Hydrogen-fueled scramjets: Potential for detailed combustor analysis

Combustion research related to hypersonic scramjet (supersonic combustion ramjet) propulsion is discussed from the analytical point of view. Because the fuel is gaseous hydrogen, mixing is single phase and the chemical kinetics are well known; therefore, the potential for analysis is good relative to hydro-carbon fueled engines. Recent progress in applying two and three dimensional analytical techniques to mixing and reacting flows indicates cause for optimism, and identifies several areas for continuing effort

Application of a two-dimensional parabolic computer program to prediction of turbulent reacting flows

The capabilities of a computer program are explored, and computed results are compared with data. The comparisons are restricted to two-dimensional flows. Subsonic and supersonic flows, ducted and nonducted, reacting and nonreacting, are considered. An evaluation of models used for turbulence and chemical reaction was included. Constants in the dissipation rate of turbulent kinetic energy, turbulence model, which produces mixing in good agreement with data, are the same for all calculations. Experimental data are reported for coaxial injection at matched pressure (1 atm or 101.3 kPa) of a cold, Mach 2, hydrogen jet into a hot, Mach 2, vitiated airstream. Profiles of pitot pressure and gas composition obtained from water cooled probes are reported and compared with theoretical results

Conflict of Laws in Multistate Fraud and Deceit

Unlike most conflict of laws questions, the choice-of-law problem in tort actions based on multistate fraud and deceit has been given surprisingly little attention. Until recent years the problem had been raised in but two or three reported cases, and no real attempt had been made to analyze and clarify it. The recognition and scanty treatment of the problem in the Restatement of Conflict of Laws\u27 has perhaps been primarily responsible for the growing awareness of it in the courts in the past two decades. Nevertheless, neither the courts nor the secondary authorities have come forward with a thorough study and analysis or a clear and uniform treatment. Perhaps both the frequent failure to face the problem squarely and the scarcity of serious efforts to treat it may be mainly attributed to the extremely elusive and perplexing nature of the problem itself. No doubt in some cases it has been overlooked or avoided. Yet in view of the constant increase in inter-state transactions and the diversity of domestic laws with respect to the elements of a cause of action for deceit, there is every indication that the problem will become increasingly important

Arkansas Cotton Variety Test 2012

The primary goal of the Arkansas Cotton Variety Test is to provide unbiased data regarding the agronomic performance of cotton varieties and advanced breeding lines in the major cotton-growing areas of Arkansas. This information helps seed companies establish marketing strategies and assists producers in choosing varieties to plant
