The problem simulates a three-phase flow mixture within a channel with a square cross-section by ANSYS Fluent software.
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. In the initial state, only the airflow inside the channel is available.
At the start of the simulation process, water flow enters the channel from the upper inlet section and kerosene flow from the lower inlet section.
The current model is designed in three dimensions using Design Modeler software. The model consists of a vertical channel for the entry of fluid flows and a zigzag path connected to it in the horizontal direction. The zigzag path is in the form of teeth perpendicular to each other.
The canal’s cross-section in the route is square with a side length of 0.0002 m. There are two sections as flow inputs at the bottom and top of the vertical section of the channel and one output section for the horizontal and zigzag sections of the channel.
The meshing of the present model has been done using ANSYS Meshing software. The mesh type is structured, and the element number is equal to 416,000.
Three-Phase Flow Methodology
The VOF multiphase model has been used to simulate multiphase flow in the present model. Also, inside the canal, a porous environment with a porosity coefficient of 0.1 is located.
Two inlet sections have a boundary condition of the pressure inlet with a relative pressure of 1000 pascals, and a single output section has a boundary condition of the type of pressure outlet with a relative pressure of 0 pascals.
The solver is Transient; each phase’s volume fraction change is examined in terms of time.
Three-Phase Flow Conclusion
The present model investigates the fractional volume changes of each water, air, and kerosene phase over time. This simulation was performed in 5 seconds with a time step of 0.1 seconds.
At the end of the solution process, two-dimensional and three-dimensional contours related to the pressure, velocity, and volume fraction of each of the water, air, and kerosene phases are obtained. All contours are obtained at the last second of the simulation process.
