| Research Abstract |
Laser induced fluorescence method was applied for the visualization of Volatile Organic Compound (VOC) gas. Fourth-harmonic generation light of ND : YAG laser was used for the excitation of the VOC gas. An image intensifier (I/I) was used for capturing the VOC fluorescence images. Diffusion characteristics of VOC from suspended droplets of xylene and toluene were investigated. Moreover, VOC images from a droplet deposited on a wall and a spray flow were visualized by this method. Measurement results were compared with the solutions of the one-dimensional diffusion equation. As the result, it was confirmed that the diffusion phenomena could be analyzed by the LIF method.
