    Abstract
  • Ocean thermal energy power supply is an effective technique to increase the duration and range of underwater gliders. The optimization of the energy transfer path and improvement of the energy conversion efficiency are crucial for improving the operation of underwater gliders. Based on the energy conversion mechanism and loss mechanism of the mechanical energy-electric energy conversion process in the ocean thermal energy power supply system of underwater gliders, this study establishes the parametric energy balance equation, mechanical energy-electric energy conversion model, and conversion efficiency calculation equation of the hydraulic motor and generator and other key devices as well as performs an efficiency analysis of the energy conversion process. The relative error in the conversion efficiency of pressure-kinetic energy and kinetic-electric energy conversions, when comparing the results of the platform test and the model simulation, are 6.37% and 5.12%, respectively. The accuracy of the model is therefore verified, as these relative errors are small. As a result, the optimal design and prototyping of the ocean thermal energy power supply are performed. In the sea trial, the test prototype can harvest 6 701 J of electrical energy, and the energy conversion efficiency of the pressure-electric energy conversion process can reach 38.86%, validating the accuracy and effectiveness of the proposed model.
