The development of “Transparent Ocean”needs to provide a sustainable power supply for the oceangoing detection sensor. The principle of oscillating water column (OWC) power generation based on piezoelectric effect is that the wave energy can drive the deformation of piezoelectric functional material to realize the energy conversion, and the system structure is simple and stable.Based on the linear wave theory, the OWC twodimensional numerical wave tank was established. The results of the computational fluid dynamics (CFD) analysis showed that the wave was stable and the air pressure formed by the wave in the gas chamber presented a certain periodicity in the time domain. The data was fitted to a sinusoidal curve.The parametric design language (APDL) function of ANSYS software system is applied to develop the simulation model of airdriven piezoelectric material deformation output energy and analyze the characteristics of voltage variation.
