“…These are the Lagrangian or Eulerian approaches for tracking the position of interface based on one or two sets of conservation equations for the phase change. Although two sets of conservation equations with the Lagrangian tracking approaches such as Maker and cell (MAC) methods and the front tracking method (Deen et al, 2009) are quite accurate, nowadays one set conservation equations with the Eulerian approach is more generally used because numerical problems arise when a re-meshing process in Lagrangian tracking approaches is required to model high distortions of interfaces or interface break up. A famous set of conservation equations with Eulerian approach is the VOF (volume of fluid) method, which was pioneered by Hirt and Nichols (Hirt & Nichols, 1981).…”

“…I n t he f ront-tracking method [47,46], a stationary Eulerian grid is used for the fluid flow and the interface is tracked explicitly by a separate Lagrangian grid. This method is extremely accurate but also rather complex to implement due to the fact that dynamic re-meshing of the Lagrangian interface mesh is required [10]. Contrary to LS and VOF method, automatic merging of interfaces does not occur, and difficulties arise when multiple interfaces interact with each other as in coalescence and break-up.…”

This paper presents a methodology for simulation of two-phase flows with surface tension in the framework of unstructured meshes, which combines volume-of-fluid with level-set methods. While the volume-of-fluid transport relies on a robust and accurate polyhedral library for interface advection, surface tension force is calculated by using a level-set function reconstructed by means of a geometrical procedure. Moreover the solution of the fluid flow equations is performed through the fractional step method, using a finite-volume discretization on a collocated grid arrangement. The numerical method is validated against two-and three-dimensional test cases well established in the literature. Conservation properties of this method are shown to be excellent, while geometrical accuracy remains satisfactory even for

“…The IB method embeds a direct forcing method as proposed by Uhlmann [29] and Wang [31]. Differently from [10], the collision model, to account for dissipative particle-particle and particle-wall collision, has been not considered yet. Both methods are implemented in the context structured adaptive mesh refinement in order to allow variable spatial resolution along the interface, which can be a solid-fluid interface or a fluid-fluid interface.…”

Abstract. In this paper a simulation model is presented for the Direct Numerical simulation (DNS) of multiphase flow. This method combines the Volume of fluid model and Immersed Boundary method in order to investigate water-oil flow-pattern. The simulations were carried out on structured cartesian adaptive mesh refinement (SAMR), where the the Immersed Boundary represents the circular tube via Direct Forcing Method (DFM). The Volume of Fluid based on piecewise linear reconstruction interface, allow to define the fluid-fluid interface using a three dimensional version of the continuum surface force (CSF) model of Brackbill et al. (1992). The Navier-Stokes equations are discretized in the entire domain using a finite difference scheme, where a temporal discretization is based on SBDF scheme, with adaptive time stepping. The capabilities of the hybrid VOF-IB model are demonstrated with examples in wich complex topological changes in the interface are encountered. The overall methodology has been through a careful, series of verification tests whose results are reported. An oil-water flow-pattern application is presented.
