Etude du comportement thermomécanique de matériaux céramiques sous irradiation solaire concentrée : développement expérimental et modélisation

Abstract : Among the available technologies for carbon-free and competitive electricity production, solar tower power plants can achieve the best efficiency. Commercial development is currently focused on tubular or surface receivers, as they allow a low-intricacy design. The major challenge is to cyclically operate these receivers at temperatures above 800°C, which involves the use of durable and high performance materials. Refractory alloys and ceramics have adequate properties, but their damage evolution under these specific conditions is still poorly understood. An innovative set up based on the acoustic emission technique has been designed and realized with a view to scrutinize these materials in situ behavior. Indeed, acoustic emission enables to estimate the severity, the type, and the position of a damage appearing under concentrated solar irradiation tests. Besides, an original numerical method has been developed to identify the suitable test conditions for relevant experimental aging.
