摘要
通过搭建斜坡太阳能热气流发电实验台,在室内对系统进行了稳定状态下的实验研究。在改变烟囱高度和改变热流密度两种工况下进行实验,研究两者对流体速度与温度的影响。实验研究表明,集热棚内部流体的温度为非线性分布;随烟囱高度升高,集热棚出口风速增大,流体温度降低;随热流密度增大,集热棚出口风速及温度均大幅度增大。
Slope chimney experimental system was designed and built for the study on the system fluid temperature and speed distribution inside the solar collector.Influence of the chimney height and heat flux was researched by experiment.The temperature distribution inside the collector was non-linear.The speed of fluid was increased and the temperature of the fluid was reduced when raise the height of chimney.The speed and temperature of the fluid were increased when enhance the heat flux.
