description | The personnel, publications and important research results of the three year grant on the control of soot formation are presented in this final report. Systematic probing of the ethene diffusion flame at various N2/fuel dilution ratios using thermophoretic sampling has revealed the variation of height within the flame at which soot precursor particles are converted to carbonaceous aggregates. The measurement of temperature on the axis of the flame at various dilution ratios has been accomplished. The use of the laser microprobe mass spectrometer at the NIST to analyze the samples of soot precursor material and carbonaceous soot has provided the chemical evolution of soot in flames. These results provide the rate of the carbonization of soot precursors. The species found correspond to the stabilomers predicted by earlier thermodynamic calculations. jg p.5 |
