Class Details

Enrollment is being expanded; non-engineers with an interest in film, photography and fluids are particularly welcome. This is an upper division course, not suitable for first or second year students. Mechanical engineering students are expected to have had a course in fluids. The class is cross listed. Everybody will work together, and what each person brings to the table will be valued. My expectations will be tailored for students’ different backgrounds, but this is really a fail-safe course. What you get out of it depends on what you put in. See Is Flow Vis Right For You? for more info.

Fall 2022: Lecture MWF 12:20-1:10, ITLL 1B50. Lectures will also be zoomed and recorded, but in-person attendance is expected as much as possible. Zoom link will be in Slack and on Canvas.
