Abstract
Abstract In this paper, the effect of reflector width on the performance of Linear Fresnel Reflector Solar Concentrating System (LFRSCS) concepts with horizontal and vertical absorber is examined. The angular error correction and modeling is done using Gaussian distribution and its impact on the LFRSC system is analyzed. A theoretical model encompassing all the governing parameters is developed by taking into account the intricate phenomenal inter dependencies and influences of parameters on the designs output. The effect of different design parameters on the concentration ratio for both the systems is thoroughly investigated. The performance are evaluated based on the concentration ratio. The formulae being iterative in nature are solved computationally using programs written in MATLAB. Optimal design parameters are selected from the solutions which in turn minimizes the material and land requirements. The distribution of Local Concentration Ratio (LCR) on the surface of the horizontal and vertical absorber for both the designs is investigated using analytical technique. The corresponding average orientation error (in degrees) in Horizontal and Vertical designs are 4.6224 × 10 - 4 and 4.6375 × 10 - 5 respectively. The final observations are recorded and their outcome emphasizes that the horizontal absorber with varying width outperforms the system with vertical absorber with varying reflector width with angular error correction.
