I studied the rise velocity of large viscous bubbles<br />
in a narrow tube, which closely model bubbles in<br />
a volcanic eruption. Factors such as gravitational<br />
forces, surface tension, viscosity and tube<br />
diameter influence a bubble’s rise velocity and<br />
appearance. To understand how these bubbles<br />
behave, I ran simulations using Basilisk, a<br />
software program that solves partial differential<br />
equations using adaptive Cartesian meshes. I<br />
then created movies and graphs from the output<br />
to display the relationship between the bubbles'<br />
rise velocity and their fluid properties. Through<br />
this internship, I sharpened my data analysis<br />
and coding skills and became familiar with new<br />
programming languages. I also gained a more<br />
thorough understanding of fluid dynamics,<br />
which I find fascinating. Although my research<br />
did not directly relate to my academic study, the<br />
technical and problem-solving skills I developed<br />
will be helpful in my future independent work.<br />
