Image: Flow Visualization - A Course in the Physics and Art of Fluid Flow
Flow Visualization Home Galleries
2012 Gallery - Team 2
For most of the semester, students were put in mixed teams of graduate and undergraduate, photography and engineering. The teams were given access to a range of flow visualization equipment and experiments, and were also encouraged to create their own apparatus. Students worked both as artist plus assistants, and in fully collaborative arrangements, although each student was responsible for creative control of one image.
