ABSTRACT -- puter Simulation Program for Visual & Numerical Analysis of Solar Concentrators (VNASC) and specific visualization technique for PC simulation and CAD of solar concentrating systems are described. The program has two code versions (FORTRAN and C++). It visualizes a concentrating process and takes into account geometrical factors and errors, including Gauss errors of reflecting surfaces, facets' alignment errors, and sun-tracking errors. The VNASC program is developed as a specific library of functions and subroutines that are supplied by the flexible main program anizes the graphical user interface in a convenient menu system. So the source code of the main program could be very promptly adjusted puter simulation of any particular solar concentrating system.
1. INTRODUCTION
Computer calculations of solar concentrators mostly are devoted to investigation of the final output characteristic of a concentrating system, the concentrated flux density's distribution on a receiver surface. Since the distribution is a result of an interaction of all kinds of geometrical features of a solar concentrator, it is very difficult to separate the contribution of any one certain factor from this “mixture”. The VNASC program also provides calculations of flux density distributions. But in addition, it allows us to analyze how the distribution is configured by the optical system’s geometry. The program uses specific scientific visualization methods that are developed just for these purposes.
The concentrated flux density in any point on a receiver surface is equal to an integral of the i
