The main advantage of LFR systems is that their simple design of flat or flexibly bent mirrors and fixed receivers requires lower investment costs and offers a wide range of configurations. These advantages can offset the lower solar-to-heat efficiency, and LFR power plants represent an interesting alternative to parabolic trough power plants. In addition, Fresnel solar fields permit higher land use efficiency than any other type of solar fields. The considerable economic advantages of Fresnel collectors are principally related to their constructive simplicity. The main reason for this is the search for cheaper solar field solutions. Nevertheless, in the last decade LFR systems have aroused an increasing interest. For that reason CSP development efforts have concentrated on parabolic trough geometry. Parabolic troughs represent the optimal solution for achievable concentration ratio and achievable energy yield per aperture area and, hence, the best overall plant efficiency in line-focussing mirror systems. LFR plant is highly modular, ranging from a few hundred kW to several MW in size, and offers the lowest land occupancy compared to other CSP technologies.

Moreover, the Fluent code has been developed in order to conduct the CFD modeling at the absorber tube of the solar collector. The thermal evaluation is based on the energy assessments characterized by the differential equations of pure water with a flow mass rate equal to 0.015 kg sā1 and copper absorber tube temperature. The numerical simulation with a 1D modeling in transient mode was performed by using the finite difference method. Abstract: An experimental and numerical investigation of a small linear Fresnel for water heating application has been carried out in Blida, Algeria.
