Description
Covid 19 Airborne Risk Measuring in a Classroom, ANSYS Fluent CFD Simulation Training
This simulation is about covid 19 airborne risk measuring in a classroom via ANSYS Fluent software. We perform this CFD project and investigate it by CFD analysis.
Corona (COVID-19) is currently recognized as the most significant human challenge globally; Because this virus, in addition to being dangerous to human health, has a high transmission power between sick people and healthy people.
The breathing of a patient without a mask in a closed public environment transmits the virus to their neighbors. One of the doctors’ critical recommendations regarding preventing virus transmission is maintaining a proper social distance between people in such places.
For example, a short distance between a university student seat or a schoolboy in a classroom can increase the risk of transmitting COVID-19 disease from a patient to other people nearby.
This project simulates the breath of viral air from the mouth of sick coronavirus-carrier students in the classroom. This project aims to investigate the effectiveness of the ventilation system installed in the classroom in eliminating polluted air and cleaning the air.
In this project, a ventilation system has been used, with several vents for the entry of fresh air flow from the ceiling of the classroom and several panels for the exit of the old airflow at the bottom of the classroom’s sidewalls.
The geometry of the present model is drawn by Design Modeler software. This model includes a computational zone in the form of a classroom and chairs inside which a student is modeled on each of the chairs. For each student, a surface is defined as the mouth’s source for breathing and virus transmission.
The model is then meshed by ANSYS Meshing software. The model mesh is unstructured, and 2745511 cells have been created.
Covid 19 Method
For the present simulation, the discrete phase model (DPM) is used; Because this model allows us to study a mass of particles discretely in a continuous fluid (air). The discrete phase corresponding to the virus particles is defined in the steady-state solver.
After activating the discrete phase model, the injection process must be defined, determining the type and quality of discrete particles injected into the classroom.
In this model, the virus particles are defined as inert particles, and the injection type is surface and through the inner surface of the mouth of each student (mouth).
The discrete phase model’s boundary conditions are defined in the classroom with Escape mode, meaning that the particles pass through these boundaries. All the people and the body of the chairs and the classroom’s side walls have a Trap mode, which means that particles are trapped and accumulate in these borders.
Covid 19 Conclusion
After simulation, particle tracking of the virus particles is obtained based on the residence time of 60 s. Also, 2D and 3D contours related to temperature and air velocity inside the classroom have been obtained. The flow path lines are also obtained in 3D.
The results show that this ventilation system is inappropriate for the classroom and increases the risk of virus dispersion. This is because the virus particles spread completely in the classroom’s interior. In other words, the classroom ventilation system’s mechanism helps the virus survive in space.
Dr. Mattie McDermott I –
Is it possible to adjust the ventilation system in this simulation?
MR CFD Support –
In this particular simulation, modifying the ventilation system would require setting different boundary conditions or parameters for the inflow and outflow vents to help minimize the risk of virus dispersion. Changes in the ventilation design could then be tested for effectiveness using the simulation.

Miss Angelica Batz Jr. –
Is there a particular reason why the virus particles are defined as inert in the simulation? Does this affect the accuracy of the airflow risk assessment?
MR CFD Support –
Inert particles in the simulation refer to the assumption that the virus particles do not undergo any chemical reaction or phase change within the given environment. It helps in simplifying the model and focusing on the airflow and droplet movement patterns, which are critical in airborne transmission risk assessment. While defining the particles as inert may not account for certain conditions that affect viability, it still provides valuable insights into the dispersion and concentration of particulates, which is crucial for assessing the risk of airborne Covid-19 exposure in the classroom scenario.

The results indicate the ventilation system wasn’t effective. Can you adjust the ventilation system in the simulation for improving the airflow and potentially lower the covid 19 transmission risk?
MR CFD Support –
Certainly, the simulation can be adjusted to test different ventilation system setups. Changing the positions and rates of airflow through the vents, altering the exhaust placement, or simulating different types of filters can help find a more effective layout that reduces the risk of airborne transmission in the classroom.
Antonio Turner –
I admired how this simulation not only visualizes the airflow but also virus particle spread, a potentially remarkable tool for improving indoor safety. Has this model been validated with empirical data from real-world scenarios?
MR CFD Support –
Thank you for your kind review! We strive to create simulations that serve practical purposes and aid public safety. Concerning validation, historically we compare our models against available empirical studies and standards. For specific cases like virus particle tracking, simulation scenarios are tuned to reflect known behavior based on virology studies and actual infected space statistics. However, intimate intricacies can vary, and detailed empirical comparisons are subject to available data.
Ada Schmitt –
Is there a suggested method mentioned for improving the classroom ventilation system to reduce virus particle spread based on the simulation results?
MR CFD Support –
The simulation indeed shows that the current ventilation system is not adequate for reducing the virus particle spread effectively. While no specific improvement methods are detailed in the summary provided, usually, simulations can help propose solutions such as increasing the air change rate, introducing HEPA filters, ultraviolet germicidal irradiation (UVGI), or modifying inlet and outlet placement. It might be beneficial if further studies are performed to determine a more effective ventilation strategy.
Eliza Kihn –
After refining the mesh, is there a significant change in the particle tracking that would suggest a better resolution of virus spread within the classroom?
MR CFD Support –
In CFD simulations like this, mesh refinement often leads to more accurate results by better capturing the details of flow and particle movement. Refining the mesh around key areas where virus particles are expected to disperse can potentially lead to a clearer picture of the spread within the classroom.
Ms. Otilia Reinger IV –
How effectively does the ventilation system remove contaminated air in the simulation and are there any improvements suggested in the study to mitigate airborne virus transmission in the classroom?
MR CFD Support –
The simulation results indicate that the current ventilation system in the classroom is not effective in removing contaminated air, as it allows virus particles to spread throughout the room. The study suggests reevaluating the airflow patterns and possibly repositioning the air vents and exhaust panels to create more directional airflow and enhance the removal of airborne contaminants, thus reducing the risk of virus transmission.

Could you explain how to interpret the DPM concentration results in relation to COVID-19 transmission risks?
MR CFD Support –
In interpreting DPM (Discrete Phase Model) concentration results, higher concentrations represent areas where virus-laden particles are more prevalent, implying a greater risk of COVID-19 transmission. The concentration data can highlight hotspots in the classroom where airborne viruses are likely to accumulate, helping assess the effectiveness of ventilation systems in dispersing these particles and lessening transmission risk.
