Learning about fluids as a physics major

Click For Summary

Discussion Overview

The discussion revolves around the inclusion of fluid mechanics in the curriculum for physics majors. Participants explore when and how fluid dynamics is taught, the perceived importance of the subject, and the availability of relevant courses at various universities.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Meta-discussion

Main Points Raised

  • Some participants note that fluid mechanics is typically not covered in standard physics curricula, with one mentioning learning it through a special topics class and self-study.
  • Others suggest that fluid mechanics is often found in mechanical engineering departments and may be included in graduate programs rather than undergraduate physics courses.
  • One participant questions whether fluid mechanics is considered a vital part of the physics curriculum, indicating a lack of consensus on its importance.
  • Another participant references an article by Jerry Gollub that discusses the teaching of fluids, suggesting that there are differing opinions on how essential the topic is for physics education.
  • Concerns are raised about the prerequisites for learning fluid mechanics, with some expressing frustration over the reliance on self-study due to the absence of dedicated courses.
  • One participant mentions that while some universities offer fluid mechanics courses, many do not, and there is a perceived need for more comprehensive classes that include fluid dynamics and continuum mechanics.
  • There is a suggestion that the lack of a good textbook may contribute to the absence of fluid mechanics courses in undergraduate programs.

Areas of Agreement / Disagreement

Participants generally agree that fluid mechanics is not widely taught in physics programs, but there is disagreement regarding its importance and the reasons for its absence in the curriculum. Multiple competing views on the necessity and availability of fluid mechanics education remain unresolved.

Contextual Notes

Limitations include the variability of course offerings across institutions and the dependence on individual university curricula. There are also unresolved questions about the prerequisites for learning fluid mechanics and the availability of suitable textbooks.

Hopefully I'm posting this in the correct forum but I was just wondering, when would would a physics major learn about fluids? We covered it a little bit in high school but I don't see fluids at all in my university's curriculum.
 
Physics news on Phys.org
General Physics 3 has an introduction to fluids. A course specifically on fluid mechanics, from what I can tell, is usually found in the mechanical engineering department. I'm also finding that it's often listed as part of a grad program.

My university (Towson) doesn't have a class specifically for fluids, either.
 
The typical physics curriculum does not cover fluid mechanics. I learned it via a "special topics" class with my advisor, a mechanical engineering class (continuum mechanics), and on my own.
 
Really? Why is that? Is fluid mechanics not considered a vital part of the physics curriculum?
 
I think it is. I can't speculate on the curriculum at other institutions. Jerry Gollub wrote a very cogent article about this:

Physics Today / Volume 61 / Issue 10 / REFERENCE FRAME
Physics Today - October 2008
Teaching about fluids
 
That was quite an interesting article! In that case, is a "special topics" class the only point in my education that I might learn about fluids? At my school, several other engineering courses are listed as prerequisites to Undergraduate Fluid Mechanics. Even my high school physics teacher, who has a Master's degree in physics, admitted that most of what he knows about fluids he learned in high school several decades ago.

Another quick question I have is, if we don't have a separate fluids class, at what point in our education do we learn about concepts such as Reynolds numbers? How much are we expected to just learn on our own?
 
Indeed, most of the universities close to home don't even offer fluid mechanics for Physics Major (except Bernouilli's equation).

http://www.phys.uu.nl/~thooft/theorist.html recommends to study some fluid dynamics, so I guess it is important for a Physics Major (notice that he lists this subject in the beginnig of the list, so it's reasonable to assume universities should offer some courses about it. Also, I've read some books about it (never got very deep, though) and it seems to require vectors (and div, grads, curls), tensors and diff equations as math requirements. So I don't see a reason for not offering courses about it for undergraduates.
 
My school doesn't offer fluid dynamics in the physics department either. I'm sure there are courses in the engineering school. I guess the demand wouldn't be high enough for a straight physics course, but I'm kinda surprised it isn't cross listed or something.
 
There really is a need for a continuum mechanics/condensed matter class. Such a class would include fluid mechanics and statistical mechanics, but be very broadly applicable. As it stands, 200/300-level undergraduate mechanics classes are primarily an introduction to quantum mechanics.

Part of the difficulty is the lack of a good text, but this could change given the current popularity of 'soft matter' and biophysics books.
