This work extends modelling of high prequency electric-acoustic transducers beyong current limiting approxilations, which is of interest to such applications as ultrasonic imaging, testing, tomography etc. / Thesis (PhD)--University of South Australia, 2001.

This work extends modelling of high frequency electric-acoustic transducers beyond current limiting approximations, which is of interest to such applications as ultrasonic imaging, testing, tomography etc. The developed methodology includes transient modelling of the acoustic potential field with dynamic Green?s functions and linear formulation of wave propagation in the moving reference frame. A finite difference model is determined to achieve fast numerical implementation. Developed is also experimental methodology for impulse response measurements, offering modifications of the inverse Wiener filter and introducing novel transducer equalisation increasing signal bandwidth. / thesis (PhD)--University of South Australia, 2001.

The principle of operation of a novel rotating disk ultrasonic intensity meter is studied. Its characteristics are explained by a competition between acoustic radiation pressure and viscous drag on the disk. Acoustic streaming does not play a significant role in the operation of this meter as it is now configured. Experiments are described which were done to find the optimum dimensions and position for a nylon disk. In this optimum configuration, the rotation rate of the disk is related to the ultrasonic intensity by a power law. This relationship is theoretically predicted and found to hold as the ultrasonic intensity varies by a factor of at least ten. / Science, Faculty of / Physics and Astronomy, Department of / Graduate
