Paper Abstract

Extraction of empirical water droplet impingement characteristics from records of wind tunnel dye-tracer experiments has been an extremely time consuming process in the past. Described are a method for extracting impingement data by measuring optical reflectance and a computer controlled laser reflectometer which was designed and built for making these measurements. The instrument increases the efficiency of the data extraction process by at least an order of magnitude. The accuracy of the reflectometer is discussed and some results obtained with the reflectometer are presented. The results are used to verify three-dimensional particle trajectory computer codes, which may then be used for design analysis and certification of aircraft anti-icing/de-icing systems.
