Abstract
Such ultrasonic field parameters as near-field length and beam angle of divergence are studied for selected ultrasonic electrode shapes. Computer solution procedures to these problems employ a numerical solution technique of the exact governing equations for ultrasonic wave motion in a fluid. Emphasis is placed on examining the pressure magnitude variations along the centerline of a transducer in observing the near-field ripple as a function of piezoelectric element shape. Useful formulas for near-field calculations are discussed. Typical transducer shapes include cylindrical, square, rectangular, annular and star shaped. The effects of various ultrasonic response pulse shapes are also studied along with several off-axis spatial pressure profiles. Practical applications of the work are also outlined.
