Revealing how interfaces in stacked thin fibrous layers affect liquid ingress and transport properties by single-sided NMR

Continuum-scale modeling of water infiltration into a stack of two thin fibrous layers and their inter-layer space

“…The main objective of this study is to test both traditional Richards model and the RCM against experimental data obtained in our previous work (Mohebbi et al, 2018) on through-plane liquid infiltration in a stack of two thin fibrous layers. In those experiments, water was fed at a small region in the middle of the top layer.…”

“…This paper is organized as follows. We start with describing the measurement method, the experimental results, and the materials used in our previous work (Mohebbi et al, 2018) in Section 2. Next, in Section 2.3, we describe the characterization of the thin fibrous layers, and obtain properties that are used in the modeling study.…”

“…In our previous study (Mohebbi et al, 2018), two square thin polyester layer samples with dimension of 10 by 10 mm 2 were placed on top of each other. A Plexiglas plate with a hole in the center was placed on the upper layer in order to impose a pressure of 0.3 psi (ffi2.1 kPa) as shown in Fig.…”

“…Detailed description of the experiments was presented in Mohebbi et al, 2018. Here, we provide a short description of the experiments and present results of the high flow rate experiment (Adopted from Mohebbi et al, 2018). Additionally, signal intensity profiles of high flow rate experiment at a large number of times and results of the low flow rate experiment are given here for the first time.…”

“…Note that the experimental data are scattered more in the low flow-rate experiment. This artifact can be attributed to the large (Mohebbi et al, 2018).…”
