摘　　要：以太阳能Kalina循环为研究背景,搭建太阳能光热光伏联合应用实验平台;借助单管太阳能热水器,通过实验和数值模拟的方法,对太阳能真空管热性能进行分析与测试;利用场协同原理,对单管太阳能热水器温度场和速度场进行可视化分析。研究表明:建立的二维数值计算模型,能准确反映同一条件下,全玻璃真空管太阳能热水器的变化趋势;真空管内加装导流板后,场协同性最高;最终确定加装反光板和导流板的Φ58 mm×1800 mm太阳能真空管为最佳选择。The joint application test bench for solar-thermal photovoltaic was set up to study solar Kalina cycle.The a-nalysis and testing of thermal performance on solar evacuated tube was carried out with methods of experimental and nu-merical simulation through the experiment platform of single tube solar water heater.The temperature and velocity field of single tube solar water heater were visible analyzed with field synergy principle.The study showed that the two di-mensional numerical calculation model could accurately reflect the trend of all-glass evacuated tube solar water heater in the same conditions and the coefficient of field synergy on evacuated tube which was equipped with guide plate was su-perior to other structures.It was finally confirmed that the Φ58 mm ＆#215;1 800 mm of solar evacuated tube equipped with reflector and guide plate was the best choice.
