I studied the dynamics of droplet impact on liquid surfaces, specifically on water coated with a layer of crude oil. When raindrops impact the surface of an oil slick, tiny droplets are ejected from both the water and oil layers. These droplets are toxic to wildlife and can influence atmospheric cycles. To investigate this effect, I simulated droplet impact on oil slicks under various conditions using Basilisk, an opensource computational fluid dynamics software package. During this internship, I gained an appreciation for the power of numerical modeling to investigate problems that are difficult to recreate experimentally. I also developed my programming and data analysis skills. I not only learned new programming languages, but I also applied them in unanticipated ways. The work I did will heavily influence my senior thesis, for which I will explore other key phenomena associated with droplet impact in greater detail.
