Abstract

An emulsion layer is a mixture of two or more liquids in which one of them the dispersed phase, is present as droplets of microscopic size, distributed throughout the other, called continuous phase. The existence of such layer between oil and water is due to the crude properties, [...]

Abstract

This study presents the results from detailed experiments of the two-phase pressurized flow behavior during the rapid filling of a large-scale pipeline. The physical scale of this experiment is close to the practical situation in many industrial plants. Pressure transducers, water-level [...]

Abstract

Gas entrainment is one of the major defects caused in the casting filling process. Since the particle method is a Lagrangian method that does not use a lattice, it can easily analyze large deformations and boundary movements, so it has the potential to be applied to gas defect [...]

Abstract

Fluid flowing through pipelines often encounters fittings such as elbows. Although it is true that two-phase flow patterns observed in elbows are qualitatively the same as those seen in straight pipes, the presence of a pipe elbow can modify relative positions and local velocities [...]

Abstract

When simulating high Reynolds number two-phase flow, boundary layers develop at the interface, which are much thinner compared to the capillary length-scales that are of interest. Resolving such an interface layer is expensive and therefore it is often not resolved in a simulation. [...]

Abstract

The paper addresses a novel interface-capturing approach for two-phase flows governed by the five-equation diffuse interface model. To suppress the numerical diffusion of the interface, we introduce a primitive sub-cell reconstruction based on volume fractions in neighbouring cells. [...]

Abstract

In numerical research about two-phase flow in tube bundles, mainly two trends are distinguishable. On the one hand, some studies start from the assumption that only relatively small bubbles occur in a continuous liquid flow, for which typically Eulerian-Lagrangian modelling is appropriate. [...]

Abstract

The reliable predictions of liquid holdup and pressure drop are essential for pipeline design in oil and gas industry. In this study, the drift-flux approach is utilized to calculate liquid holdups. This approach has been widely used in formulation of the basic equations for multiphase [...]

Abstract

In recent years, the authors and co-workers have developed a 3D finite element model for coupled thermo-hydro-mechanical (THM) problems in fractured rock masses. Zero-thickness interface elements are used for taking into account explicitly the effect of fractures and discontinuities [...]
