Ansys Discovery Room Ventilation Simulation
Hello, this is Ertan Taskin from Ozen Engineering. In this video, I will be demonstrating an ANSYS Discovery application on air distribution in a classroom, starting from geometry generation to the simulation.
Loading Geometry
I have already opened the Discovery app and I'm going to load the geometry. As you can see, I have a classroom environment with tables, desks, walls, doors, windows, shelves, and a teacher's desk. The geometry is already available, but there is no ceiling. We need to create a fluid domain to work on.
Creating an Enclosure
To create the fluid domain, we will:
- Go to the repair section and create an enclosure.
- Decide how far from the main domain to create the enclosure. I want to align the top of the enclosure with the top of the room to create the ceiling.
- Set the default cushion to zero to fully encapsulate the body.
Once confirmed, we can exclude everything else to clearly see the created volume. Suppress the unnecessary components for the physics.
Defining Ventilation Locations
There are no predefined ventilation locations, so we will:
- Create a sketch on the surface to define ventilation inlets and outlets.
- Assume a 24-inch rectangle for the inlet and a 12-inch rectangle for the outlet.
- Use the imprint function to define these as boundary locations.
Setting Boundary Conditions
With the fluid domain generated and name selections set, we move on to the simulation phase:
- Define the fluid flow features such as inlets and outlets.
- Set the mass flow rate for the inlets to 8.3 kilograms per second, which corresponds to 500 kilograms per minute airflow per vent.
- Define zero pressure conditions for the outlets.
Simulation Setup
Additional settings include:
- Setting gravity in the negative Z direction.
- Selecting air as the material for the simulation.
Running the Simulation
Once the setup is complete, we run the simulation. During the simulation, we can:
- View vectors and particles to see how air is distributed.
- Rotate, zoom in, and zoom out to observe the airflow.
Post-Processing
Post-processing options include:
- Creating velocity contours to visualize airflow.
- Using isosurfaces to analyze velocity distribution.
- Creating cut planes to examine air distribution on different planes.
Conclusion
In this video, we covered the basic steps of air distribution calculations in a classroom using the Discovery application, from geometry generation to simulation and post-processing. Thank you for watching.
Hello, this is Ertan Taskin from Ozen Engineering. In this video, I will demonstrate an ANSYS Discovery application for air distribution in a classroom, from geometry generation to simulation.
I have opened the Discovery app and loaded the geometry, which includes a classroom environment with tables, desks, walls, doors, windows, shelves, and a teacher's desk. There is no ceiling, so I will create a fluid domain to work on.
To do this, I will go to Repair, create an enclosure, and flash the top of the room to create the ceiling. I will then exclude everything else to clearly see the created volume. I will name the selection as "ceiling" and define the boundary conditions for the fluid flow.
Next, I will set the inlets and outlet conditions. I will create two inlets with a mass flow rate of 8.3 kilograms per second, which corresponds to 500 kilograms per minute airflow per vent. I will define the outlets with a zero pressure condition.
I will set the gravity in the negative Z direction and define the material as air. Once the simulation is complete, I will post-process the results by creating velocity contours, isosurfaces, and a cut plane to see the distribution of air in different parts of the classroom. Thank you for watching.
