition to two-shot CH-PLIF interpretations support the leading-edge flame as a primary stabilization mechanism. The extent of premixing upstream of the flame base has been a major source of disagreement in the past. The simultaneous Rayleigh and CH-PLIF images indicate the base of the lifted flame lies in a region that is within the flammability limits of methane burning in air. Furthermore, the average velocity at the stabilization point is 1.18 m/s (as determined from the simultaneous CH-PLIF and PIV investigation); this value is comparable to three times the laminar burning velocity of methane (~ 3S), thereby supporting previous numerical triple flame simulations. Results from the joint two-shot CH-PLIF and PIV technique show that the flame base velocity is independent of the flow conditions when the flame is stationary during the time separation of the CH-PLIF pulses. Specifically, flames with Re flow conditions. Finally, regions of local extinction -- as indicated by openings in the CH profiles -- were examined. Results from four experiments (simultaneous CH-PLIF and PIV, simultaneous CH-PLIF and OH-PLIF, simultaneous CH-PLIF and Rayleigh scattering, and simultaneous two-shot CH-PLIF and PIV) provide complementary information regarding the role of large-scale fuel vortices in initiat.

Book excerpt: Extensively using experimental and numerical illustrations, CombustionPhenomena: Selected Mechanisms of Flame Formation, Propagation, and Extinction provides a comprehensive survey of the fundamental processes of flame formation, propagation, and extinction. Taking you through the stages of combustion, leading experts visually display, mathematically explain, and clearly theorize on important physical topics of combustion. After a historical introduction to the field, they discuss combustion chemistry, flammability limits, and spark ignition. They also study counterflow twin-flame configuration, flame in a vortex core, the propagation characteristics of edge flames, instabilities, and tulip flames. In addition, the book describes flame extinction in narrow channels, global quenching of premixed flames by turbulence, counterflow premixed flame extinction limits, the interaction of flames with fluids in rotating vessels, and turbulent flames. The final chapter explores diffusion flames as well as combustion in spark- and compression-ignition engines. It also examines the transition from deflagration to detonation, along with the detonation wave structure. With downloadable resources of images that beautifully illustrate a range of combustion phenomena, this book facilitates a practical understanding of the processes occurring in the conception, spread, and extinguishment of a flame. It will help you on your way to finding solutions to real issues encountered in transportation, power generation, industrial processes, chemical engineering, and fire and explosion hazards.

Available in PDF, EPUB and Kindle. Book excerpt: A Gallery of Combustion and Fire is the first book to provide a graphical perspective of the extremely visual phenomenon of combustion in full color. It is designed primarily to be used in parallel with, and supplement existing combustion textbooks that are usually in black and white, making it a challenge to visualize such a graphic phenomenon. Each image includes a description of how it was generated, which is detailed enough for the expert but simple enough for the novice. Processes range from small scale academic flames up to full scale industrial flames under a wide range of conditions such as low and normal gravity, atmospheric to high pressures, actual and simulated flames, and controlled and uncontrolled flames. Containing over 500 color images, with over 230 contributors from over 75 organizations, this volume is a valuable asset for experts and novices alike.

Book excerpt: Finally, the effects of kinetic and transport coupling on ignition and flame propagation are investigated by using dimethyl ether (DME) blended methane/air mixtures. It is shown that the addition of a small amount of DME to methane leads to a significant decrease in the ignition time, while the flame speed of DME/CH4/air mixture is only linearly proportional to the DME fraction.
