Abstract:

Dataset supporting publication in the Journal of Fluid Mechanics by Murphy et al (2015). This data set contains raw data and analysis of an experimental laboratory study examining splash behavior and oily marine aerosol production by raindrops impacting oil slicks. The raw data consist of .tif images from high speed visualizations (used to describe and classify splash processes) and high speed holography (used to measure airborne droplet sizes). Images (.tif) used for measurement of interfacial and surface tension of various oils via the pendant drop method are also included, as are Excel spreadsheets with analysis of the data.
