چکیده
Abstract The effects of periodicity assumptions on the macroscopic properties packed porous beds are evaluated using a cascaded Lattice-Boltzmann method model. bed is modelled as cubic and staggered packings mono-radii circular obstructions where porosity varied by altering circle radii. results for validated previously published results. For unsteady flows, it found that one unit cell not enough to represent all structures fluid flow which substantially impacts permeability dispersive bed. In steady region, single shown accurately across cases studied

the effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
Modelling Wells in Porous Media Ows
In this paper, we prove the existence of weak solutions for mathematical models of miscible and immiscible ow through porous medium. An important diiculty comes from the modelization of the wells, which does not allow us to use classical variational formulations of the equations.
متن کاملLBM mesoscale modelling of porous media
Permeability is one of the most important bulk properties for the characterization of fluid flow in porous media. However, despite all the considerable body of research work over the past years using experimental, analytical, and numerical approaches, its determination is still a challenge. The methodologies, which have been used to measure, calculate and predict the permeability of different t...

امروزه سالیتون ها بعنوان امواج جایگزیده ای که تحت شرایط خاص بدون تغییر شکل در محیط منتشر می-شوند، زمینه مطالعات گسترده ای در حوزه اپتیک غیرخطی هستند. در این راستا توجه به پدیده پراش گسسته، که بعنوان عامل پهن شدگی باریکه نوری در آرایه ای از موجبرهای جفت شده، ظاهر می گردد، ضروری است، زیرا سالیتون های گسسته از خنثی شدن پراش گسسته در این سیستم ها بوسیله عوامل غیرخطی بوجود می آیند. گسستگی سیستم عامل...
An Investigation on the Effects of Charged Polyacrylamide Injection on Asphaltene Deposition in Porous Media
This study has been investigated, the effects of three different polar polyacrylamides (anionic, cationic, and nonionic) on asphaltene deposition in porous media. All experiments were carried out in various dead oil flow rates (0.2, 0.1 and 0.02 cc/min) and different polymer concentrations (500, 2500, 4000 ppm). The results indicated that asphaltene precipitation was affected by the presence of...
