Thermal Stress of Solid Oxide Reactors in Universal Electrode-Supported-Type Configurations

Abstract

Residual stress evaluation in Solid Oxide Reactors (SORs) is essential issue to ensure mechanical durability and reliability. However, it requires specialized knowledge and skill in experimental techniques, and computing. In this study, two diagrams consist of dimensionless numbers based on thermomechanical properties: Young’s modulus, Poisson’s ratio and thermal expansion coefficient, and geometrical parameters: thickness of each layer, were drawn for electrode-supported-type configurations. These diagrams provided researchers and engineers in the field of SORs the way to estimate thermal stress.
