SUMMARY

This discussion centers on the concept of reversing the effects of a centrifuge, specifically exploring mechanisms that can force material toward the center of a circular area. Participants suggest that while a centrifuge typically pushes lighter materials outward, a funnel can effectively direct substances to the center. Additionally, high explosives and high-energy lasers are mentioned as potential methods for achieving similar effects in specific applications, such as nuclear ignition and fusion research.

PREREQUISITES
  • Understanding of centrifugal force and its applications.
  • Familiarity with high-energy physics concepts, including nuclear ignition.
  • Knowledge of laser technology and its use in fusion research.
  • Basic principles of fluid dynamics and material movement.
NEXT STEPS
  • Research the principles of centrifugal force and its applications in various fields.
  • Explore the mechanics of high-energy laser systems used in fusion research.
  • Investigate the role of funnels in material movement and their engineering applications.
  • Learn about the physics behind nuclear ignition and the use of high explosives in scientific research.
USEFUL FOR

Engineers, physicists, and researchers involved in material science, nuclear physics, and fluid dynamics will benefit from this discussion, particularly those exploring innovative methods for material manipulation.

Hey all, first post here on PF.

This might be a stupid question, but I haven't been able to find if there is a machine that does the opposite of a centrifuge, specifically forcing material into the center of a circle. Or if there is a force that is reproducible on a small scale that does this.

Again, sorry if this is silly, but I'm thinking of making something and this is kind of crucial!

Thanks!

Seems to me you could use a centrifuge that has capsules at the end of it. The heavier material is forced into the center bottom dome of the capsule.
 
I can think of two examples:
1) Using high explosives (ie Nuclear Bomb ignition)
2) Using high energy lasers to detonate the surface of a fuel pellet (ie Fusion research)

If you have a particular application in mind it might be easier to come up with something more practical?
 
It depends on how much stuff, how quickly, etc.

A funnel forces everything to the center of a "circle".

Dang, how'd we miss that one!? D'oh!:-p

EMF in a ring around the substance you want pushed to the center.

A centrifuge does it... The lighter material moves toward the center. ;-)
