PREFACE: GEO-ENERGY AND GEO-RESOURCES: MODELING AND APPLICATION J. Porous Media (IF 1.752) Pub Date : 2019-01-01 Mohammad Rezania, Mohaddeseh Mousavi Nezhad, Masoud Jabbari
Efficient usage of underground resources is becoming increasingly important, as it is linked with the principle of sustainable development. Underground geological formations contain significant amounts of oil, gas and heat and can also be used for storage of carbon dioxide, natural gas or radioactive waste. Development of technologies to utilize these underground resources and spaces requires appropriate

Homogenize Coupled Stokes-Cahn-Hilliard System to Darcy's Law for Two-Phase Fluid Flow in Porous Medium by Volume Averaging J. Porous Media (IF 1.752) Pub Date : 2019-01-01 Jie Chen, Shuyu Sun, Zhengkang He
A technique of local volume averaging is applied to obtain general equations which depict mass and momentum transport of incompressible two-phase flow in porous media. Starting from coupled Stokes-Cahn-Hilliard equations for incompressible twophase fluid flow, the averaging is performed without oversimplifying either the porous medium or the fluid mechanical relations. The resulting equations are Darcy’s

A HIERARCHICAL APPROACH TO DETERMINING ACOUSTIC ABSORPTION PROPERTIES OF POROUS MEDIA COMBINING PORE-RESOLVED AND MACROSCOPIC MODELS J. Porous Media (IF 1.752) Pub Date : 2018-01-01 Sonja Uphoff, Manfred Krafczyk, Konstantin Kutscher, Katherina Rurkowska, Sabine Langer, Nicolas Lippitz, Benjamin Faßmann
Acoustic properties of porous media are very important for numerous industrial applications, the typical goal being to maximize broadband absorption to decrease the sound pressure level of the engineering system under consideration. Up to now acoustic absorption for porous media with complex inner geometry is determined experimentally, as acoustic simulations on the pore scale are computationally challenging

FREE CONVECTION HEAT AND MASS TRANSFER OF A NANOFLUID PAST A HORIZONTAL CYLINDER EMBEDDED IN A NON-DARCY POROUS MEDIUM J. Porous Media (IF 1.752) Pub Date : 2018-01-01 A. Subba Rao, V. Ramachandra Prasad, O. Anwar Bég, M. Rashidi
In the present paper, we analyzed the laminar boundary layer flow and heat transfer from a horizontal cylinder in a nanofluid-saturated non-Darcy porous medium in the presence of thermal radiation. This is the first paper presenting non-similar solutions for such a regime.The boundary layer conservation equations,which are parabolic in nature,are normalized into non-similar form and then solved computationally

Coupled numerical simulation of multi-layer reservoir flow with fine-separated-layer water injection J. Porous Media (IF 1.752) Pub Date : 2018-01-01 Dapeng Gao, Yuewu Liu, Jigen Ye, Songqi Pan, Shaoji Hou, Daigang Wang
Many multilayer sandstone reservoirs have reached extreme high water content and high recovery stage after long time waterflooding. These inner LPTOLs have been the main potential reserves. Lean-stratified water injection is one of the most important technologies to increase production and develop potential for multilayer oilfields with extreme high water content. However, traditional models cannot
