Vortex question

[8/22, 21:29] Harish Ravi: So I wanted to come back to India and subscribe to resonance..

[8/22, 21:33] Harish Ravi: I did von Karman experiment in class 12 with powder on water..

[8/22, 21:34] Harish Ravi: Let's try the experiment soon

[8/22, 21:44] Harish Ravi: R=ul/viscosity

[8/22, 21:45] Harish Ravi: My question was how to derive this with dimensional analysis

[8/22, 22:04] Harish Ravi: Subbu and me thought of 3D turbulent flow visualization with leds.. the question was what's the parallel Karman spheres? Cylinders?

[8/23, 06:02] Harish Ravi: So is air Karman Vortex for 10 cm thick wing 1m (the wing length)? This is what I want to calculate

[8/23, 06:10] Harish Ravi: Same question for ceiling fan.. are there vortices

[8/23, 06:11] Harish Ravi: Let's calculate this week
