Abstract:The goal of this study is to develop, conduct, and analyze advanced laser and optical measurements in the referee combustor (WPAFB, Bldg. 490, RC 152) selected by the ASCENT National Fuel Combustion Program. We will conduct advanced spatially resolved high-speed Planar imaging as well as other advanced diagnostic measurements which can provide insight into the physicochemical response of the combustion process for various alternative fuels. Moreover, the results will provide data for development of new predictive combustion models in ASCENT. Once fully characterized, the standard referee combustor rig can streamline and simplify fuel certification procedures outlined in the ASTM D4054 (Standard Practice for Qualification and Approval of New Aviation Turbine Fuels and Fuel Additives) through minimization of full-scale engine testing.
The main objectives of the work in this proposal are to work with UDRI and AFRL in carrying out diagnostics measurements for the referee combustor. The following tasks will guide this collaboration:
• Identify the operating conditions and key parameters for detection in the referee combustor
• Evaluate and modify the referee combustor at AFRL for laser and optical diagnostics
• Design laser and optical diagnostics setup and assist in the fuel screening process
• Analyze data and pass on data to modeling groups in combustion program.
