Available in PDF, EPUB and Kindle. Book excerpt: Several characteristic times are identified for describing force-ventilated enclosure fires. Using the initial properties of an enclosure and a prescribed fire heat release rate, a set of appropriate times for hazard evaluation can be calculated. Three times, characteristic of the histories of the mass of gas in the room, the energy in the room, and the response of the enclosure walls, are proposed, defined, and tested. These parameters are independent indicators of quasi-steady conditions in force-ventilated enclosure fires.

Download or read book Progress in Scale Modeling written by Kozo Saito and published by Springer Science & Business Media. This book was released on 2008-08-20 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scale modeling can play an important role in R&D. When engineers receive some ideas in new product development, they can test how the new design looks by bui- ing scale models and they can get an actual feeling with the prototype through their imagination. Professor Emori often said: “When children play with a toy airplane, their mind is wondering about the prototype airplane which they haven’t ridden. ” Children can use the scale model airplane as a means to enter into an imagi- tive world of wonder by testing in their own way how the actual airplane might function, how the actual airplane can maneuver aerodynamically, what might be the actual sound of a jet engine, how to safely land the actual airplane, and so on. This imagination that scale models can provide for children will help them later develop professional intuition. Physical scale models can never be entirely succe- fully replaced by computer screens where virtual models are displayed and fancy functions are demonstrated. Not only children but also adults can learn things by actually touching things only offered by physical models, helping all of us develop imagination and feeling eventually leading toward Kufu. Einstein’s famous “thought experiments [11],” which helped him to restructure modern physics may possibly and effectively be taught by letting researchers play with scale models!? References 1. I.

This book was released on 1997-09-18 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: The reduction of the fire hazard of fuel is critical to improving survivability in impact-survivable aircraft accidents. Despite current fire prevention and mitigation approaches, fuel flammability can overwhelm post-crash fire scenarios. The Workshop on Aviation Fuels with Improved Fire Safety was held November 19-20, 1996 to review the current state of development, technological needs, and promising technology for the future development of aviation fuels that are most resistant to ignition during a crash. This book contains a summary of workshop discussions and 11 presented papers in the areas of fuel and additive technologies, aircraft fuel system requirements, and the characterization of fuel fires.

Download or read book Fluid Mechanics Aspects of Fire and Smoke Dynamics in Enclosures written by Bart Merci and published by CRC Press. This book was released on 2022-10-24 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides essential understanding of flows in fire and smoke dynamics in enclosures, covering combustion, heat transfer and fire suppression in more detail than other introductory books. It moves from the basic equations for turbulent flows with combustion, through a discussion of the structure of flames, to fire and smoke plumes and their interaction with enclosure boundaries. This is then applied to fire dynamics and smoke and heat control in enclosures. This new edition provides considerably more on the fluid mechanics of the effect of water, and on fire dynamics modelling using Computational Fluid Dynamics. Presents worked examples taken from practical, everyday fire-related problems Covers a broad range of topics, from the basics to state-of-the-art computer simulations of fire and smoke-related fluid mechanics, including the effect of water Provides extensive treatment of the interaction of water sprays with a fire-driven flow Contains a chapter on Computational Fluid Dynamics, the increasingly popular calculation method in the field of fire safety science The book serves as a comprehensive guide at the undergraduate and starting researcher level on fire and smoke dynamics in enclosures, with an emphasis on fluid mechanics.

Download or read book Experimental and Computational Characterization of Strong Vent Flow Enclosure Fires written by Craig George Weinschenk and published by . This book was released on 2011 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: Firefighters often arrive at structures in which the state of fire progression can be described as ventilation-controlled or under-ventilated. This means that inside the enclosure the pyrolyzed fuel has consumed most, if not all of the available oxygen, resulting in incomplete combustion. Under-ventilated (fuel rich) combustion is particularly dangerous to occupants because of the high yield of toxins such as carbon monoxide and to firefighters because once firefighters enter the structure and introduce oxidizer, the environment can rapidly change into a very dangerous, fast burning condition. The fuel load in many compartment fires would support a several megawatt fire if the fire were not ventilation controlled. In the process of making entrance to the fire compartment, firefighters will likely provide additional ventilation paths for the fire and may initiate firefighting tactics like positive pressure ventilation to push the hot flammable combustion products out of the attack pathway. Forced ventilation creates a strongly mixed flow within the fire compartment. Ventilation creates a complex fluid mechanics and combustion environment that is generally not analyzed on the scale of compartment fires. To better understand the complex coupling of these phenomena, compartment scale non-reacting and reacting experiments were conducted. The experiments, which were conducted at The University of Texas at Austin's fire research facility, were designed to gain insight into the effects of ventilation on compartment thermal characteristics. Computational models (low and high order) were used to augment the non-reacting and reacting experimental results. Though computationally expensive, computational fluid dynamics models provided significant detail into the coupling of buoyantly driven fire products with externally applied wind or fan flow. A partially stirred reactor model was used to describe strongly driven fire compartment combustion processes because previously there was not an appropriate low dimensional computational tool applicable to this type of problem. This dissertation will focus on the experimental and computational characterization of strong vent flows on single room enclosure fires.

Book excerpt: An approximate modeling technique for enclosure fires is proposed and partially tested. The technique is based on the hypothesis that the combustion of a fuel pile in a enclosure, relative to the combustion of the same pile in open space (unconfined), depends on associated differences in the fluid-mechanical properties and the chemical composition of the gas supply to the fire.

Download or read book Sprinklers and Smoke Management in Enclosures written by Dalia E.E. Khalil and published by CRC Press. This book was released on 2020-05-14 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses smoke management in enclosures and provides a platform for understanding the principles of smoke propagation and spread, heat release rate, and the effect of sprinklers on suppression. Considering how sprinkler systems have become a vital part of firefighting systems in enclosures, the book evaluates the effect of sprinkler activation on the behavior of fire-induced smoke and the interaction of water particles with the smoke layer. It studies two base case models where the sprinklers’ effect on the fire curve was considered. This base case was assessed with two smoke extraction systems, namely, a ducted system and an impulse ventilation system. By focusing on key elements, such as visibility, ceiling height, and fire curve, the results of the study will be of interest to mechanical engineers, HVAC professionals, and fire safety professionals and investigators. Features Includes case models and scenarios to evaluate real examples from different applications Studies the effect of sprinkler activation on the behavior of fire-induced smoke Explores various factors, such as ceiling height, sprinkler operating pressure, and fire curve Discusses the interaction of water particles with the smoke layer Utilizes Pyrosim software for CFD modeling
