G. Dode and published by . This book was released on 1984 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measurements of drop-size distributions and vaporized fuel concentrations have been combined with a spray model in the comparative study of the evaporation of sprays of emulsified and non-emulsified and non-emulsified (neat) fuels at elevated temperatures and pressures. The fuel spray was generated by a pressure jet atomizer and was polydisperse; the air stream was approximately one-dimensional turbulent flow in a constant area duct. Diagnostic techniques have been adapted or developed which allow rapid measurements of overall drop-size distributions in the presence of evaporation in high-temperature high-pressure air, and also the fuel vapor concentration distribution within sprays. It was concluded that even in conditions of turbulence and high Reynolds number for drop motion relative to the air, some emulsified fuel drops apparently undergo microexplosions. Further, it was determined that the initial atomization quality depends on te air conditions, with better atomization at higher air densities. This implies that spray drop-size measurements performed at atmospheric conditions need to be corrected for air density and temperature effects to predict atomization quality for altitude relight or high-pressure combustion. A spray model has been developed which represents the spray being studied and provides data in a form comparable to the experimental diagnostics.

Dodge and published by . This book was released on 1982 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report documents progress made during the second year of a three-year study of the atomization and evaporation characteristics of emulsified and alternative fuels at conditions typical of those found in gas turbine engines. The development of experimental techniques suitable for drop size measurements in realistic polydisperse fuel sprays in high pressure/temperature air has been the first goal of this year's program. The second area of interest has been the development of detailed drop models which predict the heat-up, evaporation, and trajectory of fuel sprays and the resulting size distribution parameters. In addition to these two areas, a facility was constructed during the first year of this program to allow for the containment of sprays in high pressure/temperature moving air with optical access for spray size measurements. These experimental and analytical tools have and will continue to be used to study the differences in atomization/evaporation of emulsified and neat fuels, and various other fuels at interest to the U.S. Navy.

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.

Available in PDF, EPUB and Kindle. Book excerpt: An investigation was made to understand the combustion behavior of heavy fuels (No. 4 and No. 6 oils) and their emulsions. This study is an extension of an earlier study on a distillate fuel (No. 2) and its emulsion, and has been carried out in four parts: (1) study of emulsion characteristics, (2) single drop combustion experiments of No. 4 oil and its emulsions; (3) spray experiments of No. 4 and No. 6 oils and their emulsions; and (4) theoretical studies of single drop combustion. The effects of water content and the coupling influences of injection temperature, chamber temperature, chamber pressure, chamber oxygen content, and injector opening pressure are examined. The results show that unsupported drops of emulsions of heavy fuels with water also undergo fragmentation. Disruption time of emulsion drop increases with gravity of the fuel and decreases with the increases of injection temperature, chamber oxygen concentration, and chamber temperature. It is also seen to attain a minimum value at a water content of about 8% (by volume) under the conditions of this study. The completeness of combustion, soot and nitrogen oxide emissions of the heavy fuel sprays are affected by emulsification. The first year's effort was presented in Report Nos. DOD/RSPA/DPB-50/80/1 and 80/2, dated January 1980, NTIS Nos. PB-80-178213 and PB-80-178221, respectively.

Available in PDF, EPUB and Kindle. Book excerpt: The Manual of Tests and Criteria contains criteria, test methods and procedures to be used for classification of dangerous goods according to the provisions of Parts 2 and 3 of the United Nations Recommendations on the Transport of Dangerous Goods, Model Regulations, as well as of chemicals presenting physical hazards according to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). As a consequence, it supplements also national or international regulations which are derived from the United Nations Recommendations on the Transport of Dangerous Goods or the GHS. At its ninth session (7 December 2018), the Committee adopted a set of amendments to the sixth revised edition of the Manual as amended by Amendment 1. This seventh revised edition takes account of these amendments. In addition, noting that the work to facilitate the use of the Manual in the context of the GHS had been completed, the Committee considered that the reference to the "Recommendations on the Transport of Dangerous Goods" in the title of the Manual was no longer appropriate, and decided that from now on, the Manual should be entitled "Manual of Tests and Criteria".
