Abstract
A simple model is proposed to explain the generation of low-frequency oscillations of bubble plumes. the bubbly medium surrounded by water is considered as a waveguide {cylindrical plume [N. Q. Lu et al., IEEE J. Ocean. Eng. 15, 275–281 (1990)]}, with Bessel functions [Jm(•)] representing the oscillatory nature of the acoustic field inside the plume while modified Bessel functions [Km (•)] represent the evanescent field in the bubble-free water. the resonant frequencies of the plume have been calculated as a function of the void fraction. There is reasonable agreement between theoretically calculated frequencies and the experimentally observed acoustic signals. ‘.
