文摘

Monte Carlo radiative transfer simulation developed for a CPC solar reactor. Characteristic matrix method describes in detail the optics of catalyst films. Multi-tubular array of glass supporting surfaces for the catalyst is simulated. Radiation absorption by the reactor improved by increased absorber tube radius. Film thickness has to be kept inversely proportional to tube radius.
