This book was released on 2009 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: The atomization mechanism of Gelled Hypergolic Propellants (GHPs) in an impinging jet flow field is significantly different from that of non-gelled liquid propellants and is not clearly understood. In this study, rheologically matched non-Newtonian fluids which are non-reactive and non-toxic were used to act as a simulants for the gelled hypergolic propellants. A Newtonian fluid has been used as a simulant for liquid propellants and to act as a comparison standard for the non-Newtonian simulants. This study explored the effect of nozzle geometry such as orifice inlet shape and aspect ratio on the jet stream surface dynamics and the break up process before and after doublet jet impingement, respectively. Gels produced, using polymer or particle gellants, displayed less disturbed surfaces than non-gelled fluids, due to increased viscosity. As a result, for a given flow rate the sheet formed by impinging jets was much more stable and the sheet break up length was greater for gelled-water than non-gelled water jets. The nozzle aspect ratio has more noticeable effects on the near-field jet stream characteristics for both fluids than the orifice inlet shape. The longer nozzles form a more stable jet stream which delays the break-up of the sheet, leading to greater break up lengths than the shorter nozzles. For similar Reynolds number, droplet size for gelled water is much smaller than that for non-gelled water. Also, impinging jets employing gelled water produce sprays which are distributed over a wider space and in a wider range of droplet sizes than the jets with non-gelled water.

This book was released on 1993 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study examining impinging liquid jets has been underway to determine physical mechanisms responsible for combustion instabilities in liquid bi-propellant rocket engines. Primary atomization has been identified as an important process. Measurements of atomization length, wave structure, and drop size and velocity distribution were made under various ambient conditions. Test parameters included geometric effects and flow effects. It was observed that pre-impingement jet conditions, specifically whether they were laminar or turbulent, had the major effect on primary atomization. Comparison of the measurements with results from a two-dimensional linear aerodynamic stability model of a thinning, viscous sheet were made. Measured turbulent impinging jet characteristics were contrary to model predictions; the structure of waves generated near the point of jet impingement were dependent primarily on jet diameter and independent of jet velocity. It has been postulated that these impact waves are related to pressure and momentum fluctuations near the impingement region and control the eventual disintegration of the liquid sheet into ligaments. Examination of the temporal characteristics of primary atomization (ligament shedding frequency) strongly suggests that the periodic nature of primary atomization is a key process in combustion instability.

Available in PDF, EPUB and Kindle. Book excerpt: Annotation Since the invention of the V-2 rocket during World War II, combustion instabilities have been recognized as one of the most difficult problems in the development of liquid propellant rocket engines. This book is the first published in the United States on the subject since NASA's Liquid Rocket Combustion Instability (NASA SP-194) in 1972. In this book, experts cover four major subject areas: engine phenomenology and case studies, fundamental mechanisms of combustion instability, combustion instability analysis, and engine and component testing. Especially noteworthy is the inclusion of technical information from Russia and China--a first.

Book excerpt: Atomization and Sprays examines the atomization of liquids and characteristics of sprays. It explains the physical processes of atomization as well as guidelines for designing atomizers. In addition, it demonstrates how the importance of the size and velocity of a particle contributes to improved spray characterization. Coverage includes general considerations, drop size distribution of sprays, flow in atomizers, atomizer performance, external spray characteristics, drop evaporation, and drop sizing methods.

Available in PDF, EPUB and Kindle. Book excerpt: The second edition of this long-time bestseller provides a framework for designing and understanding sprays for a wide array of engineering applications. The text contains correlations and design tools that can be easily understood and used in relating the design of atomizers to the resulting spray behavior. Written to be accessible to readers with a modest technical background, the emphasis is on application rather than in-depth theory. Numerous examples are provided to serve as starting points for using the information in the book. Overall, this is a thoroughly updated edition that still retains the practical focus and readability of the original work by Arthur Lefebvre.
