This project sought to characterize aspects of wave-breaking and turbulence in the ocean by simulating turbulent flows in a tank and describing the behavior of bubbles in still water and turbulent flow. When a wave breaks at the surface, turbulence and air bubbles are created. The resulting exchange of gas and energy at the air-sea boundary is an important dynamic. This experiment simulated and described these complex processes. This was done by using a high-speed camera and MATLAB to track the motion of the bubbles. Particle Image Velocimetry (PIV) was used to characterize the flow as well. We also employed MATLAB to develop software that tracked bubbles in the turbulent flow. We used a laser to cut out parts for the experiment, such as a stand for the needle in the tank. Throughout the internship, we learned a lot about the scientific process and how to function in a research lab. Furthermore, we learned a lot of programming skills, particularly in MATLAB. This experience reaffirmed my goal of going to graduate school and becoming a scientific researcher.
