Sinopsis

A relatively low density of solar radiative flux on the Earth orbit or surface makes important the use of solar concentrators to develop high-temperature solar power plants (HTSPP). For the same reason the creation of high-power (MW-range) HTSPP necessitates the development of large-sized mirror concentrating systems (MCS), with stringent requirements for their shape and reflecting surface quality being met. While elaboration of such systems, one should develop sufficiently accurate and not too time-consuming computational tools to analyze the characteristics of MCS of different configurations. The latter enables one to choose the most suitable system for specific engineering problems. Experimental determination of the large-sized MSC is usually very problematic. Therefore, developing a mathematical model capable of estimating power characteristics of complex MCS taking into account the effects of operating conditions, design features, strains, roughness and possible surface defects is of particular interest. A statistical mathematical model of radiation heat transfer based on both the Monte Carlo and finite methods is developed in the present
