Download or read book Backdraft Phenomena written by Charles Martin Fleischmann and published by . This book was released on 1993 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this project was to develop a fundamental physical understanding of backdraft phenomena. The research was divided into three phases: exploratory simulations, gravity current modeling, and quantitative backdraft experiments. The primary goal of the first phase was to safely simulate a backdraft in the laboratory. A half-residential-scale compartment was built to conduct exploratory experiments. The initial experiments concluded with a scenario describing the fundamental physics of backdrafts. The importance of the gravity current which enters the compartment after opening was identified. In the second phase, the gravity current speed and the extent of its mixed region was investigated in a series of scaled salt water experiments. The scaled compartment (0.3m x 0.1 5m x 0.1 5m) was fitted with a variety of end openings: full, slot, door, and window. Video and photo data indicate that the mixing layer which rides on the gravity current in the full opening case, expands to occupy nearly the entire current in the partial opening cases. The Froude number and nondimensional head height are independent of ~ and are in good agreement with numerical simulations and special limits from the literature. In the final phase, 28 backdraft experiments were conducted in a 1.2 m by 1.2 m by 2.4 m compartment. A methane burner was ignited inside a closed compartment and allowed to burn as long as oxygen was available. After the flame extinguished due to oxygen starvation, the burner was left on to allow the unburned fuel fraction to increase. Upon opening the hatch a gravity current enters the compartment and travels across the floor to the ignition source. After ignition a deflagration rips through the compartment and out the opening cul ninating in a large fireball. Histories recorded included: fuel flow rates, upper layer temperatures, lower layer temperatures, opening velocities, compartment pressures, upper layer species concentrations for O2, CO2, CO, and HC. Results indicate that unburned fuel mass fractions >15% are necessary for a backdraft to occur and that the backdraft severity strongly depends on the delay time and species concentrations.
Download or read book Focus on Combustion Research written by Sung Z. Jiang and published by Nova Publishers. This book was released on 2006 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Combustion or burning is an exothermic reaction between a substance and a gas to release heat. Combustion normally occurs in oxygen (often in the form of gaseous O2 ) to form oxides, However, combustion can also take place in other gases like chlorine. The products of such reactions usually include water (H2 O) as well as carbon monoxide (CO) or carbon dioxide (CO2 ), or both. Other by-products, such as partially reacted fuel and elemental carbon (C), may generate visible smoke and soot. This book presents leading research from around the world in this frontal field.
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.

Download or read book Advances in Construction Safety written by N. A. Siddiqui and published by Springer Nature. This book was released on 2022-10-31 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the details of computer-aided tools & techniques for improving work culture and minimizing accidents. The construction industry has been considered for employing the highest number of workmen but at the same time, it is also known as a poorly organized sector because of peculiarity in construction. Since construction project activity keeps changing on an hourly basis, it becomes difficult to manage the safety of workers or workplace and therefore, it stands as the second accident-prone industry. Several tools and techniques are introduced in controlling construction accidents concerning time and improvements are recorded. This book has briefly covered various challenges encountered, gaps in implementation, technological developments, and various methods/techniques to reduce construction accidents and highlights of research need for overall improvement of safety. This book is essentially helpful for students, researchers, faculty, and industry professionals.

Download or read book Ignitability and Explosibility of Gases and Vapors written by Tingguang Ma and published by Springer. This book was released on 2015-04-28 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book provides a systematic view on flammability and a collection of solved engineering problems in the fields of dilution and purge, mine gas safety, clean burning safety and gas suppression modeling. For the first time, fundamental principles of energy conservation are used to develop theoretical flammability diagrams and are then explored to understand various safety-related mixing problems. This provides the basis for a fully-analytical solution to any flammability problem. Instead of the traditional view that flammability is a fundamental material property, here flammability is discovered to be a result of the explosibility of air and the ignitability of fuel, or a process property. By exploring the more fundamental concepts of explosibility and ignitability, the safety targets of dilution and purge can be better defined and utilized for guiding safe operations in process safety. This book provides various engineering approaches to mixture flammability, benefiting not only the safety students, but also field operators, as a useful resource for the safe handling of flammable gases and liquids. It will be useful to anyone who worries about the ignition potential of a flammable mixture.
