    Abstract

    Experiments were conducted to measure droplet sizes and their distribution in high-pressure diesel fuel sprays. Fuel droplets were collected on glass plates which were treated with surface modifier. The droplets were photographed and subsequently analyzed on an image analyzer. The resultant information is used to calculate average diameter, Sauter mean diameter, etc. The degree of automation in the analysis process allows accurate measurement of a large number of photographed drops. It is estimated that the method used here allowed good measurements of small droplets on the order of 0.5 µm. Typical output of the analysis together with the validity of the technique is presented in the paper.
