Numerical analysis of the impact of geometric variables on the optical efficiency of a solar dish

In this study, the Monte Carlo method was applied to estimate the concentrated solar radiation along the perimeter of the receiver in a solar dish system. This approach aids in creating solar heat flux distributions for various solar system structures. The effect of several parameters is examined to determine the most efficient solar parabolic dish configuration.The effect of positioning the receiver at varying distances from the dish vertex has been simulated. Six different distances D are tested: $\mathrm{D}=1.8 \mathrm{~m}; \mathrm{D}=1.81 \mathrm{~m}; \mathrm{D}=1.82$; $\mathrm{D}=1.84 \mathrm{~m}; \mathrm{D}=1.85 \mathrm{~m}$ and $\mathrm{D}=1.86 \mathrm{~m}$, respectively. It has been demonstrated that the distribution of solar radiation rises as the receiver placement decreases.Furthermore, the influence of the solar receiver’s diameter on the concentrated flux distribution has been investigated. The parameter is studied in the following ranges: diameter of the receiver from 0.5 to 3 m. The findings indicate that the concentrated solar flux grows as the diameter of the receiver decreases.
