This present experiment developed a method for simultaneously measuring vapor concentration, droplet size and velocity in a spray by simultaneous application of LIF and ILIDS. To combine these two measurement techniques, we employed a Nd : YAG laser with a special optical arrangement in order to emit the laser beam at two wavelengths : one at 266nm to excite the fluorescence marker of acetone for LIF and a second at 532nm to illuminate the droplets for ILIDS. As the wavelengths of fluorescence differ from the scattered light at 532nm, the use of optical filters enables one to distinguish fluorescence from scattered ligh. The experimental results showed the diffusion of a vapor concentration and the difference of droplet motions classified by the droplet diameter.
