Transfer Chute Analysis
Hi everyone, today we are going to set up and assess a basic model in Ansys Rocky using the supplied geometry files. Let's begin.
Model Description and Setup
We begin with a description of our model to better understand what the simulation includes. Next, we define the physics involved, keeping some options as default. Import the geometry files according to the instructions. Notice that the geometry is made of several components. You can use the pan, rotation, and zoom controls with your mouse.
Steps to Set Up the Model
- Generate the surface for particle release, which will be defined as the inlet boundary condition later.
- Adjust the transparency of all components in the geometry to improve visualization.
- Create the motion frames. Two translations will be applied: one for the feed conveyor and another for the receiving conveyor.
Material and Interaction Properties
Here, you see the material properties. We will work with the default values. Once we define the material properties, we need to assign them to each geometry.
Defining Particle Interactions
- Particles with particles
- Particles with the conveyors
- Particles with the walls
Create the particle shape and size. Finally, visualize the particles based on the setup.
Boundary Conditions and Solver Setup
Define the inlet boundary condition by selecting the rectangle created previously and typing the inlet mass flow rate. Specify the range of time to apply this boundary condition during the simulation.
Solver Setup
- Specify the total simulation time
- Set the time step
- Choose the number of cores or the GPU to process the solution
Results and Visualization
It's time to get some results. Let's begin with the particle flow colored by velocity or residence time. Use the play button to run the animation, or select a specific instant of time from the list.
Quantitative Information
- Plot the number of particles released from the inlet and those exiting the domain.
- Create a plot of the particle distribution on the lower conveyor. Are the particles distributed evenly across the entire surface?
To shift this plot, create a region of study. Then, create two planes with different normal vectors to split this region into equal parts. Follow the procedure to accomplish this. A group of particles will have different colors, but the graph will show the imbalance.
Multi-time Plot
Go to the Window menu and select Multi-time plot. Drag and drop particle mass onto the plot for both planes.
Creating a Video
The final step is to create a video. Organize the visualization of the results you want to show and adjust the position of the geometry in the window. Select the frames from the set of transient results. Click on the icon to save the file. You will be able to play the video at the end.
And that's all for today. Thanks for watching.
