Piezoelectric transducer for liquids

Muhammad Mohsin Rehman

Please login with a confirmed email address before reporting spam

Hi all,

I am using COMSOL to model a piezoelectric transducer directly coupled with liquid (oil or water) and using the tutorial provided in COMSOL website in this aspect. I am just defining one boundary of piezoelectric material as oscillating boundary (applied with voltage) and the other one grounded but am not sure about the results. Can any one answer a few queries regarding this?

- Are there any reflections of ultrasonic waves from liquid when placed in this way?
- How can I check the impedance matching characteristics of the piezoelectric especially the acoustic impedance?
- Can I change the phase or beam angle of piezoelectric transducer? If so, how?
- After having a look on the attached image, can some one explain the result and why I am getting this?

Many thanks in advance for any of your help.

Hiii,

Can you attach the .mph file? It is very difficult to say answer from the image.

Thanx.

Hi,
Have you solved your problem? I have the same problem with you. Could you send me your model? I'd appreciate it.
