Abstract.

The characteristics of a water mist, such as the droplet size and velocity distribution, the water mist atomization angle and the breakup length were determined with a newly developed nonintrusive pattern method, particle image velocimetry and sizing (PIVS), which is mainly based on the manipulation of digital particle images. A series of experiments were conducted using a semiconductor laser (with wavelength 650 nm and about 35–50-mW power), a plano–convex cylindrical lens and some other lenses to produce a light sheet approximately 1-mm thick. The typical results of a water mist under different conditions are shown in this paper.
