Modelling Surface Tension Dominated Multiphase Flows Using the Vof Approach
نویسندگان
چکیده
Low-capillary number or surface tension dominated flows are found in a number applications, ranging from small scale microfluidics up to larger scale analysis of microgravity sloshing. This paper evaluates the possibility of modelling of surface tension dominated multiphase flows using an Eulerian volume-of-fluid (VOF) approach with high-resolution surface capturing. With the aim of improved stability and computational efficiency, a conservative formulation is employed that ensures the surface tension induced parasitic currents are negligibly small. This is achieved by utilising a smoothed volume fraction to obtain a more accurate representation of the curvature when computing the surface tension.

A New Method for Calculating Interface Normal Vectors and Curvatures when Modelling Free-Surface Flows
In simulating free-surface flows, the interface normal vectors and curvature are needed for modelling surface tension e↵ects. We present a new method for accurately calculating these quantities. In this method, an entirely di↵erent approach is taken, compared to common methods where normals and curvature are obtained from the Volume-of-Fluid (VOF) or Level Set (LS) functions. In this fixed-grid...
متن کاملThe Indication of Two-Phase Flow Pattern and Slug Characteristics in a Pipeline Using CFD Method
Multiphase flows are commonly encountered in oil and gas industries. The transport of multiphase flow causes the formation of slug, the increase of pressure drop and the possibility of phase changes therefore, a set of simulation runs was performed to predict flow regimes in a horizontal pipeline, and the results were compared with the Baker chart. The effects of small downward inclinations of ...

Abstract: In this study an algorithm for mold-filling simulation with consideration of surface tension has been developed based on a SOLA VOF scheme. As the governing equations, the Navier-Stokes equations for incompressible and laminar flows were used. We proposed a way of considering surface tension in mold-filling simulation. The proposed scheme for surface tension was based on the conti...

متن کاملNumerical Simulation of Flow Pattern around the Bridge Pier with Submerged Vanes
Bridges are very important for establishing communication paths. For this reason, it is important to control scour around bridge piers. Several methods have been proposed for scour control. One of the most useful methods is the use of submerged vanes. In the other hand, laboratory circumstances force many considered effective factors to be skipped in the scour phenomenon. In this situation, the...
