In the nanochannel flow behavior with respect to expand their applications in modern systems is of utmost importance. According to the results obtained in this study, the condition of nonslip on the wall of the nanochannel is not acceptable because in the nano dimensions, slip depends on different parameters including surface roughness. In this study, keeping the side area roughness, deformatio...

dense medium cyclone is a high capacity device that is widely used in coal preparation. it is simple in design but the swirling turbulent flow, the presence of medium and coal with different density and size fraction and the presence of the air-core make the flow pattern in dmcs complex. in this article the flow pattern simulation of dmc is performed with computational fluid dynamics and fluent...

The modeling of hydrocarbon reservoirs and of aquifer-aquitard systems can be separated into two activities: geological modeling and fluid flow modeling. The geological model focuses on the geometry and the dimensions of the subsurface layers and faults, and on its rock types. The fluid flow model focuses on quantities like pressure, flux and dissipation, which are related to each other by rock...

[1] Ground surface displacement (GSD) in large calderas is often interpreted as resulting from magma intrusion at depth. Recent advances in geodetic measurements of GSD, notably interferometric synthetic aperture radar, reveal complex and multifaceted deformation patterns that often require complex source models to explain the observed GSD. Although hydrothermal fluids have been discussed as a ...

Modern computational fluid dynamics simulations are capable of the detailed simulation of fluid flow. The output data sets of these simulations are very large and information rich. The importance of data visualization is clearly recognized for the presentation of these data sets. For gaining new insight in the nature of flow, interactive visualization methods are essential. The goal of our work...

This paper is devoted to the numerical modeling and simulation of hydrodynamic and dissipation processes in damper systems, where the working element is a magnetic fluid drop around a permanent magnet. Flow patterns and dimensionless dissipation coefficient depending on the Reynolds number and magnet position are established. r 2004 Elsevier B.V. All rights reserved. PACS: 02.60.Cb; 02.70.Dh; 4...
