Volume of fluid (VOF) method is a sharp interface employed for simulations two phase flows. Interface in VOF usually represented using piecewise linear line segments each computational grid based on the volume fraction field. While cartesian coordinates conserve mass exactly, existing algorithms do not show machine-precision conservation axisymmetric coordinate systems. In this work, we propose...

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...

in this research, numerical simulation of a symmetric impact of a 2-d wedge, considering dynamic equations in two-phase flow is taken into account. the two-phase flow around the wedge is solved based on finite volume method and volume of fluid (vof) scheme. the dynamic mesh model is used to simulate dynamic motion of the wedge, thereby the effects of different dynamic meshes in both structured ...

Direct ink writing (DIW) is an extrusion-based additive manufacturing (AM) technique. One of the required factors for printing quality in DIW to extrude continuous and tubular freeform extruded filaments (FEF) with diameters close nozzle inner diameter. This paper established a simulation model FEF volume fluid (VOF) method then evaluated based on results. First, properties including density, s...
