in this paper, direct numerical simulation of two-phase incompressible gas-liquid flow for simulation of bubble motion in a microtube is presented. microtube radius is 10 µm. the interface is tracked using volume of fluid (vof) method with continuous surface force (csf) model. the flow is solved using a finite volume scheme, based on piso algorithm. numerical simulation is performed on a axisym...
In this paper, the flow pattern around the perpendicular and inclined groynes were simulated in three-dimensional using the Fluent software, which solves the flow equations using the finite volume method and cell-center scheme. The prismatic grids were used to descretize the computational domain. The perpendicular groyne was first investigated to verify the model results and the inclined groyne...
This paper begins with presenting a mathematical model for contaminant transport in the fractured vuggy porous media of a species of contaminant PCP . Two phases are numerically simulated for a process of contaminant and clean water infiltrated in the fractured vuggy porous media by coupling mixed finite element MFE method and finite volume method FVM , both of which are locally conservative, t...
an enhamced scheme is introduced for the solution of two dimensional umsteady euler equations. the finite- volume method of jameson et al. is modified by devicing a pnessune sensor in cell flux calculations. then the discretized gorerning equations ane relaxed in time until na steady state is reached. an appropriate model for the artificial dissipation was also employed. several tests wene cond...
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 ...
