Abstract
Droplet lasing spectroscopy (DLS) has been applied to the measurement of droplet size and vaporization rates in both reacting and non-reacting rectilinear droplet streams. A Berglund-Liu droplet generator was used to generate a stream of droplets, approximately 63 microns in diameter and 6.5 droplet diameters apart. Ethanol, methanol, and a pentane/ethanol mixture were doped with Rhodamine 6G. Lasing spectra were examined in the steady- state combustion regime. In the pentane/ethanol case the measurements were carried out in a sooting region of the flame. In some cases, vaporization rates were high enough to measure the rate from consecutive droplets, yielding a quasi-instantaneous measurement. In all cases, the D2 law of droplet vaporization was evident. In addition photographs of the flames yielded measurements of flame height and thickness.
