Air Flow Observation: Wind Instruments

Click For Summary

Discussion Overview

The discussion centers around observing air flow through wind instruments, with a focus on visualization techniques, potential experimental setups, and the search for suitable facilities in the New York area for conducting such tests.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Jeremy Bloom expresses interest in observing air flow through wind instruments and suggests a lab that tests aerodynamics of cars as a potential setting.
  • Some participants inquire about the specific visualization goals, questioning whether the focus is on measuring velocities or pressures, or visualizing streamlines.
  • One participant expresses skepticism about the possibility of obtaining clear streamlines, suggesting that the flow may be turbulent, but notes that standing waves might be observable.
  • There is a suggestion that a clear replica of the wind instrument would be necessary to visualize the flow effectively.
  • Participants are encouraged to search for existing resources or facilities that might assist in this endeavor, with links provided to relevant websites.

Areas of Agreement / Disagreement

Participants have not reached a consensus on the feasibility of visualizing streamlines in wind instruments, with differing opinions on the expected flow characteristics and the potential for observation.

Contextual Notes

There are limitations regarding the assumptions about flow behavior in wind instruments, and the discussion does not resolve the technical challenges of visualization or the availability of suitable facilities.

Who May Find This Useful

This discussion may be useful for individuals interested in experimental fluid dynamics, acoustics, or those seeking to explore visualization techniques in aerodynamics.

I would like a way to be able to observe the air flow through wind instruments. I was thinking a lab where the do tests on the aerodynamics of cars. any other ideas.

also does anyone know of a facility in the New York area that might be capable of such a technique. I would like to video tape the movement. I would also need to come to the lab twice in the period of a few months

thanks
Jeremy Bloom

What exactly are you hoping to visualize? Do you simply want to measure the velocities or pressures at certain points or do you hope to see streamlines flowing through the instrument?

Not measurements, visualizations: I'd like to see streamlines
 
Honestly, I don't think you'd get anything like a nice streamline. I'd suspect it would be a turbulent mess except possibly near the holes. You may be able to see the standing waves in the instrument though. That would be neat to see. That's just an off the cuff opinion though.

I can't say that I have seen wind instruments examined like this. You'd obviously have to make a replica out of a clear material so you could see the flow inside. After that it's pretty easy to introduce a flow and see what comes up.

Have you done any searches on Google, etc...for what you are looking for? I did a quick one and came up with this:

I just wanted to bump this to the top again. . . does anyone know of a lab that can do this?
