Abstract:
The conditions that can create longitudinal resonance in the rectangular sonochemical reactor are studied. Based on the basic theory of three-dimensional wave equation, the equations of longitudinal pressure distribution are derived and simulated by Matlab. Our results show that the total sound pressure amplitude distribution is superposed by the normal sound wave and the higher vibration in-phase. When the liquid depth take an odd multiple of quarter wavelength, the effects of the higher vibration in-phase on the total sound pressure amplitude can be ignored.When four conditions are satisfied, the sound field distribution can create longitudinal resonance, which is similar to the standing wave formed by the single plane wave.
