AB  - In this paper, a numerical study of the radiation flux and temperature distribution of a parabolic dish receiver is carried out. The SOLTRACE code is used to predict the radiation flux distribution and the FLUENT software is used to study the temperature distribution. In a first step, the concentrated solar heat flux distribution is calculated using the SOLTRACE software The calculated heat flux distribution obtained is then used as wall heat flux boundary conditions for the receiver. In a second step of this study, the receiver’s thermal performance is optimized by a simulation using the commercial CFD code FLUENT. Different receiver configurations are studied in order to define the optimal configuration to obtain the best performance. The first is a cylindrical receiver with a tangential inlet located at the bottom and a normal concentric outlet located at its upper surface and the second is a spiral absorber of 19 turns with an inlet across its periphery and an outlet across the central spiral. The effect of the different inlet-outlet positions of the working fluid is carried out. Two positions are studied: the first position is characterized by an inlet through the periphery and an outlet through the central spiral and the second by an inlet through the central spiral and an outlet through the periphery. The thermal analysis has proven that the 19-turn spiral tube with an inlet through the periphery and an outlet through the central spiral is the best configuration that improves the efficiency of the solar receiver and the overall performance of the solar dish.
