Download Combustion Behavior of Solid Fuel Ramjets, Vol. II. Effects of Fuel Properties and Fuel-air Mixing on Combustion Efficiency Book in PDF, Epub and Kindle
Fundamental SFRJ fuel properties were determined using a DTA and a gas chromatograph for both high and low heating rates. The performance of these fuels was then measured under various operating conditions and test geometries. Fuel properties were found to have some effect on the obtainable combustion efficiency but much larger effects could be induced by the flow conditions (induced mixing near the fuel surface, bypass air, etc.). (Author).

Download Combustion Behavior of Solid Fuel Ramjets, Vol. 1. Correlation of Reacting and Non-reacting Flow Characteristics Book in PDF, Epub and Kindle
An experimental investigation was conducted to determine the 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 centerline turbulence intensity but not the near-wall turbulence intensity in cold flow. Near-wall turbulence profiles in cold flow were found to correlate with the fuel regression profiles in reacting flows. The use of bypass resulted in decreases in regression rate and efficiencies for all cases. (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).
