Approved for public release; distribution unlimitedAn 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 : Brian Andrew Binn. The combustion characteristics of petcoke and imported coal and their respective chars under oxy-fuel (21% O 2 /79% CO 2) and oxygen-enriched oxy-fuel (30% O 2 /70% CO 2) environments were investigated by using non-isothermal thermogravimetric method coupled with a Fourier transform infrared mental results reveal that at elevated oxygen levels, profiles shift to lower Cited by: 5. Solid fuel ramjets (SFRJ) are known for their operational simplicity and high specific impulse. The performance of the SFRJ propulsion system is directly tied to the energy density and combustion behavior of the fuel. A typical solid fuel used in a ramjet application is a collection of metal particles suspended in a polymeric by: Combustion characteristics and turbulence modeling of swirling reacting flow in solid fuel ramjet Acta Astronautica, Vol. Pyrolysis-gas chromatography mass spectroscopy and pipe combustor analysis of the ignition and mass regression characteristics of a sulfur doped polysulfide ramjet fuelCited by:
During the same period of time, in Israel Institute of Technology, several investigations aimed to study solid fuel ramjets as experimental and analytical investigation of a small solid fuel ramjet combustor, theoretical analysis of the similarity and scale effects in solid-fuel ramjet combustors, theoretical works on combustion characteristic of boron-fueled solid fuel ramjets with aft-burner and with and Cited by: 7. The potential energetic performance of fuel ingredients for the use in the solid fuel ramjet is presented in terms of the enthalpy of combustion per unit mass and per unit volume of the fuel. Combustion phenomena and combustion efficiency are briefly discussed, but are not accounted for in evaluating the theoretical fuel performance.
