The purpose of the given document is to remind the reader of goals initially set in conjunction with the ORCA Grant project proposal in October 2016, to present experimental findings obtained during the grant period, and to discuss the results of the work and their implications for future investigations. As stated in the proposal, the main purpose of this ORCA project was to compare the droplet atomization (expulsion of a fine spray) of various water-glycerol mixtures upon impact on superheated, superhydrophobic surfaces. The major goal to that end was to use a certain unique experimental procedure in quantifying the data obtained. This methodology involves capturing droplet impact of glycerol solutions onto a hot superhydrophobic wafer using high-speed digital imaging and then using computer vision algorithms to process each frame (see Figure 1) and quantify the intensity of secondary atomization as a function of time and temperature. The final goals stated in the project proposal were for the research to result in a publication in a certain international journal and a poster at the APS Division of Fluid Dynamics International Conference this past November. As of December 2017, I am preparing my body of material for submission to the journal. However, I did not attend the APS conference, having moved to Russia in August upon acceptance into the 2017-2018 school year of the Math in Moscow program. Academic outcomes aside, the laboratory work itself brought a measure of success and scientific insight.
