Abstract: A new method for the heliostat field optimization is presented. The method is intended for further performance improvement after initial layout with a standard heliostat field layout tool. During the field refinement, the ...

Abstract: A numerical model of the CentRec® receiver has been developed and validated using the measurement data collected during the experimental test campaign of the centrifugal particle system at the solar tower Jülich. The model ...

Abstract: An experimental and numerical modal analysis was performed on an 8 m2 Tshaped heliostat structure at different elevation angles. The experimental results were used to validate a finite element (FE) model by comparing natural ...

Abstract: The cost reduction potential of solar power towers (SPT) is an important issue concerning its market introduction. Raising the steam process temperature and pressure can lead to a cost reduction due to increased overall ...

Abstract: Increased receiver temperatures of solar tower power plants are proposed to decrease the plants levelized electricity costs (LEC) due to the utilization of supercritical steam power plants and thus higher overall plant ...

Abstract: Particle solar receivers promise economical and operational advantages compared to the molten salt-based solar receivers. In this study, an experiment is designed to observe the particle flow characteristics in the Centrifugal ...

Abstract: A novel concept of a particle receiver for hightemperature solar applications was developed and evaluated in the present work. The socalled Centrifugal Particle Receiver (CentRec) uses small bauxite particles as absorber, ...
