Description
Description
The present problem simulates two-phase mixing by mixing tank by ANSYS Fluent Solver. A mixing tank typically consists of a cylindrical vessel and one or more impellers. The impellers are driven by an external motor that rotates them. When the impellers rotate, they create a flow of fluid in the tank. This flow can be axial (up and down) or radial (outwards towards the wall of the tank), depending on the type of impeller used. The fluid flow causes the substances in the tank to move and collide with each other, leading to their mixing.
The closed mixing tank contains water liquid while the impeller starts rotating with 240 rev/min angular velocity, creating a massive vortex in the middle of the tank.
The geometry of the present model is three-dimensional and has been designed using Design Modeler software. We do the meshing of the present model with ANSYS Meshing software. The mesh type is unstructured, and the element number is 2,519,007.
Methodology
The Eulerian multiphase model has been used to simulate the present model. In this simulation, the base fluid is defined as a liquid with a density of 998.2 kg/m3 and a viscosity of 0.001003 kg/m.s, and the secondary fluid in the form of particles with a density of 7800 kg/m3 and a viscosity of 0.01 kg/m.s is defined. The type of particle dispersion in the base liquid is defined in iron-powder form, and the particle diameter is defined as 1e-05m.The closed mixing tank contains water liquid while the impeller starts rotating with 240 rev/min angular velocity, creating a massive vortex in the middle of the tank.
The Mesh Motion method is enabled to model the rotational movement of the impeller. In this method, two different zones with interfaces between them should be created, and the rotating zone, which contains the impeller, would rotate independently of other stationary zones.
The solution is Unsteady, and the k- Ꜫ model is chosen to simulate the turbulence of the flow.
Conclusion
Since the main purpose of the issue is to investigate water movement inside a mixing tank, its related contours can be shown in the figures. Two-dimensional contours related to pressure, velocity, as well as turbulent intensity were obtained.
In the case of pressure, it is visible that the amount of water pressure in front of the impeller is much more than the amount behind it.
As was expected, the speed of the flow behind the impeller is more than in other areas in the domain. Also, the turbulent intensity parameter shows us the turbulence all over the tank.
This project investigates the rotating wall’s effect on Eulerian multiphase turbulent flow.
After the solution process, the two-dimensional and three-dimensional contours related to pressure (for mixing), velocity (for water phase and secondary fluid phase), the volume fraction of water and secondary fluid, as well as path lines (water and secondary fluid), have been obtained.
Two-dimensional contours are presented in two sections, YZ and XY.

Could you expand on how the Eulerian multiphase model is configured and what are the key setup parameters in the simulation of the mixing tank with iron powders?
MR CFD Support –
In the Eulerian multiphase model for the mixing tank simulation, the key setup parameters include defining two separate phases with distinct material properties. The base fluid (water) has a density of 998.2 kg/m3 and a viscosity of 0.001003 kg/m.s. The secondary phase is comprised of iron powder particles with a density of 7800 kg/m3, a viscosity of 0.01 kg/m.s, and particle diameter set to 1e-05 meters. Additionally, the simulation is unsteady and utilizes the k-omega SST model for capturing turbulence effects. The mesh motion method allows the impeller to rotate at 240 revolutions per minute, creating flow dynamics that result in mixing within the tank.

Mr. Clifford Pouros –
The description mentions utilizing the k-epsilon turbulence model, can you explain why this is the case instead of using a different turbulence model for the simulation?
MR CFD Support –
The k-epsilon turbulence model is chosen for this simulation because it provides a good balance of accuracy and computational efficiency. This model is known for being robust and reliable for a wide range of turbulent flow problems and is a common choice for mixing applications. Moreover, it effectively addresses the turbulent kinetic energy (k) and its rate of dissipation (epsilon), which are significant in predicting the mixing dynamics and turbulent energy distribution within the mixing tank.

Harvey McLaughlin II –
The multiphase model was really insightful, but could you please clarify how the particles’ velocity distribution is affected by the impeller’s motion and the initial suspension condition?
MR CFD Support –
The impeller’s rotation generates a complex flow pattern inside the tank. The particles’ velocity distribution will be primarily influenced by the turbulent flow currents created by the impeller blades. Furthermore, the initial condition of particle suspension, such as uniform or concentrated at specific points, will also play a role in how quickly the particles are dispersed throughout the liquid phase.
Miss Angela Bauch –

Kris Heidenreich –
The project’s results seem highly detailed. Has there been an evaluation of the mixing efficiency, such as homogeneity over time?
MR CFD Support –
Thanks for your positive feedback! The analysis focuses on the flow characteristics within the tank such as pressure and velocity, and provides insights into the turbulent intensity. However, the simulation specifically captures the rotational effects of the impeller on the flow and dispersion of particles. Determining mixing efficiency is a more advanced application that relies on additional diagnostic measures such as the concentration distribution over time. If these results were critical, there might be an extended study or post-processing conducted to evaluate homogeneity and overall mixing efficiency.
Ms. Elenora Berge –
In the mixing tank simulation, how is the particle diameter chosen and does it affect the simulation results significantly?
MR CFD Support –
The particle diameter in the mixing tank simulation is selected based on the size of the solid particles (iron powder) you aim to simulate. It affects the simulation results significantly as it determines how the particles will behave in the fluid and interact with it, influencing parameters such as settling velocity, collision rates, and mixing efficiency.
Moshe Douglas –
I found the simulation on the mixing tank with iron powder fascinating! I appreciate the detailed breakdown of both the methodology and conclusions. Could you share some insights on how changing the impeller speed might affect the mixing efficiency and distribution of iron powder within the tank?
MR CFD Support –
In this simulation, impeller speed directly influences the flow pattern, mixing rate, and overall homogeneity of particle distribution. Increasing the impeller speed would enhance the turbulence and kinetic energy, leading to a more fine and thorough mix where the iron powder distribution is more uniform. However, overall mixing efficiency can be complex as excessively high speeds can create undesirable flow patterns like vortex formation, or even damage particles. It’s about finding an optimal balance for the specific application requirements.
