Computational Fluid Dynamics-Based Programming of Mechanical Power Generation Applications

Abstract

Electricity has a vital impact on human production and life, and energy storage systems are regarded as an important part of the "generation -transmission -distributionuse -storage" process. Mechanical elastic energy storage technology is a new type of energy storage technology recently proposed, which uses mechanical vortex spring as the energy storage medium and permanent magnet synchronous motor as the actuator to achieve energy storage and power generation. The aim of this paper is to investigate the design of a mechanical power generation application based on computational fluid dynamics. In this paper, a mechanical rectifier wave energy generation device is designed and the main work is as follows: the general structure of the device is designed, which mainly consists of three parts: the energy take-off mechanism (Power take-off, PTO for short), the float and the generator. The design of the structural parameters of the magnetically coupled force transfer system is completed according to the magnitude of the PTO force applied to the system. Based on the simulation model of the device, the effect of damping on the performance of the PTO system is analysed, and the input and output powers under different load resistance conditions are obtained to verify the optimal damping theory. The effect of wave period on the input-output power is obtained by varying the wave conditions.
