A comprehensive model to predict the stress evolution in a multilayer coating during its use in solar receivers is proposed. The model takes into account residual stress in the coatings, thermal gradient in the structure and high temperature phenomena like oxide scale growth and creep relaxation. The numerical tool developed in this work can help to understand the complex interplay of these phenomena occurring in all the materials involved. Additionally, the present model can be used to assess high temperature data like creep when it is compared with an experimental case.

建模太阳能接收器中的多层涂层系统

提出了一种预测多层涂层在太阳能接收器中使用过程中应力演变的综合模型。该模型考虑了涂层中的残余应力，结构中的热梯度以及高温现象，例如氧化物垢的生长和蠕变松弛。在这项工作中开发的数值工具可以帮助理解所有涉及的材料中发生的这些现象的复杂相互作用。另外，当与实验案例进行比较时，本模型可用于评估高温数据，例如蠕变。
