Abstract
A tubular resonator is coupled coaxially to a half wavelength extensional resonator at a nodal region of the vibratory motion in a direction parallel to the longitudinal axis of the extensional resonator. The frequency of the vibratory motion is in the sonic or ultrasonic frequency range, typically in the range from 1 kHz to 100 kHz. The radially directed vibratory motion at the nodal region of the extensional resonator is coupled to the tubular resonator and is converted by the tubular resonator into radial flexural vibratory motion which motion travels along the wall of the tubular resonator in a direction parallel to the longitudinal axis. A fluid within the flexural resonator thus is subjected to intense vibratory energy.
