Study on hydrodynamic characteristics of a New Type of Marine Energy Generator

Abstract: The offshore operating environment where marine power turbines are located is harsh, equipment is prone to failure and maintenance is difficult. Based on the three-dimensional potential flow theory and the ANSYS-AQWA software, the hydrodynamic characteristics of marine energy generating turbines under the combined action of wind, wave and current loads are studied, and the power generating turbines under working conditions and extreme working conditions are obtained. Motion response characteristics. The results show that the maximum value of the amplitude of the motion response of the floating body occurs when encountering the oblique wave and the transverse wave respectively; the amplitude of the motion response under the extreme conditions is 3-10 times that under the working conditions. The device has good hydrodynamic performance after cyclic modification, which can meet the practical engineering application. The calculation method proposed in this paper can be used as a check method for quickly predicting the hydrodynamic characteristics of the device, and meets the needs of the engineering design stage.
