Abstract

Streaked particle imaging velocimetry and sizing (SPIVS), an image based system for planar instantaneous measurement of two-component droplet velocity and size is demonstrated in the spray of a simplex atomizer. The SPIVS technique upgrades traditional double light pulse particle imaging techniques by overlaying particle streakings on the particle image pairs. The advantages of this system are the enhanced reliability of the droplet pairing process, the identification of the time sequence between images of a droplet image pair, and the ability to measure the size of individual droplets from the recorded scattered light energy. Measurements of droplet size and velocity in the solid cone spray of a simplex atomizer were conducted with both SPIVS and phase Doppler particle analyzer (PDPA) techniques. The results generated by these two systems are presented and discussed.
