Paper Abstract

Evolving ideas of how high pressure atomization occurs, why it occurs, and what parameters might have a significant influence on atomization present some new and interesting challenges for measurement system. Of particular interest for transient fuel sprays is the region near the fuel injector tip itself, where the spray seems to begin the atomization process. This region of a spray is generally optically dense, has a large number of ligaments and non- spherical liquid elements, and probably has a large number of droplets as well. The high number density of liquid elements as well as absorption in the liquid makes optical probing of this region difficult. Reliable data in this region of the spray would be very useful for better understanding of the atomization process in these systems, as well as providing data for model validation for computer models being developed to approximate this behavior. This paper will try to briefly review the most common droplet sizing methods currently used with an emphasis on their performance in dense spray regions.
