Abstract

This paper investigates the performance of concentrated solar parabolic trough by means of numerical analysis and experimental works. The study is carried out on two parabolic trough prototypes with different focal length of 12.5 cm and 20 cm. Test setup consists parabolic trough mirror, supported by aluminium structure. A geometric equation to optimize the shape of parabolic trough is presented. The validity of the concept is demonstrated by measurements in the laboratory. Results of focal and slope errors showed that the middle and top of the parabolic surface appears to be the best region for an effective reflection of rays. It is estimated that the parabolic length can be reduced by nearly 25% of the total surface area which allows for an optimization of the shape and dimension of parabolic trough concentrators.
