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.
