The abstracts & publications produced under the scope of the CAPTure project are available below:
- The challenge of solar powered combined cycles – Providing dispatchability and increasing efficiency by integrating the open volumetric air receiver technology. This work analyzes the performance potential of solar-only powered combined cycles, comparing the impact of two different solar receiver technologies (opaque-heat-exchanger-type vs. volumetric). December 23, 2019.
- Techno-Economic Optimization and Benchmarking of a Solar-Only Powered Combined Cycle with High-Temperature TES Upstream the Gas Turbine. This work presents a techno-economic parametric study of an innovative central receiver solar thermal power plant layout that applies the combined cycle (CC) as thermodynamic power cycle and a multi-tower solar field configuration together with open volumetric air receivers.
- Experimental and numerical evaluation of a small array of ceramic foam volumetric absorbers. This paper presents intermediate-scale experimental tests of a small 2 x 2 array of ceramic foam absorbers at CIEMAT-PSA (SSPS-CRS tower). July 2019.
- Heliostat structural optimization: A study of wind load effects with CFD-FEM methods. In solar power tower plants, heliostat mirrors reflect the sunlight onto the receiver. The mirrors are supported
by the facet structure and when it is deformed, the mirror quality is affected (the sunlight is reflected with less accuracy). This
study shows that an improvement in optical quality in the facet structure could be achieved; while still maintaining the
material needed in the facet structure. November 2018.
- Experimental evaluation of volumetric solar absorbers – Ceramic foam vs. an innovative rotary disc absorber concept. This paper presents the experimental evaluation of two volumetric solar absorber concepts. It compares the thermal performance of conventional foam absorbers with that of an innovative rotary disc absorber design. . November 2018.
- Numerical and experimental evaluation and optimization of ceramic foam as solar absorber – Single-layer vs multi-layer configurations. This article was published by CAPTure project in the scientific online platform ‘Science Direct’, in January 2018.
- Numerical and experimental evaluation and optimization of ceramic foam as solar absorber – Single-layer vs multi-layer configurations. This work targets the numerical and experimental evaluation of ceramic foam as solar absorber material for solar thermal power generation. Two different 1-D model types with local thermal non-equilibrium (LTNE) have been developed independently at CENER and Fraunhofer-IKTS. November 2017.
- Modeling and simulation of fixed bed regenerators for a multi-tower decoupled advanced solar combined cycle. Two dynamic models of fixed bed regenerators for metallic and ceramic configurations have been developed in Modelica. These models have been both worked out within CAPTURE European project and will serve as design tool for a fixed bed regenerative heat exchange system. The present article describes in detail both models and presents a case study that compares experimental and simulation results for the testing of a ceramic honeycomb regenerative matrix. July 2017.
- Abstract submitted to SolarPACES 2017. This work was presented by CAPTure partner, EDF, as a poster under the title ‘Optimization of a Decoupled Combined Cycle Gas Turbine Integrated in a Modular Multi-Tower Solar Power Plant‘.
- Abstract submitted to give a presentation during the 4th Cellular Materials (CellMAT) Conference in 2016: Property adjustment of open-celled ceramic foams for high temperature applications assisted by numerical modelling.
