Degassing of viscous liquids

Can anyone direct me to information regarding the use of ultrasonic vibration to migrate air voids from viscous liquids. I am submerging tubes in a water bath, filling the tubes with a viscous liquid and use mechanical vibration to migrate entrapped air from within the filled tubes before the liquid solidifies. I have had success with this process. I would like to pursue ultrasonic vibration to degass the viscous liquid before it solidifies.

Any and all information reqarding the use of ultrasonics to degass liquids would be greatly appreciated.

Re: Degassing of viscous liquids
We are using this method in water. It works very good. Only what you need is power ultrasound. We can deliver the necessary devices.

Ultrasonic wave can be used to cause motion in liquids in the direction of
the propagating wave. This phenomenon is called streaming and some people
is using it to make liquid pumps. Unfortunately, at the levels that this
phenomenon occurs cavitation can also occur which will lead to accumulation
of air bubbles. I am not in town right now so I don't have a good access
to my references but a good high power ultrasonics book will do it. One
example I can think of is the book by Ensminger.

Re: Degassing of viscous liquids
Why not run the fluid through a vaccum chamber to remove all gasses and moisture?
Procedure used for electrical HV transformers quite often.

Re: Degassing of viscous liquids
I am a phd student, strathclyde university,glasgow, working on continous degassing process of viscous fluid, we do have very big similarity in this area, in my study, the answer is more in the fluid itself, i wish to hear more about your study before i could give somethings beneficial.
