概要

EXCIPLEX-based fluorescence thermometry was developed for remote probing of fuel droplet temperature. The fuel mixtures tested were n-heptane, n-decane and n-hexadecane which contained 1% naphthalene and 2.5% tetramethyl-p-phenylene diamine (TMPD). Also examined was unleaded regular gasoline into which no naphtalene or TMPD was dissolved. The fuel mixture suspended at the tip of a quartz fiber was allowed to evaporate in a stream of air or gaseous nitrogen, and its temperature was monitored using a fine thermocouple. The droplet was irradiated with a nitrogen laser and fluorescence emission spectra were taken by means of a light collection system which consisted of a convex lens, a light stop, a double monochromator and a photomultiplier. The results showed that remote probing of the droplet temperature could be achieved by measuring the ratio of fluorescence emission intensities at two different wavelengths.
