RAYTRACE FOR COMPOUND PARABOLIC CONCENTRATOR

This communication deals with the raytrace of tubular absorber of the compound parabolic concentrator. In order to investigate the location of the hot spots on the absorber, a raytrace was needed. There were different techniques to achieve an accurate raytrace. One of the technique was adopted is AutoCAD(R). The analysis was carried out and applied to a CPC with an acceptance angle of 10 degrees and a concentration ratio of x4.0. The objective was threefold Firstly, it was necessary to calculate the profile of the CPC and the tubular absorber. Secondly, it was necessary to analyse the distribution of intensity around the circumference of the tubular absorber, Finally, to analyse the phenomena of the rays inside the CPC for different incident angle.
