Download or read book Flame Spread in Confined Spaces written by Yanjun Li and published by . This book was released on 2021 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fire behaviors can be significantly different in confined spaces compared with in an open space. Evidence has shown that when subjected to flow confinement, flame can be stronger and spread faster over solid materials. This raises fire safety concern in confined spaces both on earth (e.g., tunnels, building structures) and in space (e.g., space vehicle). To address this concern and to advance understanding of the fire dynamics in confined environments, concurrent-flow flame spread over solid combustibles are investigated in microgravity aboard the International Space Station (ISS). Two types of solid fuel, thin cotton blend fabric (SIABL) and 1 mm thick PMMA slabs are burned in a small flow duct. To effectively reduce the space for flame growth, flow baffles are mounted parallel to the sample. Three different types of baffles are used to alter the radiative boundary conditions of the space that the flame resides: transparent, black, and reflective. By configurating sample/baffles in different ways, three burning scenarios are achieved and examined: double-sided, single-sided, and parallel burning samples. For each burning scenario, confinement levels (i.e., sample-baffle distance) are varied. In addition, the imposed flow speed is also varied to investigate its interplay with the confinement level. Through this, a rich dataset of flame spread is obtained. Different natures of flame spread (i.e., steady state, accelerating flame growth, and flame quenching) are observed when confined conditions vary. Flame characteristics (e.g., spread rate, flame length, flame shape) are also compared between different confined environments. To fully understand the experiment results, an inhouse three-dimensional transient Computational Fluid Dynamics (CFD) combustion model is utilized to conduct the numerical study. The model is first used to simulate the exact geometry of the ISS experiment. The effects of the confinement on solid burning behaviors observed in the experiments are successfully replicated by the numerical model. The model is then used to conduct parametric studies on the confinement levels and radiative reflection from surrounding walls. Through this, detailed profiles of the gas and solid phases are obtained. These include gas temperature, reaction rate contour, and heat fluxes on the sample surface. These profiles are compared between different cases and are used to help explain the burning behaviors observed in the ISS experiments.

Download or read book Safety and Health in Confined Spaces written by Neil McManus and published by Routledge. This book was released on 2018-12-18 with total page 916 pages. Available in PDF, EPUB and Kindle. Book excerpt: Safety and Health in Confined Spaces goes beyond all other resources currently available. International in scope, the 15 chapters and 10 appendices cover every facet of this important subject. A significant addition to the literature, this book provides a confined space focus to other health and safety concepts. Confined spaces differ from other workspaces because their boundary surfaces amplify the consequences of hazardous conditions. The relationship between the individual, the boundary surface, and the hazardous condition is the critical factor in the onset, outcome, and severity of accidents in these workspaces. The author uses information about causative and other factors from analysis of fatal accidents to develop a hazard assessment and hazard management system. He provides a detailed, disciplined protocol, covering 36 hazardous conditions, that addresses all segments of work--the undisturbed space, entry preparation, work activity, and emergency preparedness and response--and illustrates how to use it. Safety and Health in Confined Spaces gives you the tools you need for preventing and responding to accidents.

Download or read book Computational Fluid Dynamics in Fire Engineering written by Guan Heng Yeoh and published by Butterworth-Heinemann. This book was released on 2009-04-20 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fire and combustion presents a significant engineering challenge to mechanical, civil and dedicated fire engineers, as well as specialists in the process and chemical, safety, buildings and structural fields. We are reminded of the tragic outcomes of ‘untenable’ fire disasters such as at King’s Cross underground station or Switzerland’s St Gotthard tunnel. In these and many other cases, computational fluid dynamics (CFD) is at the forefront of active research into unravelling the probable causes of fires and helping to design structures and systems to ensure that they are less likely in the future. Computational fluid dynamics (CFD) is routinely used as an analysis tool in fire and combustion engineering as it possesses the ability to handle the complex geometries and characteristics of combustion and fire. This book shows engineering students and professionals how to understand and use this powerful tool in the study of combustion processes, and in the engineering of safer or more fire resistant (or conversely, more fire-efficient) structures. No other book is dedicated to computer-based fire dynamics tools and systems. It is supported by a rigorous pedagogy, including worked examples to illustrate the capabilities of different models, an introduction to the essential aspects of fire physics, examination and self-test exercises, fully worked solutions and a suite of accompanying software for use in industry standard modeling systems. Computational Fluid Dynamics (CFD) is widely used in engineering analysis; this is the only book dedicated to CFD modeling analysis in fire and combustion engineering Strong pedagogic features mean this book can be used as a text for graduate level mechanical, civil, structural and fire engineering courses, while its coverage of the latest techniques and industry standard software make it an important reference for researchers and professional engineers in the mechanical and structural sectors, and by fire engineers, safety consultants and regulators Strong author team (CUHK is a recognized centre of excellence in fire eng) deliver an expert package for students and professionals, showing both theory and applications. Accompanied by CFD modeling code and ready to use simulations to run in industry-standard ANSYS-CFX and Fluent software

Download or read book A Gallery of Combustion and Fire written by Charles E. Baukal, Jr. and published by Cambridge University Press. This book was released on 2020-09-03 with total page 193 pages. 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.
