Water Tunnel Testing (photos) Answered
I'm starting a new topic so I can edit it later with more content.
I went with some friends to a different lab section that was also playing with the tunnel (my official turn is on Friday).
Things put in:
1. PVC tube -- to show detachment of a cylinder
2. Golf Ball -- to show how dimples create turbulence and keep flow attached longer
3. Tennis Ball -- to show how fuzz acts almost like golf ball dimples
4. Porsche 911
5. Atlantis Space Shuttle
6. Porsche 911-turbo (or possibly a 935 or 993 -- can't remember)
7. Chain Mail Cube -- wtf? why did someone make that?
8. Surf Board Fin
9. Optimus Prime
10. Unknown Porsche (I just can't remember what it was)
11. Batting Cage Ball
The pump was set to 3.55 inches per second. So for a 1/64 scale model (for the cars) - that's just under 13mph equivalence (in water).
My camera had a low battery -- so the shutter was slower than normal. I'll get fresh batteries and a tripod on Friday I'll have some better pictures (hopefully).
As for what I'm bringing in... Still don't know -- but I think I am going to do a comparison of apples and oranges :P
Videos of the 911, 911turbo, unknown porsche and of the overall tunnel in operation ;)
Update November 3rd
1. Plastic Cone (with hole in top)
3. Eyeglass Case
4. Obligatory Altoids Tin
5. Plastic Water Bottle
6. Highlighter Cap
7. Reverse Gear from a manual gearbox (Nissan)
8. Pen Cap thing
9. Rubber Duck
10. Nerf Dart (velcro top)
11. Batman Shield (this was really cool)
12. Welded Plate
13. Golf Ball
14. Guitar Bar
15. Wing Foil
Again, it was set to 3.55 inches per second. I couldn't find an orange on campus (weird considering I'm in central Florida :P). So I'd say an orange is kinda like a golf ball :P
The Bat Shield video is very cool - if you watch just one of them, make it the bat shield ;)
