Powder distribution in Mixer CFD Simulation
Project Description
In this project, we are simulating the Powder distribution inside the stationary fluid in a mixer tank. First, the powder is settled at the bottom of the mixer tank. Then, the mixer propeller starts rotating to disperse the powder. This simulation is costly, so it is only performed for a limited time.
The geometry of the mixing tank is designed using SpaceClaim software. Then, it is meshed in ANSYS Meshing. In total, about 3,000,000 cells are generated.
Methodology
The working fluids are a mixture of powders and water liquid. These phases are modeled using the Eulerian multiphase model.
The powder as the secondary phase has a granular nature, so a granular option is used.
Mesh motion is also used to model the rotation of the mixer propeller. The propeller is rotating at 30 rpm.
Results
After the solution, contours are given. The simulation results show a clear pattern of powder distribution in the fluid after a certain amount of time of mixing. The contour clearly shows that the powder is layered, with the largest concentration at the bottom of the container. You can see a thin layer of transition just above this area with a lot of powder.
This suggests that the powder is spread out in a gradient. The pattern of the powder's distribution shows that the mixing process has not yet evenly spread the powder throughout the fluid. This is expected since the mixer has only a short turning time. It is clear that there is a center shaft or impeller, which could change the flow patterns and powder distribution close to it.
