Mathematical Modeling and Optimization of a Parabolic Trough Concentrator for the Improvement of Collection Efficiency

Arun Kumar; S.K.Shukla

Abstract

In the present scenario of a huge energy demand, dependency on fossil fuels only, certainly creates crisis in future especially for developing country. Although renewable resources of energy like solar energy is being utilized on a broad scale now a days but the problem comes in law and economy i.e. social and acceptability. Economy is the main criteria in modern era of huge energy requirement and its social acceptability. Keeping these points in view, a concentrating unit i.e. parabolic trough concentrator has been designed in such a way that it can produce optimum power. An empirical relation has been established between receiver area and aperture area and it was found that concentration ratio, CR is 81.69.Ratio of the height of the parabola to the focal length () is 1.7 and between aperture diameter, D and focal length, f is D = 5.21 f. The value of rim angle corresponding to the optimum value of concentration ratio 81.69 is 74.97°. These optimized values which have been calculated in this paper, is able to achieve the maximum collection efficiency of a parabolic trough concentrator.
