Abstract: | The Monte Carlo ray-tracing method is applied and coupled with optical properties to predict the radiation performance of
solar concentrator/cavity receiver systems. Several different cavity geometries are compared on the radiation performance.
A flux density distribution measurement system for dish parabolic concentrators is developed. The contours of the flux distribution
for target placements at different distances from the dish vertex of a solar concentrator are taken by using an indirect method
with a Lambert and a charge coupled device (CCD) camera. Further, the measured flux distributions are compared with a Monte
Carlo-predicted distribution. The results can be a valuable reference for the design and assemblage of the solar collector
system. |
