Abstract:
Co-annular smoke-free laminar diffusion wick-fed flames
of aviation bio-paraffins and their blended with various
amounts of propylbenzene of 10, 20, 25 Vol.% have been
used to study soot formation. A light extinction method
is adopted to determine the total soot volume (TSV) as a
function of flame height (FH) and fuel mass consumption
rate (FMCR). The empirical models have been built to
predict aviation bioparaffins/propylbenzene (Bio-P/PB)
mixtures as the function of two variables of FMCR and
concentration of propylbenzene content (%PB). TSVs of
Bio-P/PB mixtures increase with increasing flame height,
FMCR and %PB. The effect of flame height, FMCR and
concentration of propylbenzene content on soot formation
are respectively expressed as the quadratic, power law
and linear functions. The results of current work create
a database for optimizing the trade-off impacts of
aromatic in aviation biofuel. This information is of
high importance when blending aromatic to aviation
bio-paraffins, which is produced from triglycerides and
fatty acids in the vegetable by hydrotreating process,
for using as a fuel in aircraft engines.
