CIRCE2/DEKGEN2: A software package for facilitated optical analysis of 3-D distributed solar energy concentrators
CIRCE2 is a cone-optics computer code for determining the flux distribution and total incident power upon a receiver, given concentrator and receiver geometries, sunshape (angular distribution of incident rays from the sun-disk), and concentrator imperfections such as surface roughness and random deviation in slope. Statistical methods are used to evaluate the directional distribution of reflected rays from any given point on the concentrator, whence the contribution to any point on the target can be obtained. DEKGEN2 is an interactive preprocessor which facilitates specification of geometry, sun models, and error distributions. The CIRCE2/DEKGEN2 package equips solar energy engineers with a quick, user-friendly design and analysis tool for study/optimization of dish-type distributed receiver systems. The package exhibits convenient features for analysis of conventional'' concentrators, and has the generality required to investigate features are the ability to model dish or faceted concentrators and stretched-membrane reflectors, and to analyze 3-D flux distributions on internal or external receivers with 3-D geometries. Facets of rectangular, triangular, or circular projected shape, with profiles of parabolic, spherical, flat, or custom curvature can be handled. Provisions for shading, blocking, and aperture specification are also included. This paper outlines the features and capabilities of the new package, as well as the theory and numerical models employed in CIRCE2. 20 refs.
