The Inner World of a Collapsing Bubble

[@rinner2801]

The observed shockwaves are especially impressive.

Here because of the Titan implosion but reminded why Fluid Dynamics was one of my favorite classes in undergrad

[@astrogirl1usa]

Wow, this is really cool to watch!

[@kenzietownsend6644]

Wow. Learning about ultrasonic cleaners. I was stuck on cavitation. Now, I can see it.

[@aaronvanalstine4287]

Bubbles collapse into violent shockwave-indicing events and stars collapse into black holes. It seems collapse is very common in nature.

Aaron VanAlstine it really is amazing how at least two things are unstable

[@kustomweb]

Looks like a microburst, I wonder if bubbles of moist air collapse against the stratosphere, creating the downward jet?

[@rinner2801]

Interesting idea, but I wonder considering macro vs. micro phenomena etc.

[@davidscott5903]

Do you have a version that is deeper, an not near the surface?

[@louf7178]

I would bet this keeps the bubble in viewing vicinity.

[@JeromeFryer]

Do we have an audio file of what this sounds like? Thanks

[@MarcosElMalo2]

It was inaudible.

[@JeromeFryer]

@@MarcosElMalo2 thank you

[@sivarao7126]

Can any one say why bubble initially expands and sudden compression???

[@MarcosElMalo2]

It’s at 0:08 “A cavitation bubble is created with a focused laser pulse in the vicinity of a free surface.” At 0:30 “Before reaching its minimum radius, the bubble is pierced by a free surface-induced jet.” (That is, the jet is induced by proximity to the free surface.)

@@MarcosElMalo2 Thank you so much sir, now it is clear

Ring bubbles into ring bubbles = minijets.
