【摘要】 研究了场协同理论在太阳能热气流发电系统优化中的应用。太阳能热气流发电系统的内部优化受温度、速度等多种因素的影响，而协同角的大小可以反映流动与传热的综合影响，也对系统的优化起指导作用。从太阳能热气流发电系统模型关键区域的协同角、温度、速度和功率等方面进行了优化研究，结果表明，当底部导流结构为圆台型时，基准面速度和发电功率最大，速度场和温度场协同角小的区域越大，协同性较优，因此优选圆台型作为底部导流结构。更多还原

【Abstract】 The application of field synergy theory in optimization of the solar chimney power plant system is studied. Many factors such as temperature, velocity and other characteristics can be used to measure the optimization of the internals of solar chimney power plant system. The field synergy angle may be utilized to reflect the comprehensive influence of flow and heat transfer, and also plays a guiding role in the optimization of the system. The synergty angle, temperature, velocity and power of the key regions of solar chimney power plant system model are considered to optimize the structure. The results show that when the bottom diversion structure is circular truncated cone type, the reference-plane velocity and generation power are the largest, and the area with small synergy angle between velocity field and temperature field is larger, the synergy is better. Therefore, the circular truncated cone is selected as the bottom diversion structure.更多还原
