Micromodels are important for studying various pore-scale phenomena in hydrogeology. However, the fabrication of a custom micromodel involves complicated steps with cost-prohibitive equipment. The direct micromodels 3D printer can accelerate and reduce cost. A stereolithography (SLA) is one best options because it has sufficient printing performance relatively inexpensive. not without drawbacks...

The aim of this study is to examine displacements, strains and stresses as well predict possible failure mechanisms arising at the yarn-matrix level a test specimen railway composite cord-rubber air brake tube undergoing uniaxial tension by microscale modelling.Furthermore, paper also aims verify material properties micromodel specimen.The based on macromodels (by matching boundary conditions m...

A transient, three-dimensional model for thermal transport in heat pipes and vapor chambers is developed. The Navier–Stokes equations along with the energy equation are solved numerically for the liquid and vapor flows. A porous medium formulation is used for the wick region. Evaporation and condensation at the liquid–vapor interface are modeled using kinetic theory. The influence of the wick m...

We present a systematic, quantitative assessment of the impact of pore size disorder and its interplay with flow rates and wettability on immiscible displacement of a viscous fluid. Pore-scale simulations and micromodel experiments show that reducing disorder increases the displacement efficiency and compactness, minimizing the fluid-fluid interfacial area, through (i) trapping at low rates and...

To take capillary effect into account, a series of primary drainage experiments of water by a sample oil fluid have been studied. The experiments performed under different low flow rates on a horizontal glass type micromodel as a model of porous media. Based on conventional macroscopic flow equations, the relative permeabilities and capillary pressure are determined by parameter estimation tech...

The MIT Faculty has made this article openly available. Please share how this access benefits you. Your story matters. b Micromodels with a simplified porous network that represents geological porous media have been used as experimental test beds for multiphase flow studies in the petroleum industry. We present a new method to fabricate reservoir micromodels with heterogeneous wetting propertie...
