Prediction of the effective thermal conductivity of porous building blocks based on their pore structure

Last September a Ph.D. dissertation was presented at the KU Leuven by Wouter Van de Valle, titled “Prediction of the effective thermal conductivity of porous building blocks based on their pore structure”. The dissertation is free to download on the university portal.

The research focuses on the thermal conductivity of porous materials by using a numerical framework to simulate the effect of the pore structure. greenTEG’s gSKIN XI sensor was used to validate the model, which uses 3D voxel images of the pore structure acquired via micro-computed tomography or virtual generation techniques. The study analyses the influence of pore size in micrometers down to the nanometer range. greenTEG congratulates Wouter for his achievement. We are always happy to contribute to the advance of science with our sensors!

Building elements thermal performance research is a great use case for heat flux sensors. At greenTEG, we have been working on this topic for several years. If you want to learn more about this topic, we recommend to e.g. downloading our Introduction to U-Value measurement methods for building elements.
