Hi Joe_Smith;
Fascinating !! .. I never knew this ! (I reckon their price of $US450 for the Couette Cell, and $US50 for the plans is a bit steep, though !)
I guess, in spite of its everyday occurrence around us, we probably never stop to contemplate the concepts behind pure laminar flows.
When I looked at the video, I was amazed. I was also reminded of that giant hexagonal feature on the north pole of Saturn.
One hypothesis proposed is that this feature may be due to laminar flows of the winds in that region .. and was demonstrated by the same notorious, perspex spinning bucket !!
Also makes one wonder whether the Great Red Spot of Jupiter, (etc) is held together by the same physics (ie: likely).
Thanks for your input. It really is a fascinating topic.
Cheers
