Ultrasonic Cavitation in Water (1000 Watts Ultrasonic Homogenizer)

20kHz, ordinary city water at 20degC, ambient pressure, the pipe is approx. 140mm in diameter

The basic law of thermodynamics applies: All power is finally converted into heat. Nothing is lost. In this case it is 1000 W of which 85% are mechanical output at the sonotrode. Given a volume of approx. 1 gallon, this will heat the water at approx. 0.2K/sec.

Nice job.

for this setup approx. 25 micron (peak-peak). The amplitude can be changed by means of different booster horns and electronically at the front panel. Therefore, amplitudes from 3 to over 170µm are possible using the UIP1000.

The cavitational impact can be used to reduce the particle size of materials, such as nanomaterial agglomerates or pigments.

That would make one hell of a desktop version of the lava lamp. "Hey jim, check this out!" BZZZZZZZZZZ Id buy one, um, how much did that thingy cost?

Breaking down simple industrial wastes. Those bubbles have huge pressures and temperatures despite their size.

what exactly am i seeing?

Look better than a lava-lamp

what is inside a cavity?

LOL

Diagnostic ultrasound has been proven for the last 50 years to have NO bioeffects...

but steam implies the water has 'boiled' ultrasound does not heat the water - think back to the last time you had ultrasound at the dentist. so how can steam be inside the cavity? i think it must be something akin to a vacuum.

what's cavitation?i'm not english.

Actually I have an ultrasonic mister Im foolin with, and I made a container too small and melted the the top of the plastic straight through., Then dumb me stuck my finger in the stream and nearly burnt my finger, IN WATER!!!

Ultrasonic Cavitation is the creation of microscopic bubbles within water by use of high frequency sound waves. (Making the bubbles is cavitation.) What this is demonstrating is that, when these microscopic bubbles collapse, there is a luminous energy release. Thus the Tesla-esque light banding.

Awesome, looks like a real fire!

Think of Cavitation as where water is ripped apart by a vacuum with such force that some of it forms a gas bubble, or even a lot of gas bubbles, in the vacuum left behind. Cavitation is often seen in the wake of boat propellers as they spin fast through the water.

is this what happen in big diesel engines? i have seen the cylinder walls on coolant side full of tiny holes.(if you use the wrong coolant)

The water molecule can be dissociated with RF energy at low power. Just vibrate the water moecule at its resonant frequency.

That would be "boiling" -- this is different, it's Sonoluminescence. Look it up on google.

I'm pretty sure this isn't Sonoluminescence, rather like an ultrasonic humidifier, it vaporizes the water. On the same path, but not there yet. Make a torpedo that creates cavities of air around it to reduce friction :) .

I was part of a group that created a hull for a racing sloop that had a shape near the bow that would grab air from the waves that was caused by some turbulence, and the air reduced drag along the hull that with laminar flow would slow down the boat through the water. Air bubbles do reduce the drag by eliminating or reducing laminar flow and associated drag. Kind of like making the hull "stall" in the fluid. Less drag when you need it.

If you touch that, would your hand explode?

@broli123 lmao

...for an even CLOSER shave! ;P

It's also used to clean medical equipment and other small mechanical parts. The part is placed in a water bath and blasted with ultrasound. The Ultrasound cause cavitates the water on the surface of the part breaking away debris.

Ez FANTASZTIKUS ! Hálásan Köszönöm !
