Numerical Modeling of Light Sources with R-FEM Method in CFX Environment

摘要

Paper presents usage of the R-FEM method in the CFX environment. The RFEM method was used for modeling of special light sources and to compute lighting of surfaces from these sources with very good results. Basic description of the R-FEM method is described below. For modeling of the light sources in the CFX environment was used combination of the Finite Volume Method and the radiation method which are included with the CFX (The Discrete Transfer Model and The Monte Carlo Model). Numerical results are presented by models with basic optical geometry (parabolic surface with light source placed in focus point and reflecting surfaces with different angular displacement). There are presented numerical results for mirrored reflecting surfaces and diffusion reflecting surfaces with different degrees of diffusion.
