Abstract:
Radiation flux of focal plane plays a very important role of efficiency in a parabolic dish solar system. This paper aims to present the distribution of radiation flux in focal plane for every incident solar irradiation. Monte Carlo ray tracing method is applied and coupled with the measuring value of incident solar irradiation in Harbin City hourly. The results show that radiation flux in focal plane remains unchanged for different radius from 0 mm to 15 mm, and gradually decreases for different radius from 15 mm to 20 mm. And the results also show that the influence of incident solar irradiation on radiation flux in focal plane is very great, and the highest radiation flux is 218 W／mm2 when incident solar irradiation value is 1100 W／m2
Key words: monte carlo receiver focal plane radiation flux
