Morphological characterization of shocked porous material

Morphological characterization of shocked porous material

Morphological measures are introduced to probe the complex procedure of shock wave reaction on porous material. They characterize the geometry and topology of the pixelized map of a state variable like the temperature. Relevance of them to thermodynamical properties of material is revealed and various experimental conditions are simulated. Numerical results indicate that, the shock wave reactio...

Applications of Image Processing Technique in Porous Material Characterization

Nondestructive testing (NDT) provides safe operation to engineering components – it eliminates the risk of damage during operation, and does not require specific sample preparation. It has been widely used to detect and evaluate defects, or measure properties of different types of materials and engineering structures. Examples of NDT techniques include ultrasonic, radiography, infrared thermogr...

Morphological Characterization and Effective Thermal Conductivity of Dual-Scale Reticulated Porous Structures

Reticulated porous ceramic (RPC) made of ceria are promising structures used in solar thermochemical redox cycles for splitting CO₂ and H₂O. They feature dual-scale porosity with mm-size pores for effective radiative heat transfer during reduction and µm-size pores within its struts for enhanced kinetics during oxidation. In this work, the detailed 3D digital representation of the complex dual-...
