| Summary: | A verification study of ultrasound transmission numerical simulation results with experiment results
is presented in this paper. The work considers a model of a transformer tank which is filled with electro
insulating oil. In the experiment, performed under laboratory conditions, an ultrasound wave is generated
by a piezoelectric transducer that is fixed in the centre of the tank and measured by another transducer
mounted inside the tank at three distances: 10, 20 and 30 cm from the sound source. The transducer is able
to measure and generate acoustic waves in the ultrasound frequency band up to 1 MHz. The simulation
considers numerical calculation of acoustic pressure distribution inside the tank in which acoustic source
emits waves with frequency equal to 100 kHz. Verification analysis has confirmed consistency of the
numerically calculated values with the measurement results. |
