SUMMARY

The discussion focuses on the interaction between two vortexes created by turbines or fans positioned to face each other. In Experiment A, two turbines spin in a mirror fashion, creating mirror vortexes that attract water towards them. In Experiment B, the turbines spin in opposite directions, generating counter-rotating vortexes that do not attract each other. The participants propose that the results of these experiments could reveal insights into pressure dynamics and vortex behavior, potentially applicable to larger gravitational bodies like black holes.

PREREQUISITES
  • Understanding of vortex dynamics and fluid mechanics
  • Familiarity with the Venturi effect
  • Basic knowledge of gravitational physics and frame dragging
  • Experience with experimental design and setup
NEXT STEPS
  • Research the principles of vortex formation in fluid dynamics
  • Explore the Venturi effect and its applications in fluid systems
  • Study frame dragging in general relativity and its implications for rotating black holes
  • Investigate experimental setups for visualizing vortex interactions using colored fluids
USEFUL FOR

Physicists, fluid dynamicists, and engineers interested in vortex behavior, gravitational interactions, and experimental physics will benefit from this discussion.

Just a question I have in my mind if someone would be kind to answer.

What happens if you have two vortexes with their sucking mouths pointing at each other and the two vortexes meet where a) they are spinning mirror fashion b) they are spinning counter-fashion?
 
Physics news on Phys.org
Pls, describe your proposed experiment with more detail... Imagine what kind of configuration would give the two vortices in the positions you want.
 
Okay. Umm...

Two turbines in the water facing each other spinning with a sucking motion towards each other. In experiment A they spin mirror fashion with blades tilted oppositely so that they both still suck. In experiment B they spin counter directional but with blades likewise tilted so that they both still suck. Throw in a little dribble of food colouring to allow the swirls to be visible.

Experiment A creates mirror vortexes and experiment B creates vortexes that are spinning the opposite direction to each other. Yet both are still sucking water (and therefore anything in the water) towards themselves.

Any idea what the results would be on the water in between and on the pressure between the turbines towards (or skew with) to each other?

Similar thing could be done with fans I guess? You would have to buy two identical fans and another fan that is opposite to them left-to-right. I guess the fans would blow instead of suck unless you stuck them back to back.
 
Hm... so, they're initially separated. OK, then, Venturi effect might make them feel attracted in the mirror-image case. Then, they would make a single vortex tube, I guess... In the other case, they would feel no attraction, and if you force them into contact, they will tend to cancel out...
 
Cool thanks.

I wonder then if you spun two large gravitational bodies fast (gravity being a sucker of course) and then (taking into account the frame dragging effect of spinning gravitational bodies in GR) if you pointed the poles at each other, whether this would produce a similar complementary or canceling effect too when you have complementing or opposing frame dragging occurring?

Possible?
 
So, kind of, two black holes with accretion disks facing each other... Dunno... Make another post with it :)
 
Yeah we'd need something big wouldn't we to see much?

Time for sleep. I'll look again tomorrow hopefully.
