Presentation Transcript

  1. REU Novel Advanced Materials 2010 Comprehensive jp8 mechanism for vitiated flows Kelsey Hall, University of Pennsylvania

  2. Purpose of research • Evaluate efficiency, combustion characteristics of commercial fuels • Energy Conservation • Environmental Concerns • JP8: Jet Propellant • Liquid hydrocarbon fuel • 4 to 16 C http://www.powerjets.co.uk/images/f-16-afterburner.jpg

  3. Long Term Objectives • Extend m-Xylene model to include low pressure parameters • Comprehensive chemical kinetic model of JP8 combustion • Conditions of jet engine afterburner

  4. Immediate Objectives • Optimize experimental setup • Isokinetic sampling • N2 shield • Validate method • Simple hydrocarbon fuels • Heptane modeling: more complex

  5. Counterflow Diffusion Flat Flame Burner

  6. Sampling Methods Silicon tube O.D.: 350 microns Quartz probe O.D.: 3.5 mm

  7. Flames Methane Heptane Quartz probe Silicon tube

  8. Simulation • Chemkin • OPPDIF • Chemistry model ref. Brezinsky shock tube lab OPPDIF user manual

  9. CH4 Flame Results Condition CH4 0.4L/min, N2(fuel side) 1.6L/min, O2 0.7L/min, N2 1L/min

  10. Heptane Flame Results N-heptane simulation using OPPSMOKE, mech. provided by Paolo Berta
