Abstract
In this paper, the parabolic trough collector (PTC) is numerically examined with the aim to choose the most appropriate receiver tube configuration. In order to carry out this study, the adopted method comprises two major steps. In the first step, the concentrated solar heat flux densities in a focal zone are calculated by SOLTRACE software. In the second step, computational fluid dynamics (CFD) simulations are performed to analyze and optimize the thermal performance of the tube receiver. The calculated heat flux densities by the SOLTRACE software are used as heat flux wall boundary conditions for the receiver tube. The effect of the absorber tube cross section shape on the performance of the PTC system is analyzed. Triangular-, rectangular-, and circular-shaped tubes are tested and results are compared.
