Volume Of Fluid (VOF) Multi-phase ANSYS Fluent CFD Simulation Training Package for BEGINNER Users (Part-I)
This training package includes 10 practical Multi-phase Volume Of Fluid (VOF) exercises using ANSYS Fluent software. MR CFD suggests this package for BEGINNER users who tends to learn the simulation process of multi-phase problems without any strong background.
Project number 1 simulates a three-phase flow mixture within a channel with a square cross-section. These three phases include air, water, and kerosene. The channel consists of a vertical section consisting of two inlet sections at its top and bottom and a zigzag section in the horizontal direction with an outlet section at its end. To simulate multi-phase flow in the present model, the VOF multiphase model has been used. Also, inside the canal, a porous environment with a porosity coefficient of 0.1 is located. The trigger for air and oil flowing into the duct is the pressure difference
Project number 2 simulates the infiltration of water flows into a cubic porous medium. In this modeling, a cube block is designed as a porous medium. The water flow enters it from a circular section at the bottom of the blocks is also assumed that there is only the air inside the block in the initial state, and then water flow penetrates it. Therefore, to define a two-phase flow consisting of water and air, the VOF or volume of fluid model is used.
Cohesion & Adhesion
In project number 3, the two-phase flow of water and air flowing over two cylinders considering cohesion and adhesion is simulated. The water will enter the computational domain with a velocity of 2.6m/s, and it flows over the cylinders’ surfaces. The realizable k-epsilon model is exploited to solve fluid flow equations, and VOF multiphase model is used to investigate the phase interactions.
In project number 4, ANSYS Fluent software has been used for numerical simulation of water droplet collapse on the wall in two modes of non-slip condition and shear stress condition. The VOF model has been used to simulate and solve the two-phase flow field equations.
In project number 5, a numerical simulation of droplet collapse with two different contact angles has been done. The VOF model has been used to simulate and solve the two-phase flow field equations. The purpose of this project is to investigate the collapse of water droplets on the wall at the contact angle of 90 degrees and 120 degrees.
In project number 6, a water droplet falling in the air is simulated. Therefore, the two-phase flow model is used to simulate the initial air phase and the secondary water phase. This simulation only includes fluid analysis and does not discuss thermal analysis. The purpose of the simulation is to investigate the drop behavior during a downward slope and the extent of its volume changes.
Gas Sweetening (Volume of Fluid)
Project number 7 deals with the hydrodynamic simulation of a gas sweetening system. Gas sweetening is generally the process of removing hydrogen sulfide, carbon dioxide, mercaptans, and other impurities from natural gas streams and synthetic gas to make the gas suitable for transportation and use. In this project, two materials are defined within the computational domain, which includes a particular sour gas and an amine stream; However, because this project only deals with the hydrodynamic modeling of this process, the gas removal process does not occur due to the occurrence of a physical or chemical phenomenon
Pigging oil flow
Project number 8 simulates the pigging oil flow inside pipelines. Inside the pipelines in this model, there is a piece called a pig. the simulation process is performed in two different modes; Thus, oil flow with different inlet speeds including 0.9 m/s and 1.9 m/s enters the interior of the pipeline. Also, the VOF multiphase model has been used to define the oil and gas materials in the pipelines, and two materials have been defined as gas-oil and petro in the present model.
Solidification, also known as freezing, is a phase change of matter that results in the production of a solid. Generally, this occurs when the temperature of a liquid is lowered below its freezing point. In project number 9, the solidification process of molten steel inside a solidifying chamber is investigated. Water is used to lower the molten steel’s temperature and accelerate the solidification process. The simulation is done using the VOF model for the three phases of air, water, and steel.
Shower Channel Drain (Volume of Fluid)
In project number 10, a shower drain inside an inclined channel with 120 water inputs is simulated and analyzed. In order to analyze the air and water flow inside the channel, the standard k-epsilon model with the use of standard wall functions is exploited. The multi-phase VOF model has been used to investigate the two-phase flow of air and water within this channel.
