In this study, the effect of using conical strip inserts on the thermal performance of
a parabolic trough collector is investigated. Reynolds number varies from 8,000 to
40,000. The results demonstrate that the Nusselt number is increased about 91.949%.
Furthermore, the effect of using conical strip inserts on friction factors is studied.
Performance evaluation is used for analyzing the benefits of this kind of turbulator.
The overall thermal hydraulic performance (PEC) is varied from 1.107 to 0.679.
