Development of an Optimal Control Strategy for the Themis Solar Plant: Part I—Themis Transient Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This first part of a twofold article is devoted to the presentation of a model of the Themis central receiver solar plant. The Themis experiment showed that the energy balance is deteriorated ...
Optical Properties of Plasma-Sprayed ZrO2-Y2O3 at High Temperature for Solar Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experimental determinations of the absorptivity and of the total hemispherical emissivity of plasma-sprayed ZrO2-7wt%Y2O3 layers were performed in the range of temperature 1000 K–2300 K. For this ...
Development of an Optimal Control Strategy for the Themis Solar Plant: Part II—Themis Model Operation: Validation and Simulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This second part of a twofold article presents the operating system associated with the physical model. Basic control laws and operating rules are described, and the global model is validated ...
Flux Distribution Delivered by a Fresnel Lens Used for Concentrating Solar Energy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The flux distribution delivered by a Fresnel lens when concentrating solar energy is characterized. The flux is measured with a Si photo-detector equipped with an integrating sphere. Flux mapping ...
Surface Hardening of Steel Using Highly Concentrated Solar Energy Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A recent French contribution in the field of surface hardening of steel using concentrated solar energy is presented. Single spot and continuous scanning processes have been investigated in a ...
Thermal Performances of a High Temperature Air Solar Absorber Based on Compact Heat Exchange Technology
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the framework of the French PEGASE project (Production of Electricity by GAs turbine and Solar Energy), CNRS/PROMES laboratory is developing a 4 MWth pressurized air solar receiver with a ...
Detailed Performance Analysis of a 10kW Dish∕Stirling System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The CNRS-Promes dish∕Stirling system was erected in Jun. 2004 as the last of three country reference units built in the “Envirodish” project. It represents the latest development step of the ...
