Air Freshener Spray Device CFD Simulation, ANSYS Fluent 

This project is related to the numerical simulation of the Air Freshener Device using Ansys Fluent software.

The air freshener is used to spray aromatic substances. This device is used in homerooms and public places. The mechanism of these devices is based on the spray. The aromatic liquid is filled in the chamber of these air fresheners. Then by spraying, they spread in the surrounding space.

We modeled the geometry of the project using Design Modeler software.

The geometry is related to an air freshener. The computational zone includes a sample box around this device to study the spraying process in this space.

Then we meshed the model with Ansys Meshing software. The model mesh is unstructured, and the number of cells is equal to 357758.

Air Freshener Methodology

In this project, we have simulated the process of spraying fragrant particles. So we have to use the Lagrangian approach. According to this approach, we should investigate particle by particle in a discrete space.

Then we used the Discrete Phase Model (DPM). Then we have defined an Injection for dispersing discrete particles.

The injection type is Conical, and the particle type is the Droplet. The injection of particles is unsteady and happens within 0.4 seconds.

To use droplet injection, we have also defined the Species Transport Model. We defined three volumetric species, including oxygen, nitrogen and water vapor.

Air Freshener Conclusion

After the solution, we studied particle tracking. At different times, we have investigated particle tracking. We also obtained an animation of particle injection.

By checking the particle over time, the spraying process of this device can be studied. The results show that the simulation is done correctly. This device sprays fragrant particles well.

    The simulation details provided really put into perspective the intricate process of modeling spray devices! I’m really impressed by how you’ve implemented the Lagrangian approach for particle distribution through the Discrete Phase Model. I’m especially curious about how you set up the species transport model, particularly for the reaction mechanism, if at all, that considers interaction between the fragrance substances and ambient air.

      In this simulation, the species transport model is used to track the concentration of different gaseous components. While the primary focus is on the distribution of fragrance particles as a discrete phase, the species transport model helps provide a detailed representation of gaseous species, like oxygen and nitrogen. In the case of this air freshener device, we do not specifically model chemical reactions between the fragrance substances and the ambient air. Instead, we monitor the dispersion of water vapor (representing the fragrance particles) within the airspace, considering the primary physical dispersal without detailed chemistry.
