A COMMENT ON “LATTICE BOLTZMANN SIMULATION AND FRACTAL ANALYSIS OF EFFECTIVE THERMAL CONDUCTIVITY IN POROUS MEDIA” KU Leuven
In May 2020, this journal published the paper “Lattice Boltzmann simulation and fractal analysis of effective thermal conductivity in porous media”, applying and comparing a lattice-Boltzmann-based simulation model and a fractal-material-based analytical model for effective thermal conductivity of porous media. This comment, which is considered a post-publication review, reveals however that the paper’s fractal model often exceeds the upper ...
Microscopic localisation of hydrophilically oriented pore bodies and throats in hydrophobised porous materials KU Leuven
Internal insulation of the building envelope is a prime topic in building physics, due to the risk of moisture problems that this technique entails. As a remedy to these problems, the application of a water repellent agent, which reduces the amount of absorbed wind-driven rain, has become popular in recent years. When such an agent is applied on a building material, it penetrates the pore network of the material, hereby attaching itself to the ...
Fracture mode analysis of cementitious mortars by simultaneous application of 4D-XCT and acoustic emission technique KU Leuven
Cementitious brittle construction materials are susceptible to fracturing due to their heterogeneous material composition and relatively weak bond between the aggregates and paste. Hence, enhanced methods of fracture analysis in these materials are an important subject of research. The acoustic emission technique (AET) is frequently used in the study of brittle construction materials, yet the random nature of cracking and the het erogeneity of ...
Microscopic Validation of a Pore Network Model for Hygric Properties of Porous Materials KU Leuven
In a pore network model, microscopic moisture storage and transport processes are modeled at pore level after which this information is extrapolated to obtain macroscopic properties describing the material's moisture behaviour. Such a model is typically validated by comparing measured and simulated macroscopic properties. However, due to the uncertainty associated with the experimental property determination, a possibly incorrect description of ...
