Design and Optimisation OF 2-D Static Solar Concentrator

الملخص

A non-imaging solar concentrator system of reflecting surfaces redirects the solar radiation from the source to target (receiver). This work is focused on a 2-D elliptical hyperboloid geometric design of static solar collectors, though many design concepts and procedures for 2-D static solar collector is discussed in this paper. Based on the general equation for a solar concentrator, parameters vary slightly to determine the optical efficiency. 2-D MATLAB code is written to obtain the different shapes of the concentrator. The results
of 2-D hyperboloid concentrator (2-DHC) has been reported. The optical efficiency, effective concentration ratio, receiver major axis and concentrator height have been investigated through ray trace analysis. The optimisation of the concentrator profile and geometry is also carried out, based on the geometrical concentration ratio. The maximum optical efficiency is found to be 51% and the maximum acceptance angle of ±60° was achieved
