中文摘要： 热电发电是21世纪三大最具潜力的发电技术之一。连续流体、同位素和烃燃料燃烧是热电发电的三种主要热源。连续流体热源多模块热电发电技术的关键科学问题即热特性和电特性相互耦合时的系统热量传递与热电转换机理尚未有效解决。本项目拟建立热特性和电特性相互耦合时的连续流体热源热电发电系统物理与数学模型，分析热电材料物性、热电单元尺寸、流体热源温度、流态、流速、流道几何特征等因素对热电转换功率及效率的影响，进而揭示系统热量传递与热电转换机理与规律。结合研究需要和工程应用特点，建立以连续流体为热源、多流体通道、多热电模块组成的热电发电实验平台，获得热源与冷源流场沿传热方向与流动方向温度分布数据、热电转换规律，对建立的理论模型加以验证和完善。本项目的研究成果可为热电发电技术在低品位余热回收领域的应用提供参考。

英文摘要： Thermoelectric power generation is one of the three most potential power generation technology in the 21st century. Continuous fluid, isotope and hydrocarbon fuel combustion are three main heat sources for thermoelectric power generation. The key scientific problems of the continuous fluid heat source multi-module thermoelectric power generation technology that the heat transfer and thermoelectric conversion mechanism of the system when thermal characteristics and electrical characteristics intercoulping has not been effectively resolved. This project intends to establish the physical and mathematical model of continuous fluid heat source thermoelectric power generation system when thermal characteristics and electrical characteristics intercoulping, analyze the effect of thermoelectric material physical properties, thermoelectric element size, fluid heat source temperature, flow pattern, flow rate, flow channel geometry characteristics and other factors on thermoelectric conversion power and efficiency, and then reveal heat transfer and thermoelectric conversion mechanism and laws. Combineing the characteristics of research needs and engineering applications, a thermoelectric power generation experiment platform will be established contains continuous fluid as the heat source, multi-fluid channel, multi-thermo
