Deflection and stresses in solar central receivers [PDF]

Solar Energy, 2020
The aim of the design of central solar receivers is to withstand the high non-uniform solar-heat-flux and temperature during the solar-power-plant lifetime. This high non-uniform tube temperature causes high thermal stress, producing creep and fatigue damage.

Experimental Test Setup of an Airwall to Reduce the Convective Heat Loss in Solar Thermal Cavity Receivers

SolarPACES Conference Proceedings, 2023
An experimental setup is presented which allows to experimentally determine the thermal heat losses from a heated solar cavity  receiver with an airwall. The setup is a ‘near-full-scale’ replica of a receiver, which ensures that the characteristic fluid

Atmospheric Transmittance Model Validation for CSP Tower Plants

Remote Sensing, 2019
In yield analysis and plant design of concentrated solar power (CSP) tower plants, increased uncertainties are caused by the mostly unknown solar attenuation between the concentrating heliostat field and the receiver on top of the tower. This attenuation
