Development of a mechanical mixing system of sensible heat storage equipment for a beam down solar concentrator

Nihon Kikai Gakkai ronbunshu, 2016
One of the merits of a solar thermal utility is that the cost of heat storage is lower than that of an electrical battery. Furthermore, a power generation system using solar thermal energy with heat storage equipment is capable of stabilizing its output.

Assessment of Performance Enhancement Potential of a High-Temperature Parabolic Trough Collector System Combining the Optimized IR-Reflectors

Applied Sciences, 2020
Heat collecting elements (HCEs) are the core components in the parabolic trough collector (PTC) system because photothermal conversion of the whole system occurs in the HCEs.

Effect of charging of phase change material in vertical and horizontal rectangular enclosures in a concentrated solar receiver

Case Studies in Thermal Engineering, 2020
The charging of phase change material (PCM) in a concentrated solar receiver is experimentally carried out in a parabolic dish collector. Rectangular PCM filled enclosures of 30 mm width in the solar receiver are investigated to study the effect of ...

3D-Printed Solar Cavity Receiver for Heating Pressurized Air – A Preliminary Evaluation

SolarPACES Conference Proceedings
High-temperature solar receivers experience non-uniform solar flux, which induces thermal stress in the receiver tubes. This stress is more pronounced in gas solar receivers due to the lower thermal conductivity of gases.
