Quantitative measurement of water vapor condensation in homogeneous and heterogeneous porous media
The focus of this study is to measure and analyze the complex condensation process of vapor in cracked heterogeneous porous media, in-situ, using quantitative time-resolved neutron tomography. The experiment is performed by injecting well-characterized vapor at pre-established flow rates into porous samples with a known macroscopic heterogeneity (cracks and fracture network) superposed to the inherent heterogeneities (such as grains, pores, and capillary network). Based on the results from previous campaigns at ILL, we will improve the quantitative accuracy of the vapor content. This will be achieved by adopting several calibration methods to extract the precise density field of water saturation as well as improvements on the previous experiment setup. The evolution of the 3D saturation fields obtained by the in-situ neutron imaging accompanied by the microstructural characterization of the sample obtained by X-ray tomography will be used to highlight the contribution of the mechanisms that affects the propagation of water accumulation in the specimen, and to calibrate physical parameters of an already developed multi-phase multi-component numerical flow model.
