Ultrasonication of a pressurized liquid

I need to perform ultrasonic cleaning of a high pressure flow process (300 bar). I would like to do this by introducing a sonotrode directly into the system. I have a 200 W 20kHz generator with a long Ti alloy sonotrode. Is this possible? Does anyone have suggestions on how this can be done (or even better experience with pressurized systems)?

Hi Sosa,

Sorry for the long delay responding to this. I suspect this may be an application where physical limitations and engineering challenges may be more difficult than the ultrasonics. eg. you could insert the probe through a port in the chamber but with 300 bar internal pressure would this be practical? How would you seal it? How much force will you need to resist on the sonotrode?

I guess you've probably found this already, but if not one radically different approach you may want to investigate is to vibrate the pressure vessel itself - as MPI Ultrasonics did to develop cleaning in liquid CO2.
