Abstract : The goal of this work is to construct an experimental facility for conducting experiments on combustion of Jet fuels at elevated pressures up to 60 bar. Using support provided previously by the U.S. Army Research Office (ARO) a High Pressure Combustion Experimental Facility'' (HPCEF) was constructed for carrying out for carrying out experimental studies on combustion of a wide variety of gaseous and liquid hydrocarbon fuels, including commercial fuels for example JP-8 and Jet A, at pressures up to 30 bar. In view of the success of these previous studies at elevated pressures up to 30 bar, additional funding was received from ARO to extend the maximum operating pressure of HPCEF from 30 bar to 60 bar. Several systems are integral to the facility. They include the flow control system, gas-supply system, the ignition system, the exhaust system, the cooling system, and the pressure control system. All these systems were successfully upgraded. The US Army is currently developing technologies to facilitate diesel-powered equipment and equipment employing spark-ignition combustion (for example Unmanned Aerial Vehicles) to be powered by JP-8. The HPCEF will make a significant contribution in providing fundamental knowledge on aspects of combustion at high pressures. This will provide the foundation for developing the technologies necessary for the conversion. The useful life of the HPCEF is estimated to be twenty years.
