EFFECTS OF MATERIAL SELECTION ON THE RADIATION FLUX OF A TUBE RECEIVER IN A DISH SOLAR SYSTEM
摘要
A solar receiver plays an important role in the performance of a solar dish electric generator. Its radiation flux can directly affect the efficiency of the whole solar energy system. In this article, the distribution of radiation flux inside a tube receiver made of five materials is simulated successfully using a Monte Carlo ray-tracing method. The mathematical model of the radiation flux based on a Monte Carlo ray-tracing method is developed in this article, and the computer code for the method is written in FORTRAN language in-house. It is evident that the radiation flux distribution inside the tube receiver is highly nonuniform. The effects of five materials on the radiation flux inside the tube receiver have been investigated, among which steel with a black paint achieves the maximum radiation flux. The results show that the radiation flux is almost negligible up to the receiver height of 80 mm, then increases sharply to its maximum at about 130 mm, and finally decreases at the height of 260 mm. The results also indicate that the maximum radiation flux occurs at the position of 130 mm for all five materials.
