抄録

Laser induced fluorescence method has been employed for the remote, non-intrusive and instan­taneous measurements of a fuel droplet flame under microgravity. A fuel droplet was doped with naphthalene and TMPD (N,N,N',N'-Tetramethyl-1,4--phenylendiamine). The fluorescene emis­ sion spectra from a droplet subjected to the incident nitrogen laser were measured with an image in­ tensified optical multichannel analyzer. The microgravity was generated in a capsule of the MGLAB (Micro-Gravity Laboratory of Japan) drop shaft. The results showed that the newly developed diagnostic system was found to be applicable successfully for the simultaneous measurements of diameters of droplet, flame and soot shell under microgravity. A droptet temperature could be determined from the measured result of the ratio of fluorescence emission intensities at two different wavelengths. The soot shell was located at the vicinity of the droplet surface at the early stage of the burning and moved away from the droplet with the lapse of time.
