Air Flow Observation: Wind Instruments

Click For Summary
The discussion centers on the desire to visualize air flow through wind instruments, specifically aiming to see streamlines rather than just measure velocities or pressures. Participants express skepticism about achieving clear streamlines due to potential turbulence, suggesting that observing standing waves might be more feasible. A clear replica of the instrument would be necessary for effective visualization. The original poster is also seeking recommendations for facilities in the New York area capable of conducting such experiments and has conducted preliminary searches without success. The conversation emphasizes the need for specialized equipment and expertise in aerodynamics to achieve the desired observations.

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

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?
 

Thread 'Is this a coincidence?... (distances between planets)'

I'm not a student or graduate in Astrophysics.. Wish i were though... I was playing with distances between planets... I found that Mars, Ceres, Jupiter and Saturn have somthing in common... They are in a kind of ratio with another.. They all got a difference about 1,84 to 1,88x the distance from the previous planet, sub-planet. On average 1,845x. I thought this can be coincidential. So i took the big moons of Jupiter and Saturn to do the same thing jupiter; Io, Europa and Ganymede have a...
