Preliminary Study for the Modeling of an Artificial Icing Cloud.

Abstract

An evaluation was made of the essential features required to generate an effective model of an artificial icing cloud. Several alternatives were considered. A turbulent mixing length/integral method approach appears to be the most promising. A preliminary version of the fluid mechanical aspects of this model was developed and found to predict overall cloud sizes comparable to those observed during flight tests. Calculations of the radial velocity distributions in the cloud suggest that radial stratification of droplets according to size may occur (large droplets near the periphery and small droplets near the center). Recommendations for future work are included. (Author)
