I need some help modeling water in a normal modes analysis. Water is the
"load" placed on my ultrasonic transducer. I solve for the normal modes of
the transducer without a problem, but now I would like to see the effect of
submurging the ultrasonic probe into water (both the effect on the
transducer = damping, and the effect on the water = acoustic intensity
field). Is there a way to do this with FEA (I only have access to the
I-DEAS software by SDRC)?
I'm working in the 15-70 khz range. I've tried using plexiglass/acrylic to
model the water, since it has approximately the same speed of sound as
water. The results have not correlated well with what is observable to the
eye. Any suggestions?
