Book excerpt: In an opposed-jet diffusion flame experiment, under certain conditions, after the extinction of the diffusion flame, an edge flame can be obtained. It was reported recently in a numerical and an experimental work and is responsible for an interesting transition between two distinct burning flames (multiple solutions). Motivated by our previous numerical results, obtained with simplified kinetics and some recently reported experimental data, we performed direct numerical simulations of this transition to investigate the underlying physical mechanisms. The appearance of an edge flame after the extinction of the diffusion flame, the hysteresis reported in the experiments, and the existence of multiple vigorously burning flames at identical conditions are all captured by our simulations. Our numerical results show that, in the absence of an inert coflow curtain, when the diffusion flame disk is extinguished, an edge flame forms and propagates in the mixing layer. After the formation of this edge flame, even when the applied strain rate is reduced to the initial subcritical value, the diffusion flame disk does not reappear, because the local fluid velocity still exceeds the propagation speed of the edge flame. This hysteresis has significant implications in the common submodel that utilizes the strain rate as a parameter to determine local reignition in flamelet models; it indicates that a subcritical strain rate is not a sufficient condition for the reignition of a diffusion flame. Further investigation of this phenomenon is clearly needed to refine submodels of local extinction and reignition in the flamelet models for turbulent diffusion flames. The opposed-jet configuration provides a convenient platform to analyze edge flames which are stabilized aerodynamically in a two-dimensional geometry, thus making matching two-dimensional direct numerical simulations effective.

This book was released on 2020-08-19 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines a broad range of advances in hydrogen energy and alternative fuel developments and their role in the energy transition. The respective contributions were presented at the International Symposium on Sustainable Hydrogen, held in Algiers, Algeria on November 27-28, 2019. The transition from non-renewable polluting energy to sustainable green energy requires not only new energy sources but also new storage techniques and smart energy management. This situation has sparked renewed interest in hydrogen and alternative fuels, as they could help meet these needs. Indeed, hydrogen can not only be used as a clean energy vector or as an alternative fuel, but also as a storage medium or as an intermediary that enables improved energy management. This text offers a valuable reference guide for those working in the professional energy sector, as well as for students and instructors in academia who want to learn about the state of the art and future directions in the fields of hydrogen energy, alternative fuels and sustainable energy development.
