Ostwald ripening of trapped bubbles in porous media is relevant to several subsurface (e.g., CO2 storage) and manufacturing fuel cells) applications. A fundamental question common both is: how does an initially heterogeneous distribution bubble sizes, PDFo, evolves towards a stable equilibrium distribution, PDFe? And what We develop pore-network model (PNM) that simulates the temporal evolution...

Within the scope of literature, influence openings within infill walls that are bounded by a reinforced concrete frame and excited seismic drift forces in both in- out-of-plane direction is still uncharted. Therefore, 3D micromodel was developed calibrated thereafter, to gain more insight topic. The micromodels were against their equivalent physical test specimens in-plane, driven tests on fram...

This work reviews the transient two-phase flow in porous media with engineering applications Geotechnics. It initially overviews constitutive relationships, conventional theories, and experiments. Then, corresponding limitations are discussed according to conflicting observations multiphase interfacial dynamics. Based on those findings, dynamic nonequilibrium effects were so defined, which coul...

Solute transport in heterogeneous and fractured systems is a complex process given the permeability contrasts time scales discrepancies of high-permeability versus low-permeability regions. We studied this phenomenon by injecting solute (dyed water) micromodel comprising single channel contact with porous medium evaluated mass exchange across interface between (resembling free flow media region...

Aims Mechanical testing has been performed to evaluate the bond strength of root canal fillings to dentin surface of root canal. In this scenario, the push-out testing is widely used, although the results from several studies are sometimes inconsistent (1-4). The variability of specimen’s geometry and thickness; and diameters of tip applying the load are some factors that can to alter the stres...

In this paper, we analyze a multiscale method developed under the heterogeneous multiscale method (HMM) framework for numerical approximation of multiscale wave propagation problems in periodic media. In particular, we are interested in the long time O(ε−2) wave propagation, where ε represents the size of the microscopic variations in the media. In large time scales, the solutions of multiscale...
