Design And Numerical Study Of A Highly Efficient Ocean Thermal Energy Conversion System

This paper summarized current situation of domestic and foreign development of ocean thermal energy conversion and put forward the important and difficult point of the research.What is more,the research analyses the design and performance of the OTEC system.The results of the research mainly include the following aspects:1.In this paper,a mathematical model of the ocean thermal energy generation cycle and the heat exchanger is established.Five different working fluids are chosen in this work,the loop output power and the ratio of the heat exchange area is used as the target parameter.Further more,this paper used MATLAB software to simulate different refrigerants OTEC system and get the maximum target parameters which can be achieved,and then identified the cycle working fluid of the circulation sysytem in the article.2.In this paper,a new type of the ocean thermal energy generation system is designed,and the mathematical model is established.According to the relevant data,cycle initial parameters were settled and the cycle thermal efficiency was calculated.This paper analyzed thermal efficiency and advantages and disadvantages by comparing thermal efficiency among Rankine cycle,Uehara OTEC system and reheat cycle system in the same original situation.3.This paper selected important means of the reheat cycle system.4.In this paper,a mathematical model of reheat cycle system is established,the process is to study the variation of two target parameters and determine the best system operating when the target parameters correspond to the maximum,the method is using matlab software to simulate the reheat cycle system.
