Abstract
In this paper,the performance of parabolic solar collector with three segmental rings has been investigated numerically. The effect of three segmental rings size on the thermal efficiency of receiver tube has been studied. The working fluid is syltherm 800 and the analysis is carried out based on renormalization-group (RNG) k–? turbulent mode. This numerical simulation is implemented for a constant distance between three segmental rings, the results show that use of three segmental rings in tubular solar receiver enhances the Nusselt number and system performance. By decreasing the inner diameter of three segmental rings, the Nusselt number increases, but with considering the pressure loss, thermal performance decreases.
