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.
If you are interested, you can consider this an open course. All the materials you need are provided here; textbook, lecture notes, lecture videos, and assignments. I won’t be able to post your images here, but you could post them on the Facebook Flow Visualization group, and get informal feedback from the community. If you attempt this, please drop me a line: hertzberg@colorado.edu. I’ll help you in any way I can.
Fall 2024: 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.

Office: ECME 220
Office hours: Right after class, nearby. Or email me for an appointment in my actual office, in ECME 220. Monday and Friday afternoons and early evenings are best, and Tuesday Thursday via zoom. I love to look at student work and hear about your setups and plans! I won’t edit for you, but I’ll counsel you through your own editing process.
TA:Anjali Shadija <AnjaliSanjaykumar.Shadija@colorado.edu> can help you with WordPress, Canvas, photography, video editing and administrative stuff.
