The paper considers the formation of a ventilated cavity in flow water behind streamlined body. Numerical modeling two-phase is based on Volume Fluid (VOF) method. system equations for water-air mixture consists Navier-Stokes equation, continuity energy conservation and diffusion state (ideal gas Boussinesq approximation). This closed by Smagorinsky model turbulence (the large eddies). geometry...

High sensitivity and a high speed nanoscale measurement becomes an important subject in modern industry, when analysis of high speed moving nanoscale objects on a surface is required. Recently we have shown a possible approach to this problem using singular beam microscopy. Singular beam microscopy performs scanning by utilization of the relative movement between the focused singular beam and t...

This paper addresses the combined effects of couple stresses, thermal radiation, viscous dissipation and slip condition on a free convective flow of a couple stress fluid induced by a vertical stretching sheet. The Cogley- Vincenti-Gilles equilibrium model is employed to include the effects of thermal radiation in the study. The governing boundary layer equations are transformed into a system o...

Contrast in capillary pressure of heterogeneous permeable media can have a significant effect on the flow path in two-phase immiscible flow. Very little work has appeared on the subject of capillary heterogeneity despite the fact that in certain cases it may be as important as permeability heterogeneity. The discontinuity in saturation as a result of capillary continuity, and in some cases capi...

Discrete fracture network (DFN) is an effective means of describing the coupling heat flow in underground fractured rock mass. In this paper, improved DFN proposed by introducing correlation function trace length and aperture, which more consistent with real data. Next, based on model, influence roughness fluid transmission was evaluated, relationship between aperture joint coefficient (JRC) es...

The present study reported of the numerical investigation of a high-speed wet steam flow through an asymmetric nozzle. The spontaneous non-equilibrium homogeneous condensation of wet steam was numerically modeled based on the classical nucleation theory and droplet growth rate equation combined with the field conservations within the computational fluid dynamics (CFD) code of ANSYS Fluent 13.0....
