Elliptical tubes receivers’ efficiency analysis in solar power towers

AIP Conference Proceedings, 2019
The high costs of the heliostat field, as well as the issues related with the receiver operation in solar power towers are some of the main reasons to study different tube geometry shapes for the receiver. The new geometries intend to improve its thermal efficiency and increase its lifetime, such as the elliptical tubes presented in this research.
