Solar energy is the most widely available and used kind of renewable energy discovered so far.Solar thermal energy is an indispensable way to realize a large-scale and low-cost utilization of this energy.In order to understand more about optimizing devices using this technology,we will study in this paper an innovated Linear Fresnel solar Collector.First,this paper focuses on the introduction of this mechanical proposed solution which combines three movement.Technological solutions are proposed and discussed in order to optimize the system in every ways.This innovated system proposes an opening about the future of LFC's technology.To complete this study,an optical analysis is carried out,where geometrical parameters,as well as other design parameters such as optical properties,are analysed.The theoretical study of the optical performance is completed by accomplishing simulations,using Monte Carlo simulation method.The factors which affect the optical performance are analysed and optimized.Thus,the optimum optical efficiency and can reach up to 80.2% for a certain arrangement which is detailed here.Then,the energy balance equations are settled down in order to analyse where this collector is lacking thermal efficiency and thus can be optimized.This theoretical analyse is done using the heat transfer laws.In order to know exactly the values of states variables in any spatial point of our system and for different working conditions,thermal performances are analysed and predicted by employing the Computational Fluid Dynamics method.As a result,the best combination of working parameters is determined to optimize the functioning of the system.Finally,the heat loss of the system is plotted in order to observe the thermal performance for different working temperatures.
