I would like to ask a question about a system developed in Ansys Fluent. In the imaging system, nitrogen air enters through the upper region of the tube and exits through the lower region, colliding with the base and spreading throughout the environment. How do I spread the air around the room in Fluent? Because when I put an inlet and an outlet in the tube, the air just makes its way through the tube and stops. How to make it continue its course until it crashes into the base? Thank you in advance.

Here are a few steps to guide you:
Domain Extension: Extend the domain beyond the tube so Fluent can model airflow as it exits the tube and spreads across the room.
Boundary Conditions: Set an appropriate outflow or pressure-outlet boundary condition at the far sides of the room (or environment). This will simulate the air dispersing after colliding with the base and spreading through the environment.
Turbulence Model: Use a turbulence model, such as k-epsilon or k-omega, to properly simulate the mixing of nitrogen air with the surrounding air. This is crucial for simulating how the gas behaves as it exits and spreads.
Source Term or Fan Model: If your system needs to simulate enhanced air dispersion or interaction with surrounding air, you may need to define a source term or use a fan model to represent forced dispersion, depending on the specifics of your design.
Velocity and Mesh: Ensure the mesh is fine enough, especially near the outlet and the region where air collides with the base. Adjusting the inlet velocity and checking the mesh can improve simulation accuracy. itemd2r
These adjustments should help you simulate the air's movement through the tube and the resulting dispersion into the surrounding environment.
Let me know if you need further details or if there's more information on your setup!
