Download Effect of Configuration Variables on Performance of Solid Fuel Ramjets Book in PDF, Epub and Kindle
An experimental investigation into the effect of configuration variables on combustion performance in the solid fuel ramjet was conducted. The effect of air ducting methods on combustion efficiency was found to be dependent not only on the flow rates, momentum and geometry of the system but also on the composition of the solid fuel. High pressures and low air mass fluxes through the fuel grain affect the regression rate by altering the heat transfer mechanism. Some air duct configurations were found to create a favorable environment for combustion pressure oscillations. (Author).

Download An Investigation of the Combustion Behavior of Solid Fuel Ramjets Book in PDF, Epub and Kindle
An experimental and analytical investigation was conducted of the combustion behavior in solid fuel ramjets. The effects of configuration variables on combustion performance were experimentally determined. Air ducting methods were found to affect combustion efficiency through port flow rates, bypass dump momentum and geometry and bypass ratio. Bypass configurations with plexiglas fuel altered the heat transfer mechanisms within the port and decreased combustion efficiency. The analytical model was found to be in qualitative agreement with experimental data. Finite rate kinetics and radiative transfer to the fuel surface will be required in the model to obtain more quantitative accuracy. (Author).

Download A Comparison of Solid Fuel Ramjet Flow Characteristics and Combustion Behavior Book in PDF, Epub and Kindle
An experimental investigation was conducted to determine if there is a relationship between the cold flow characteristics of velocity, pressure distribution, and turbulence intensity and the reacting flow performance and combustion characteristics of a solid fuel ramjet. The effects of configuration and air flow changes on the above characteristics were examined. Average regression rates and combustion efficiencies were not significantly affected by changes in configuration. These variations in test conditions significantly affected the center-line turbulence intensity but not the near-wall turbulence intensity in cold flow. The use of bypass resulted in decreases in regression rate and efficiencies for all cases. Attainable performance appears to be most strongly related to near-wall turbulence intensity/mixing and to the amount of fuel reaching the aft mixing chamber. (Author).

Download Masters Theses in the Pure and Applied Sciences Book in PDF, Epub and Kindle
Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 23 (thesis year 1978) a total of 10,148 theses titles from 27 Canadian and 220 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. While Volume 23 reports these submitted in 1978, on occasion, certain universities do report theses submitted in previous years but not reported at the time.
