This book was released on 1971 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: A basic investigation of supersonic mixing and combustion which is relevant to advanced propulsion concepts for a high Mach number, high altitude flight regime is described. A method of laboratory simulation is employed which is considered to be suitable for fundamental studies of diffusional-controlled mixing and combustion of confined coaxial streams of hydrogen and air under conditions approaching those of actual flight. A unique test facility consisting of a gas-fired, ceramic-brick air storage heater and an electrical-resistance hydrogen heater was used to generate test flow conditions at low static pressures, over wide ranges of temperature and velocity. Research studies have been carried out to obtain basic flow field data pertinent to the problem of turbulent mixing and combustion of heterogeneous gas streams under these conditions. Auto-ignition data from tests involving sustained combustion at an air Mach number of 2.6 are also presented. (Author).

Download or read book Combustion of Hydrogen in a Two dimensional Duct with Step Fuel Injectors written by James M. Eggers and published by . This book was released on 1978 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation of the combustion of hydrogen perpendicularly injected from step fuel injectors into a Mach 2.72, 2100 K vitiated test gas was conducted. The model simulated the flow between the center and side struts of an integrated scramjet module at Mach 7 flight and an altitude of 29 km. Parametric variation included equivalence ratio, fuel dynamic pressure ratio, and area distribution of the model. The overall area ratio of the model was held constant at 2.87. The data analysis indicated that no measurable improvement in mixing or combustion efficiency was obtained by varying the fuel dynamic pressure ratio from 0.79 to 2.45. Computations indicated approximately 80 percent of the fuel was mixed so that it could react; however, only approximately 50 percent of the mixed fuel actually reacted in two test configurations, and 74 percent in later tests where less area expansion of the flow occurred.

Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the proceedings of the Workshop on Com bustion, sponsored by the Institute for Computer Applications in Science and Engineering (ICASE) and the NASA Langley Research Center (LaRC). It was held on October 12-14, 1992, and was the sec ond workshop in the series on the subject. The first was held in 1989, and its proceedings were published by Springer-Verlag under the title "Major Research Topics in Combustion," edited by M. Y. Hussaini, A. Kumar, and R. G. Voigt. The focus of the second workshop was directed towards the development, analysis, and application of basic models in high speed propulsion of particular interest to NASA. The exploration of a dual approach combining asymptotic and numerical methods for the analysis of the models was particularly encouraged. The objectives of this workshop were i) the genesis of models that would capture or reflect the basic pllysical phenomena in SCRAMJETs and/or oblique detonation-wave engines (ODWE), and ii) the stimulation of a greater interaction between NASA exper imental research community and the academic community. The lead paper by D. Bushnell on the status and issues of high speed propulsion relevant to both the SCRAMJET and the ODWE parallels his keynote address which set the stage of the workshop. Following the lead paper were five technical sessions with titles and chairs: Experiments (C. Rogers), Reacting Free Shear Layers (C. E. Grosch), Detonations (A. K. Kapila), Ignition and Struc ture (J. Buckmaster), and Unsteady Behaviour ('1'. L. Jackson).

This book was released on 1974 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tests were conducted to determine the performance of a hydrogen burner used to produce a test gas that simulates air entering a scramjet combustor at various flight conditions. The test gas simulates air in that it duplicates the total temperature, total pressure, and the volume fraction of oxygen of air at flight conditions. The main objective of the tests was to determine the performance of the burner as a function of the effective exhaust port area. The conclusions were: (1) pressure oscillations of the chugging type were reduced in amplitude to plus or minus 2 percent of the mean pressure level by proper sizing of hydrogen, oxygen, and air injector flow areas; (2) combustion efficiency remained essentially constant as the exhaust port area was increased by a factor of 3.4; (3) the mean total temperature determined from integrating the exit radial gas property profiles was within plus or minus 5 percent of the theoretical bulk total temperature; (4) the measured exit total temperature profile had a local peak temperature more than 30 percent greater than the theoretical bulk total temperature; and (5) measured heat transfer to the burner liner was 75 percent of that predicted by theory based on a flat radial temperature profile.

Download or read book Mixing and Combustion of a Supersonic Fuel Jet and a Subsonic Coaxial Gas Stream written by John E Scott (Jr) and published by . This book was released on 1965 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation of mixing and burning is described in which the progress of mixing and burning is followed by observing the spatial variation of static pressure in the mixing duct. Experiments showed that the duct length required for mixing and for mixing with simultaneous chemical reaction of the gaseous fuel jet are identical and are independent of the amount to be mixed and burned. In order to aid in the interpretation of the experimental data, the flow field is assumed to be ''piecewise uniform'' over the mixing duct cross section. The analytical variation of the static pressure in the mixing agrees in a semi-quantitative manner with the experimental data. The experimental and analytical results are combined to provide the spatial and temporal variation of the mixing paramete. It is found that the combustion process has the general effect of increasing the mean duct velocity which increases the turbulent exchange coefficient and, hence, increases the mixing rate. For the experimental geometry considered, the mixing and burning time is roughly half of the time required for mixing only and is independent of the energy released in the chemical reaction.
