Evapoporometry is a technique for determining the pore size distribution of a porous medium through measuring the evaporated mass. This study investigates evapoporometry through numerical simulations on model pore networks, providing a detailed understanding of the underlying physics involved. The simulations demonstrate the importance of accurately determining the evaporation rate, as it affects the characterization of both pore body size and throat size distributions.
Evapoporometry is a technique aiming at characterizing the pore size distribution of a porous medium from evaporated mass measurements. In this work, evapoporometry is studied from numerical simulations on model pore networks allowing a detailed analysis of the underlying physics at play in the technique. Simulations indicate that both the pore body size and throat size distributions can be characterized and pinpoint the need of a very accurate determination of the evaporation rate. This is notably illustrated by varying the evaporated mass acquisition time step. Evapoporometry and liquid-liquid displacement porometry techniques are discussed comparatively in relation with experimental works reporting differences between the pore size distributions identified through both techniques.
