In this project, based on the CFD method and using ANSYS Fluent software, an attempt has been made to simulate virus particles’ release from a patient’s mouth inside a bank. We perform this CFD project and investigate it by CFD analysis.

The present model is designed in three dimensions using Design Modeler software.

The model’s geometry includes a computational domain of the interior of a bank that includes a table, two chairs, and two people. In this modeling, one of the two humans is a sick person. We defined him as the virus’s source via cough.

This model assumes the mouth as the reference surface of the discrete phase virus release. In this simulation, two different geometric models are designed, including a case with no plastic cover and another case considering a thin plastic cover between two people on the table.

The meshing of the model has been done using ANSYS Meshing software. The element numbers are 1570219 and 1618366 for the first case (without plastic cover) and the second case (considering plastic cover), respectively.

Also, a transient solver has been used due to the nature of the project (i.e., particle/virus dispersion).

Plastic Cover Methodology

This study investigates coronavirus particles’ ability to spread inside the bank from a bank customer to a healthy bank employee. This simulation process is performed in two different modes.

In the first modeling, no cover is located between the client and the bank employee to show the virus’s transmission power. In the second model, an attempt is made to make a thin plastic cover between them.

The cover should be defined to demonstrate the process of preventing the transmission of virus particles as a barrier. For the present simulation, the discrete phase model (DPM) is used; Because this model allows us to study a mass of particles discretely or bit by bit in a continuously fluid space.

The physical models of discrete particles defined in this simulation include two-way turbulence coupling, meaning two-way interaction between continuous and discrete phases activating the interaction with continuous phase mode.

Stochastic collision means irregular droplets colliding with each other, coalescence means droplets merging, and breakup implies the droplets’ collapse. The type of discrete phase behavior will also be time-dependent and with a time step of 0.001 s (activating the unsteady particle tracking mode).

After activating the discrete phase model, the injection process must be defined, determining the type and quality of discrete particles injected into the model. In this model, injection particles are defined as Droplets; Thus, water is defined as droplets, and water vapor is defined as an evaporating gas species.

The injection is performed superficially and through the Surface of the patient’s mouth. According to this definition of injection, virus particles from a sick human cough are physically expelled from the patient’s mouth by water droplets evaporating in space.

These virus droplets have a temperature of 310 K, a velocity of 32 m/s, and a flow rate of 0.018 kg/s, emitted at intervals of 0 s to 0.1 s.

The virus particle size during propagation is not constant, and the rosin-rammler-logarithmic distribution method is considered for the diameter’s size.

Following this method and the suitable formulation, the values ​​related to the minimum, maximum and average diameter size determine the exponential parameter of the spread and the number of diameters per injection.

It should be noted that the Droplet mode is applied when the species transport model is also activated. In this model, three different gases, including oxygen (O2), nitrogen (N2), and water vapor (H2O), are considered, and thus the computational area of ​​our model will have airflow.

Also, the RNG k-epsilon model and energy equation are enabled to solve the turbulent fluid equations and calculate the temperature distribution inside the domain.

Plastic Cover Conclusion

At the end of the solution process, we obtain particle tracking of the virus particles at different time intervals of the simulation process. This particle sequence is based on the residence time of the particles and the particle diameter size.

We perform this simulation process in two modes, with and without the plastic cover. The effect of plastic cover in preventing coronavirus dispersion is evident from the results, demonstrating how the modeled cover can prevent the spread of the virus.

    What were the specific benefits observed with the plastic cover in the simulation?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      The simulation showed that the plastic cover effectively prevents the spread of virus particles by acting as a barrier. It significantly reduced the number of virus particles transmitted between the client and the bank employee, indicating its potential to curb the transmission of infections like COVID-19 in indoor public spaces such as banks.

    The study is truly intriguing! Could you clarify how the plastic cover’s effectiveness was assessed in the simulation, particularly regarding the virus particles’ dispersion?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      In the simulation, two scenarios were compared: without a plastic cover and with a plastic cover. The effectiveness of the plastic cover was assessed by tracking virus particle dispersion in both scenarios. In the case with the plastic cover, the model evaluated how the cover acted as a barrier restricting the transmission of virus particles from the infected person to the healthy bank employee. The discrete phase model (DPM) allowed for observing the behavior and interaction of the particles with the plastic cover, providing a visual representation and quantitative data on the particles’ spread and the cover’s effectiveness.

    I was fascinated by the study on the effectiveness of plastic covers in banks. Can you explain further how the cover impacts virus particle behavior compared to when there is no cover present? Does it show any disturbance in airflow that could affect virus transmission?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      The plastic cover acts as a physical barrier that prevents the droplets containing the virus particles from directly reaching the bank employee. When no cover is present, the virus particles can travel freely by following the airflow, potentially reaching the healthy individual. The presence of the cover changes the airflow pattern, causing a disturbance that redirects the airflow. This disruption helps to reduce the number of particles that can reach the other side of the cover. The simulation compares two scenarios—one with and one without the plastic cover—showing how the tailored use of the cover diminishes the likelihood of virus transmission due to altered airflow and particle trajectories.

    I found the details of the methods on virus particle distribution very comprehensive. How effective was the plastic cover in preventing the spread compared to having no cover at all based on your results?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      Our CFD simulation results clearly demonstrated the efficacy of the plastic cover. When the plastic cover is present, it acts as a barrier and significantly restricts the spread of virus particles from the infected individual to the bank employee, in comparison to the scenario where no cover is used. Therefore, the plastic cover is highly effective in preventing virus dispersion between the two individuals in the bank setting.

    Did the simulation show any specific situations in which the plastic cover was less effective, or did it consistently prevent the spread of virus particles regardless of particle size or other variables?

    • Avatar Of Mr Cfd Support

      In the simulation, the plastic cover effectively prevents the spread of virus particles in both scenarios, regardless of the size of the particles or other variables. The results demonstrate consistent prevention of virus transmission with the inclusion of the plastic cover barrier.

    This CFD simulation is fascinating. Does the simulation take into account changes in cough dynamics, such as varying droplet sizes or cough strength?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      Yes, the simulation does consider such variations. Droplet size is distributed using the rosin-rammler-logarithmic distribution to account for a range of droplet sizes emerging from a cough. The simulation also defines a specific initial velocity and temperature for the expelled droplets to mimic the dynamics of a cough.

      Thank you for your kind words and interesting question. However, the information provided does not detail varying cough intensities or plastic cover sizes. It solely focuses on the predefined setup mentioned in the description with specific input parameters. For broader analysis, additional simulations with varied conditions would indeed be required.
