Published at Applied Thermal Engineering – Optimizing the configuration of external fins of solar receiver tubes for the solar parabolic trough collector

Abstract This paper aims to present a numerical study that aims to enhance the thermal efficiency of externally finned solar absorber tubes for use in the solar parabolic trough collector (SPTC). Compared to the internal finned tube, the external finned radiation absorber tube boasts an improved geometry and a simple and straightforward manufacturing process. This …

Published at Renewable Energy – Modelling of radiative and convective heat transfer in an open cavity volumetric receiver for a 50-MWth beam-down integrated receiver-storage concentrating solar thermal system

Abstract: This paper concerns solar-to-thermal energy conversion processes in an open cavity volumetric receiver for a 50-MWth integrated beam-down receiver-storage concentrating solar thermal system. A multiphysical model was developed in a COMSOL Multiphysics 6.1 environment. The model was validated against experimental and modelling data from the literature. The model incorporates specific solar irradiation profiles tailored …
