抛物跟踪式太阳高温集热器的研究

THE OPTICAL ANALYSIS AND HEAT TRANSFER OF PARABOLIC SOLAR COLLECTOR

对单轴跟踪太阳聚集系统 ( PTC)进行了光学分析。对集热管内流体的混合对流 (强迫对流加自然对流 )和传热过程进行了探讨。理论模拟结果与实验结果吻合较好 ,两者间的最大偏差小于8%。

A numerical simulation has been conducted for the PTC collector The results of numerical simulation are well accord with the experiment ones The computer program can calculate the transient heat flux distribution of PTC reflector in any local time and any latitude automatically
