Acoustic Radiation from Transducer in Semi-infinite Fluid Medium

Abstract

Acoustic pressure pattern due to a vibrating axisymmetric body in a semi-infinite fluid medium is calculated using the results of FIST program in conjunction with the method of images developed in the analysis. Far field and near field acoustic pressure patterns are calculated for a cylindrical transducer vibrating in a semi-infinite fluid medium. The method of images is developed to calculate the acoustic pressure in .semi-infinite fluid using the results ot FIST program. FIST program calculates the radiated and scattered acoustic pressure due to an axisymmetric body in an infinite fluid medium.
