Book excerpt: An experimental investigation was conducted on methane, laminar-jet, diffusion flames with coaxial, forced-air flow to examine flame shapes in zero-gravity and in situations where buoyancy aids (normal-gravity flames) or hinders (inverted-gravity flames) the flow velocities. Fuel nozzles ranged in size from 0.051 to 0.305 cm inside radius, while the coaxial, convergent, air nozzle had a 1.4 cm inside radius at the fuel exit plane. Fuel flows ranged from 1.55 to 10.3 cu cm/sec and air flows from 0 to 597 cu cm/sec. A computer program developed under a previous government contract was used to calculate the characteristic dimensions of normal and zero-gravity flames only. The results include a comparison between the experimental data and the computed axial flame lengths for normal gravity and zero gravity which showed good agreement. Inverted-gravity flame width was correlated with the ratio of fuel nozzle radius to average fuel velocity. Flame extinguishment upon entry into weightlessness was studied, and it was found that relatively low forced-air velocities (approximately 10 cm/sec) are sufficient to sustain methane flame combustion in zero gravity. Flame color is also discussed. Haggard, J. B., Jr. Glenn Research Center NASA-TP-1841, E-487 RTOP 506-55-22

Book excerpt: This book provides an introduction to understanding combustion, the burning of a substance that produces heat and often light, in microgravity environments-i.e., environments with very low gravity such as outer space. Readers are presented with a compilation of worldwide findings from fifteen years of research and experimental tests in various low-gravity environments, including drop towers, aircraft, and space.Microgravity Combustion is unique in that no other book reviews low- gravity combustion research in such a comprehensive manner. It provides an excellent introduction for those researching in the fields of combustion, aerospace, and fluid and thermal sciences.* An introduction to the progress made in understanding combustion in a microgravity environment* Experimental, theoretical and computational findings of current combustion research* Tutorial concepts, such as scaling analysis* Worldwide microgravity research findings

Book excerpt: Visualization is a novel interdisciplinary science for making any phenomenon clear by visualizing the invisible using computer techniques. The Atlas of Visualization presents the latest advances in visualization techniques, image processing, computer graphics, and visualization of measured and compound results. Focusing on both experimental and computer-aided visualization, this encyclopedic resource discusses all aspects of this new and evolving science. This volume includes cutting-edge information on turbulent flow, vortex, water spray, PIV, jet flames, thermal plume and numerical simulation, and heat and mass transfer. Encompasses all aspects of visualization! The Atlas of Visualization is concerned with all aspects of visualization, not just with engineering and physics applications, but with applications in disciplines such as the biomedical sciences, oceanography, agriculture, meteorology, and sports science. The aim of this book is to provide a medium for announcing the latest advances in visualization. Full color presentation! Books on visualization could not discuss complex phenomena without the use of color photographs. For this reason, the Atlas of Visualization is issued in full color. This allows the complex phenomena to be presented clearly, and combined phenomena are illustrated with quantitative results and detailed structure. Global perspective! The chapters and gravures in the Atlas are contributed by the world's top researchers, and provides both researchers and technicians with extremely useful information from the foremost innovators in the field of visualization. Computer scientists, mechanical engineers, physicists, applied and biological scientists, meteorologists, and sports scientists, as well as students of these disciplines, will find the Atlas of Visualization an essential source of all the latest knowledge in the field of visualization.

This book was released on 2006 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unforced and strongly forced cold-flow jets are simulated using a higher order finite volume CFD code. The jet was forced by varying the jet exit velocity over a range of forcing amplitudes and frequencies and it was found that the jet Strouhal number (St) was the important parameter in characterizing flowfield development. Further, the forced jets showed increased entrainment and increased entrainment rates as compared to the non-forced jets.
